1 GENERAL
1.1 Field of Application
The GOLD units are designed for use in comfort ventilation applications. Depending on the variant selected, GOLD units can be
utilised in buildings such as office buildings, schools, day nurseries, public buildings, shops, residential buildings, etc.
GOLD units equipped with plate/coil heat exchanger (PX/CX) and
separate GOLD supply air and extract air handling units (SD) can
also be used for the ventilation of moderately humid buildings;
however not where the humidity is continuously high, such as in
indoor swimming baths.
The separate GOLD supply air and extract air handling units (SD)
are designed for applications in which the supply air and extract
air flows need to be completely separated from one another or
where, due to limited available space, separate units for supply
air and extract air are needed. They can also be used individually
if only one of the variants is needed.
In order to fully obtain all the benefits the GOLD system has to
offer, it is important to take the special characteristics of the
air handling units into account when planning them into the
project, installing, adjusting and operating them.
The air handling unit in its basic version should be installed
indoors. The TBTA/TBTB accessory should be used if the air
handling units are installed outdoors. If the duct accessories are
installed outdoors, they must be housed in an insulated casing
(type TCxx).
Important!
Always read the safety precautions in Section 2
about what generally applies concerning risks
involved and who is qualified to carry out the work,
and carefully follow the installation instructions that
are given in each section.
The product identification plates are located on the inspection
side of the air handling unit and on a wall inside the fan section.
Refer to the particulars on the product identification plate when
you contact Swegon.
1.2 Mechanical Design
The GOLD is available in 8 physical sizes and for 14 airflow
ranges.
Its sheet steel exterior is painted in a beige colour. NCS2005Y30R. Its door handles and the upper part of the junction
hood are painted light grey. NCS 53502-B. Its interior material
is mainly galvanized sheet steel with 50 mm thick intervening
insulation.
The size 12-30 GOLD units with plate heat exchanger (PX) or
rotary heat exchanger (RX) with air intake from above and the
separate size 04-08 supply air and extract air units (SD) as well as
the GOLD RX Top are equipped with pleated, class F7 filters. The
units in other variants/sizes have class F7 supply air and extract
air filters made of glass fibre.
The type RECOnomic rotary heat exchanger is variable speed
controlled and has a temperature efficiency of up to 85%.
The plate heat exchangers are as standard equipped with by-pass
and shut-off damper for variable and automatic control of the
heat exchanger’s efficiency on heat recovery.
The coil heat exchangers in the one-piece units (CX) are supplied
complete from the factory; including mounted the pipework
package with all the necessary components. The system is normally filled with liquid, vented, adjusted and performance-tested
prior to delivery, but can be ordered in unfilled condition e.g. for
housing improvement projects or if a liquid mixture other than
30 % ethylene glycol is required. The pipework package is available loose as an accessory for separate, size 14-80 supply air and
extract air handling units (SD)
The supply air and extract air fans are of GOLD Wing+ type, an
axi-centrifugal fan with backward-curved blades. The fans are
direct-driven and have a motor control system for variable speed
control.
1.3 Control System
The control system is microprocessor-based and is integrated
into the unit. It controls and regulates the fans, heat exchanger,
temperatures, airflows, operating times and a large number of
internal and external functions as well as alarms.
1.4 Environmental Documentation
Environmental documentation with the Dismantling instructions
for recycling and the Environmental Declaration are included as
appendices in these instructions.
The air handling unit is designed for simple to dismantling into
its natural parts. When the unit has reached the end of its useful
product life, engage an approved recycling company for scrapping.
Approximately 94% of the total weight of the GOLD is can be
recycled.
Swegon AB is associated with the REPA Register, no.

2 SAFETY PRECAUTIONS
All staff concerned shall acquaint themselves with these
instructions before beginning any work on the unit.
Any damages to the unit or its components caused by
improper handling or misuse by the purchaser or the fitter
cannot be considered subject to guarantee if these instructions have not been followed correctly.
Warning
Only an authorised electrician or qualified service
personnel trained by Swegon shall be permitted
to modify the air handling unit in conjunction with
electrical installations or the wiring of external functions.
2.1 Safety Isolating Switch/Main Switch
Size 04/05, 08, 12, 14/20 and 25/30 one-piece GOLD
units with rotary (RX), plate (PX) or coil (CX) heat
exchanger: The safety isolating switch is located externally
on the junction hood.
Size 35/40, 50/60 and 70/80 one-piece GOLD units with
rotary heat exchanger (RX): The safety isolating switch is
externally located on the door of the centre section of the
unit.
Size 35/40 one-piece GOLD units with coil heat exchanger
(CX): The safety isolating switch is located on the left
side of the electric equipment cubicle in the centre section of the unit. Size 50/60 and 70/80 air handling units:
The safety isolating switch is located in a plastic enclosure
below the electrical equipment cubicle in the centre section of the unit.
Separate supply air and extract air handling units (SD): The
safety isolating switch is located on the inspection side by
the inspection door of the fan section.
The air handling unit shall normally be started and
stopped via the hand-held micro terminal, not via the
safety isolating switch.
Always switch off the safety isolating switch before servicing the unit if not otherwise specified in the pertinent
instructions.
2.2 Risks
Warning
Before carrying out any work, make sure that the
power supply to the unit has been isolated.
Risk areas with rotating parts
Moving parts are the fan impeller, drive pulleys of the
rotary heat exchanger, if fitted, and by-pass/shut-off
damper of the plate heat exchanger, if fitted.
The lockable inspection doors serve as protection from
contact with the fans and the heat exchanger. If the fan
outlets aren’t connected to any duct, they must be fitted
with a protective screen (wire mesh).
Warning
The inspection doors on the filter/fan sections must
not be opened while the unit is in operation.
Under normal operating conditions, use the stop
button on the hand-held terminal to stop the air
handling unit.
Wait until the fans have stopped rotating before
opening the inspection door.
The air pressure inside the filter/fan section is positive, which means that the door can fly open.
2.3 Safety Guards
The cover of the electric equipment cubicle serves as a
safety guard in the size 04/05 and 08 one-piece air handling units with rotary heat exchanger (RX), as well as
on all the other variants (PX/CX/SD). On size 12, 14/20,
25/30, 35/40, 50/60 and 70/80 one-piece air handling
units with rotary heat exchanger (RX), the lockable door
over the electrical equipment cubicle serves as a safety
guard.
Only a qualified electrician or trained service technicians
shall be allowed to remove the safety guards.
Warning
The power supply to the unit shall be isolated by
switching off the safety isolating switch before
removing the safety guard.
As long as the air handling unit is operating, the
safety guards must always be mounted, all inspection doors must be closed, and the junction hood
on the top of the unit must be mounted.
We reserve the right to alter specifications without notice.
2.4 Glycol
Glycol is used in the GOLD air handling units with
coil heat exchanger. Never pour glycol down a
drain; collect it in a receptacle and leave it at a
recycling centre, petrol station, or the like. Glycol
is highly dangerous to consume and can cause
fatal poisoning or damage the kidneys. Contact a
doctor! Avoid breathing glycol vapour in confined
spaces. If you get glycol in your eyes, flush them
thoroughly with water (for about 5 minutes). If
glycol splashes on your skin, wash with soap and
water.

3 COMMISSIONING
L
L
≈ 0,5xL
≈ 0,5xL
3.1 General
Sequence for commissioning:
1. Check that there are no foreign objects in unit, ducting system
or functional sections.
2. Check that rotating heat exchangers (only GOLD RX) rotate
easily. On sizes 50-80, the rotating heat exchanger must be
angled slightly towards the filter, see diagram below.
If the angle needs adjusting, see special instructions for angle
adjustment, rotating heat exchangers.
GB.GOLDSK509.091101
GOLD RX,, sizes 50-80: The illustration shows the factorypreset rotor inclination in a unit with Fan Arrangement 1.
The inclination must always be towards the filter, which
means that the inclination for Fan Arrangement 2 is in the
other direction.
3. Turn the safety isolating switch to the ON position (I).
4. Select the language desired, if you have not already done so.
See Section 5.2 or 13.1.
5. The unit has factory settings which make it ready to use. See
Section 19.2 Commissioning record.
However, in many cases, these settings need to be adjusted to
suit the current installation.
Program the switch clock, operating conditions, temperatures,
airflows and functions according to the procedures in Sections
4-15.
Select whether l/s, m3/s or m3/h shall be used as the flow unit.
(INSTALLATION LEVEL in the HAND-HELD MICRO TERMINAL
menu).
Fill out the Commissioning Record and save it in the document
pocket of the unit.
6. Activate, if needed, manual or auto operation (MAIN MENU)
or lock the speed of the fans (AIR ADJUSTMENT menu).
Adjust the ducting system and air devices as described in Section
3.2.
7. Check and adjust, if required, the pressure balance in the unit
as described in Section 3.3.
8. Finish off with a filter calibration as described in Section 6.4.2.

GB.GOLDSK509.091101
3.2 Adjusting the Duct System
and Air Devices
In order to prevent the fans from consuming more power
than necessary, it is important to keep the pressure drop in
the system as low as possible.
It is also important that ducting systems and air devices are
correctly adjusted to provide the comfort expected.
When adjusting air devices and the duct system installed
in combination with the GOLD, it is appropriate to follow
the proportionality method.
This means that the proportion between the airflows in
branch ducts stays constant even if the airflow in the main
ducts is changed. The same proportion applies to the air
devices in the installation.
When adjusting the ducting system there is provision
for locking the speed of the fans in the unit to a specific
preset flow rate, see Section 6.5.
3.2.1 Adjustment Sequence
The system should be adjusted in the following order:
1. Adjust of the air devices in each branch duct.
2. Adjust the branch ducts.
3. Adjust the main ducts.
3.2.2 Adjustment Procedure
1. Set all the air devices and dampers to the fully open
position.
2. Calculate the ratio of the airflow reading to the design
airflow of all the air devices, branch ducts and main ducts.
The air device in every branch that has the lowest ratio
should be fully open. Use this air device as an INDEX AIR
DEVICE. The same applies to branch dampers and main
dampers.
When you’ve completed the adjustments, one air device in
every branch, one branch damper and one main damper
should consequently be fully open.
3. Start adjusting the main duct that has the highest ratio
and the branch duct in the main duct that has the highest
ratio. Starting from this point enables you to “press” the
air in front of you toward the sections of the system that
have the least air.
4. Adjust the last air device on the duct branch so that
it will have the same ratio as the index device. This air
device will serve as the REFERENCE AIR DEVICE. Often
it is the last air device on the branch that has the lowest
ratio and should be open. In this case, the same air device
serves as the index device and reference device.
5. Throttle the other air devices in the branch to the same
ratio as the reference device.
Note! The ratio in the reference device will change every
time another air device is throttled, so in practice the ratio
for the reference device can be set slightly higher. The
reference device must be measured in between each air
device throttled.
6. Go to the branch that had the next highest ratio and
adjust the air devices there, etc.
Note! All branch dampers should be fully open until all air
devices have been adjusted.
7. Throttle the branch damper that had the highest ratio
to the same ratio that the branch of the lowest ratio had.
Note! Keep in mind that the index damper changes ratio;
proceed as described in item 5.
8. When all branches have been adjusted, throttle the
main dampers in the same manner.
Also see the example below on how to carry out adjust-
ments.
Example on how to carry out adjustments
– Start adjusting duct branch B, since this one has
the highest ratio.
– The last air device, B3, has the lowest ratio and
should be fully open.
Adjust the other air devices, B1 and B2, so that
these will have the same ratio as air device B3 (see
item 5 above).
– Now adjust the air devices in branch duct C. Air
device C4 should be fully open; throttle the others
to the same ratio.
– Adjust the air devices in branch duct A. The index
air device here is air device A3, which means that
you first throttle air device A4 (the reference device)
to device A3:s ratio.
Thereafter the others are adjusted to the same ratio
as air device A4.
– Throttle branch damper B to the same ratio as branch damper A,
throttle branch damper C to the same ratio as branch damper A.
Check that all dampers have the same ratio.
When the adjustment has been completed, 3 air devices and one
branch damper should stand fully open to obtain the lowest possible pressure in the system.

3.3 To Adjust the Pressure Balance
(applicable to air handling units with rotary heat
exchanger)
3.3.1 General
The pressure in the extract airflow path should be slightly
lower than that in the supply airflow path to ensure correct air leakage direction and that the purging sector in
the heat exchanger will work correctly. This ensures that
extract air will not be carried over to the supply air.
The pressure balance in the unit should be adjusted when
the ventilation system has been fully installed, all the air
devices have been adjusted and the supply air and extract
air flows are as they should be while the air handling unit
is operating normally.

Two flow adjustment plates are supplied with the GOLD RX Top.
The version of the air handling unit, i.e. right-hand or left-hand,
is the factor that determines which of the flow adjustment
plates you should install in the unit. Install the correct flow
adjustment plate at its intended location inside the air handling
unit. Scrap the other plate. See the illustration above.
Remove the fixing screws and place the flow adjustment plate in
the grooves intended for retaining it. Tighten the fixing screws.
See the illustration above.
The pressure balance can be adjusted by blanking off holes in
the flow adjustment plate with the plugs supplied with the unit.

GB.GOLDSK509.091101
3.3.2 To Ensure the Correct Leakage Direction
The adjustment plates fitted in the extract air inlet are
used for adjusting the pressure balance in the unit. The
adjustment plates are supplied separately and should be
fitted in the unit by the fitter when he connects the extract
air ducting to the air handling unit. See the illustrations on
the previous page.
Connect a pressure gauge to the pressure measurement
tappings of the unit.
The unit has four pressure measurement tappings; the two
closest to the extract air duct should be used. The blue
pressure measurement tapping measures the negative
pressure in the extract air section and the white pressure
measurement tapping measures the negative pressure in
the supply air section.
On the size 04-08 units, the pressure measurement tappings are by the junction hood and on the size 12-80 units
they are inside in the centre section of the unit.
See illustration to the right.
Note that both pressure measurement tappings measure
negative pressure.
MEASURED VALUES
The negative pressure in the extract air section should be
greater or the same as the one in the supply air section.
If the negative pressure in the extract air section is the
same or up to 20 Pa more than the negative pressure in
the supply air section, then you’ve finished this adjustment.

DEVIATIONS
If the negative pressure in the extract air section is less
than that in the supply air section, the adjustment plates
must be readjusted as follows:
1. Stop the unit, open the inspection door to the extract
air filter.
GOLD RX Top: blank off a number of holes in the flow
adjustment plate with the plastic plugs supplied with the
unit.
Other models: slightly push the flow adjustment plates
forward (close them) in the extract air intake opening.
For full face connection (duct accessory in insulated
casing): If the commissioning plate(s) is/are completely
closed and the sub-atmospheric pressure in the extract air
section is still less than in the supply air section, blank off
a number of holes in the commissioning plate with the
plastic plugs supplied.
3. Close the inspection door and restart the unit.
4. Measure the pressures.
Repeat until the negative pressure in the extract air section
is the same or up to 20 Pa higher than the negative pressure in the supply air section (0–20 Pa).
5. If the negative pressure in the extract air section is
higher than 20 Pa compared to the supply air section,
although the adjustment plates are completely open, the
leakage and purging air flow will be more than anticipated. This means that the actual extract air flow will deviate
from the preset extract airflow. The deviation increases
with increased pressure differential.

Eight different time channels can be set. If the same in-operation
times are to apply every day of the week (Mon-Sun), you need
only program one time channel. Different operation times for
each day of the week can be programmed by programming a
time channel for each day (Mon-Fri, Sat-Sun or Mon, Tues, Wed,
etc)
The time can be set as 00:00-00:00 if the deviating in-operation
period is desirable for the entire 24 hours period.
YEAR CHANNEL
The year channels make it possible to set deviating in-service
times for parts of the day during certain parts of the year. Eight
different year channels (yearly time schedules) can be set. The
year channels over-modulate the time channel during the hours
of the day and the days that the year channel is active. The year
channel dates indicate the dates between which the year channel shall apply and the year channel hours indicate the hours of
the day between which the year channel will steer the controller
to operate the rotary heat exchanger at a specified speed. Other
times within the year channel still apply to that time channel.
The time can be set as 00:00-00:00 if the deviating in-operation
period is desirable for the entire 24 hours period.
Functions for summer night cooling, prolonged operation, etc.,
operate also when the year channel is active.

8 FUNCTIONS
8.1 Temperature
Basic functions can be set at INSTALLATION LEVEL
and values are read and set at USER LEVEL.
IMPORTANT! If you intend to substantially alter the temperature settings, you should first stop the air handling
unit before doing so.
If only GOLD SD supply air handling units are installed,
they require an external room sensor for ERS and extract
air control.
8.2 Temperature Regulation
Select ERS Regulation, Supply air regulation or Extract air
regulation.
If ERS Regulation is selected, select between 1 and 2.
Control sequence for ERS regulation and Supply air regulation:
1. The temperature efficiency of the air handling unit’s
heat exchanger is modulated to provide max. heat
recovery. (Not applicable to GOLD SD without heat
exchanger).
2. After that the air heater, if installed, will begin to
generate heat.
3. If a downstream heating coil is not installed, or if the
its output is not adequate, the supply air fan will be
automatically and variably downspeed-regulated to
convey air at a lower flow rate. (If the unit is a GOLD
SD without heat exchanger, this function can be deacti
vated).
A neutral zone can be preset, which allows a lower supply
air temperature setpoint before regulation to a lower flow
rate begins. See 8.3.4
When the supply airflow is regulated to a lower rate, the
heat exchanger will have ”excess heat”, i.e. warm extract
air, giving it capacity to maintain the supply air temperature required.
As the supply airflow is regulated to a lower rate, the air
pressure in the premises will become negative and this will
instead cause outdoor air to be sucked in through leakage spots such as doors and windows. This outdoor air
will then be heated by the ordinary heating system of the
premises. (Not applicable if only a GOLD SD supply air or
extract air handling units are installed)
Downspeed regulation to lower the airflow rate occurs
from the current preset flow (high speed or low speed),
down to half of this flow rate. The degree of regulation
to a lower rate is also limited by the min flow setting of
the unit. When preset flow for low speed is near the min
flow rate, the effect of this regulation to a lower rate will
be small.

8.2.1.1 ERS Regulation
ERS regulation means Extract air temperature-Related
Supply air temperature regulation. This means that the
temperature of the supply air is regulated in relation to
the temperature of the extract air. Under normal circumstances, the supply air temperature is regulated to be a
few degrees lower than the extract air temperature. In this
way, the heat exchanger will provide optimal performance, and this means excellent operating economy. ERS
regulation is suitable for use when there is excess heat in
the premises generated, for example, by machinery, lighting or people and the supply air devices in the premises
are suitable diffusing air below room temperature.
ERS REGULATION 1
The control unit regulates the relationship between the
supply air and extract air temperatures according to a factory-preset curve.

8.2.1.2 Supply Air Regulation
Supply air regulation involves keeping a constant supply
air temperature without consideration to the load in the
premises.
This type of regulation can be used when the load and
temperatures of the premises are predictable. In most
cases a reheating coil needs to be installed; possibly a
cooling coil as well.
The following settings can be entered at USER LEVEL
under TEMPERATURE/SETTINGS:
Value Setting Factory
range setting
Supply air temperature setpoint 15-40 °C 21.5 °C
Setting range for the setpoint is limited by Min. and Max.
settings at INSTALLATION LEVEL under HAND TERMINAL.
8.2.1.3 Extract Air Regulation
Extract air regulation involves keeping a constant temperature in the extract air duct (premises), by regulating the
supply air temperature. This provides a uniform temperature in the premises regardless of the load and this type
of regulation requires the installation of a reheating coil;
possibly a cooling coil as well.
The extract air temperature is measured by the temperature sensor inside the GOLD unit. If this internal temperature sensor does not give adequate representative extract
air temperature readings, an external room temperature
sensor can be installed and wired to terminals 40-41 on
the control unit.
The following settings can be entered at USER LEVEL
under TEMPERATURE/SETTINGS:
Value Setting Factory
range setting
Extract air-/room temp. setpoint 15-40 °C 21.5 °C
Min. Supply air temperature 13-18 °C 15 °C
Max. Supply air temperature 25-45 °C 28 °C
GB.GOLDSK509.091101
Setting range for the various values is limited by Min. and
Max. settings at INSTALLATION LEVEL under HAND TERMINAL.
8.2.1.4 Temperature control, Xzone
The Xzone temperature control function is designed for
controlling one extra temperature zone via the ventilation
system.
Xzone can be used for all types of GOLD air handling
units. The function can control both reheating and cooling
in the extra zone.
The type of temperature control used for the extra zone
must be selected separately and can be different to that
used in the main zone.
For particulars of the settings, see 8. Temperature control.

8.2.2 Outdoor Temperature Compensation
Temperature
Outdoor temperature compensation can be activated if
the premises are abnormally subjected to the effects of
seasonal cold air or hot air due to leakage through large
windows, for instance.
The supply air temperature setpoint is compensated if the
air handling unit is operating in the supply air regulation
mode, and the extract air temperature setpoint is compensated if the air handling unit is operating in the extract air
regulation mode. This function will have no effect if the
unit is operating in the ERS regulation mode.
The preset temperature setpoint is influenced if the outdoor temperature drops below the preset X2 breakpoint
(winter compensation) and above the preset X3 breakpoint (summer compensation).
The settings are also applicable to one extra temperature
zone (Xzone), if required.
See the chart to the right.

8.2.3 Summer Night Cooling
The lower temperature at night is utilized to cool down
the building structure. This reduces the cooling load
during the first hours of the day. If a cooling unit is
installed, its in-operation hours will be minimized, thus
offering savings. If no cooling unit is installed, a certain
cooling effect will still be realized.
When summer night cooling function is activated, the unit
fans operate at high speed, with a supply air setpoint of
10°C, from the preset time until the conditions necessary
for stop are satisfied.
The extra temperature zone (Xzone), if any, will obtain
the same supply air set point if summer night cooling is in
operation.
Conditions to be met to start summer night cooling at the
preset time:
• The extract air temperature should be higher than the
preset value
• The extract air should be at least 2°C warmer than the
outdoor air.
• The outdoor temperature should be above the preset
value.
• Heating has not been required between 12.00–23.00
hours.
• The unit must not operate in the high speed mode or
be stopped from an external source or manually from the
hand-held micro terminal.
Conditions to be met to stop summer night cooling at the
preset time:
• The extract air temperature drops below the preset
value.
• The outdoor temperature drops below the preset value.
• Switch clock or external input calls for high speed.
• The extract air is less than 1 °C warmer than the outdoor
air.

8.2.4 Intermittent Night-time Heating
The unit is utilized to heat the premises when it is normally
stopped by the switch clock.
The function requires that an external room sensor is connected (control unit terminals 40-41) and that a reheating
coil be installed downstream of the air handling unit. The
function works best if the GOLD is equipped with an air
recirculation section and shut-off dampers for the outdoor
air and the exhaust air.
When the function is activated, the air handling unit
detects when the room temperature drops below the
preset start temperature. The unit starts with preset flows
and the supply air temperature setpoint.
If extract air fan operation is not desirable, the extract
airflow can be set to 0.
The damper output can be set to 0. This means that the
connected dampers (such as shut-off dampers for outdoor
air and extract air) will not be affected. These dampers are
normally closed when the air handling unit is stopped and
they also remain closed. The damper in the air recirculation section is opened at the same time, if one is installed.
Intermittent nighttime heating does not affect a possible
extra temperature zone (Xzone) that regulates according
to its ordinary set point, if intermittent nighttime heating
is in operation.
Conditions to be met for intermittent night-time heating
to start:
• The unit should operate in a time channel/switch clock
stop.
• The room temperature should be below set start temperature.
Conditions to be met for intermittent night-time heating
to stop:
• High speed or external/manual stop should be activated.
• Room temperature should be above the preset stop
temperature.
• Alarm with preset stop priority has tripped.
If the needed, the air handling unit fans will continue to
operate to cool the electric air heater although other conditions for stop have been met.)

8.2.5 Morning BOOST
The unit is utilised to heat the premises during a preset
period prior to the switch-in time set on the switch clock.
The function is used if the air recirculation section is
installed.
The unit starts early and uses the same operation and
temperature regulation settings as it would at the regular
start time.
If the extract air fan is not required to operate, the extract
airflow can be set to 0.
Damper output can be set to be inactive. This means that
connected dampers (e.g. outdoor air and exhaust air shutoff dampers) are not affected. Normally these dampers
are closed when the unit is stopped and thus they remain
closed. At the same time damper in the air recirculation
section opens, if one is installed.

8.2.6 Setpoint Temperature Displacement
Used for changing the supply air and extract air temperature setpoints by means of an external 0-10 VDC signal
(control unit terminals 34-35). The temperature can be
increased or decreased at certain times of the day by
means of an external switch clock or potentiometer, for
instance.
The setpoint can be influenced ±5 °C.
If the unit is operating in the supply air regulation mode,
the supply air temperature is displaced and if the unit is
operating in the extract air regulation mode, the extract
air temperature is displaced.
When the unit is operating in the ERS regulation 1 mode,
the difference between extract air and supply air is influenced. The difference cannot be less than 0 °C. The difference will decrease as the input signal increases.
If the unit is operating in the ERS regulation 2 mode, the
supply air setpoint will be offset.
When the function is activated, the setpoint is offset as
illustrated in the chart to the right.
Set point displacement does not affect a possible extra
temperature zone (Xzone) that regulates according to its
ordinary set point, if set point displacement is in operation.

8.2.7 Extra Regulation Sequence
Used for extra control functions controlled by a 0-10V
signal with ordinary temperature regulation sequence.
The function can be used for utilizing existing heating or
cooling sources, such as from a refrigerating plant. The
function can also be used for an extra cooling or heat coil.
The out signal for the extra regulation sequence is transmitted via the same terminals on the control unit as for an air
recirculation damper, if fitted (terminals 44-45).
The maximal output signal can be limited from 100 %
down to 0 %.
It is possible to combine extra control sequence with intermittent nighttime heating or Morning BOOST (requires the
IQnomic Plus accessory).
Extra regulation sequence can be selected to work in four
different positions as follows:
Cooling operation
• Comfort: 0-10 V output signal sequence after the cooling
function is controlled to 100 %.
• Economy: 0-10 V output signal sequence before the regular cooling function.
Heating operation
• Comfort: 0-10 V output signal sequence after the reheating function is controlled to 100 %.
• Economy: 0-10 V output signal sequence before the regular reheating function.

measures the extract air temperature in a larger room or in
the duct system, instead of the temperature inside the air
handling unit.

the outdoor air temperature outdoors, instead of the temperature inside the air handling unit.
As an alternative, a temperature reading can be communicated to the air handling unit from a supervisory system, for
instance.

8.3 Flow/Pressure
Basic functions are set at INSTALLATION LEVEL and
the values are read and set at USER LEVEL.
8.3.1 Fan Regulation
The type of regulation used for the supply air fan and the
extract air fan respectively can be selected individually.
8.3.1.1 Flow Regulation
Flow regulation involves operating the air handling unit
to keep the preset airflow constant. The speed of the fans
is automatically regulated to provide correct airflow even
if the filters begin to become clogged, air devices are
blocked, etc.
Constant airflow is advantageous, since the airflow always
is exactly as it was from the beginning.
It should however be noted that everything that increases
the pressure drop in the ventilation system, such as the
blocking of air devices and dust accumulating in the filters, causes the fans to run at a higher speed. This causes
higher power consumption and may also cause discomfort
in the form of noise.
8.3.1.2 Pressure Regulation
The airflow automatically varies to provide constant pressure in the ducting. This type of regulation is also called
VAV regulation (Variable Air Volume).
Pressure regulation is used when damper operations
increase the air volume in parts of the ventilation system.
The duct pressure is measured by an external in-duct pressure transducer which is wired to the BUS communication
of the control unit. The setpoint setting required (separate
for low speed and high speed) is entered in Pa.
The function can be limited so that the fan speed will not
exceed the preset max. permissible values.

8.3.1.3 Demand Control
The airflow required is regulated in response to 0-10 V
input signals from an external sensor, such as a carbon
dioxide sensor, connected to control unit terminals 30-33.
Required setpoint (separate for low speed and high speed)
is set as a percentage of the input signal.
The function can be limited so that the flow will not be
higher or lower than the preset max. and min. permissible
values respectively.
8.3.1.4 Slave Control
The flow is constantly regulated to be the same from the
one fan as from the other fan. If one fan is pressure-controlled or demand-controlled, the other one can be controlled as a slave to generate the same airflow.
The performance of the fan controlled as a slave can be
restricted if its maximum flow is set to a lower airflow rate.
Both fans cannot be controlled as slaves. If both are
selected by mistake, the extract air fan will be forced to
operate in the flow regulation mode.

8.3.3 Boosting
The airflow is regulated between two flows in response

Boosting can be used, for example, in assembly halls,
where a higher rate of air change is needed under fullload conditions.
The function is activated only when the unit fans operate
at high speed.
On a 0-10 V DC signal, the fans are gradually accelerated
from the unit’s initial high speed setting to its initial max
speed setting. On a max input 10 V DC signal, the unit
fans operate at max speed.
The function must be activated separately for the supply

8.6 Heating
8.6.1 Heat exchanger
8.6.1.1 Defrosting the rotary heat exchanger
In environments where the extract air can occasionally be humid, the defrosting function can be activated to protect the heat exchanger from frosting.
The function continuously monitors the condition
of the heat exchanger rotor to prevent condensate
from freezing in the rotor passages and clogging
them.
The function requires a separate pressure transducer
(preset for heat exchanger defrosting) wired to the control
unit inputs for external BUS communication and connected by hoses to the pressure measuring tappings of the
unit.
See special installation instruction for the TBLZ-1-23-aa
Pressure sensor.
The pressure drop across the rotor must then be calibrated
to establish a reference pressure drop for monitoring purposes. See 6.4.3 Calibration - Heat exchanger.
When the function is activated the pressure drop across
the heat exchanger is continuously measured and the
reading is compared with the calibration reading.
If the pressure drop exceeds the preset limit value, a
defrosting sequence is carried out. This involves, decreasing the rotor speed to approx. 0.5 rpm to allow warm
extract air to melt possible frost.
The defrosting sequence will be cancelled when the pressure drop has fallen to half the limit value. The defrosting
operates for a max permissible period of 30 minutes.
If the pressure drop has not decreased within that max
permissible period after six tries during a 24-hour period,
an alarm will be initiated.
Note that the heat exchanger performs less efficiently
while defrosting is in progress and that the supply air temperature will decrease downstream of the heat exchanger.

8.6.1.2 Exhaust air regulation, rotary heat
exchanger
The exhaust air regulation function can be used
whenever the exhaust air temperature is not permitted to be below a predetermined value.
The function controls the heat exchanger rotor speed
(efficiency) in order to limit the exhaust air temperature
to the required value. The function decelerates the heat
exchanger rotor speed from the current level, until the
exhaust air temperature drops to the preset min. permissible setting.

8.5.3 Heating BOOST
Heating boost means that the air handling unit, operating in the normal flow regulation mode, increases both
the supply airflow and the extract airflow in order to carry
more heat into the premises.
The fans are allowed to work in the range between current flows (low speed, high speed) and preset max speed
flow.
The function only works if the air handling unit is operating in the extract air regulation mode. If demand control
or boost is selected in combination with heating boost,
the flow is controlled by the function that transmits the
highest output signal to the fans.
This function cannot be combined with pressure regulation.
The flow increase starts steplessly when there is a difference of 2-10°C (3°C is factory preset) to preset max supply
air temperature. When max supply air temperature has
been reached, the unit runs at preset max flow (For particulars of how to set the max flow, see Section 6.3.2).

8.7 Cooling
8.7.1 Operation
Activate the cooling function.
8.7.2 Cooling Regulation
CoolDX -Economy (without heat exchanger)
Used when the CoolDX cooling unit is connected via bus
cable.
Both cooling relays of the air handling unit operate in parallel
with each relay on the IQnomic plus module in the CoolDX
cooling unit.
CoolDX - Comfort
Used when the CoolDX cooling unit is connected via bus
cable. The heat exchanger in the GOLD unit operates in
sequence with the cooling unit to even out the supply air temperature. Important! Requires an extra outdoor temperature
sensor.
Use the TBLZ-1-30 accessory for mounting an outdoor air
temperature sensor in the ductwork upstream of the CoolDX.
Use the TBLZ-1-2 4/5 accessory for installing the outdoor air
temperature sensor outdoors.
COOL DXS
For use when the COOL DXS cooling unit is connected via
a bus cable. The COOL DXS operates downstream of the
heat exchanger in the GOLD air handling unit.
Stepless 0-10 V DC
Used when variable cooling control is connected. The air handling unit cooling controller modulates a 0-10 V DC signal that
is linear with the cooling load (control unit terminals 42-43).
Both the cooling relays of the unit operate in parallel with the
signal and are energized when the cooling signal exceeds 0.5
V DC and are de-energized when the signal drops below 0.2
V DC.
The output for cooling relay 1 is connected to terminals 7-8
and for cooling relay 2 to terminals 9-10.
Stepless 10-0 V DC
Same as above, but the control signal is inverted where a 10 V
output signal means a 0 % cooling load.
On/off, 1 Step
Used if cooling in one step is connected. The air handling
unit’s cooling controller regulates the cooling load at 0-100
%. Cooling relays 1 and 2 are energized when the cooling
load exceeds 5 % and are de-energized when the cooling load
is less than 2 %.
The output contact for 0-10 V DC control signals (terminals
42-43) operates in parallel with the 0-100 % cooling demand
and can be used for indicating the cooling demand, for
instance.

On/off, 2 steps
Used when cooling in 2 steps is connected. The air handling
unit’s cooling controller regulates the cooling load at 0-100 %.
Cooling relay 1 is energized when the cooling load exceeds 5
% and is de-energized when the cooling load is less than 2 %.
Cooling relay 2 is energized when the cooling load exceeds 55
% and is de-energized when the cooling load is less than 50
%.
The 0-10 V DC control signal output (terminals 42-43) operates in parallel with the 0-100 % cooling demand and can be
used for indicating the cooling demand, for instance.
On/off, 3 Steps - Binary
Used when cooling with two inputs controlled with three
binary steps is connected. The cooling controller of the unit
regulates the cooling demand at 0-100 %.
On an increasing cooling load:
Cooling relay 1 is energized when the cooling load is
above 5 % and is de-energised when the cooling load is
between 40-70 %. Cooling relay 2 is energized when the
cooling load is above 40 %. Cooling relay 1 is energized
again (together with cooling relay 2) when the cooling
load is above 70%.
On a decreasing cooling load:
Cooling relay 1 drops when cooling load is below 60 %, it is
energized again when cooling load is below 30 % and drops
again when cooling load is below 2 %. Cooling relay 2 drops
when cooling load is below 30 %.
The output for 0-10 V DC control signals (terminals 42-43)
operates in parallel with the 0-100 % cooling load and can be
used for indicating the cooling demand, for instance.

8.7.3 Periodic Operation
Can be selected to run pumps if cooling relay 1 and/or 2
are used.
The exercising mode can be selected for “pump, pump +
valve” or “valve” only (0 - 10 V output). The pumps are
exercised 2 minutes per day if this is activated.
8.7.4 Regulation Speed
The required delay period between the various cooling
steps can be set.
This is done so that a compressor, for instance, will have
time generate required cooling capacity before the next
cooling step is switched in.
This applies to changeover from step 1 to step 2 and from
step 2 to step 3; and only on an increasing cooling load.
8.7.5 Outdoor Temperature Limit
Provision is available for setting an outdoor temperature-related blocking function in 3 steps. If the outdoor
temperature is below each step limit, the function of the
cooling relays will be blocked.
This function also restricts the 0-10 V output signal to
transmission in steps.
Step 1 maximises the output signal to 2.5 V, step 2 to 5.0
V and step 3 to 7.5 V.
8.7.6 Restart Time
The time should be set in such a way that it follows the
recommendations of the cooling machine supplier for the
number of starts per hour.
The restart time is calculated from the time when a relay is
energized to when it is allowed to be energized again.
The 0-10 V signal is delayed during the same period.
8.7.7 Cooling Min Air Flow
In order for the cooling function to operate the supply air
and extract air airflows must be greater than their respective limit values (preset at USER LEVEL under FLOW/PRESSURE).
The cooling min flow function can be blocked by setting
both flow limits to 0.
8.7.9 Cooling BOOST
Cooling BOOST means that the supply air and extract air
airflows are increased to convey more cooling energy to
the premises.
Cooling BOOST cannot be combined with pressure regulation.
The flow increase takes place between current flow and
preset max flow.
The function can be selected in three variants as follows:
Comfort
The cooling outputs are activated if there is a cooling load.
When the cooling function is active and the temperature
in the supply air drops toward the preset SA min temperature, the flow will steplessly increase.
The GOLD runs at preset max flow when the supply air
temperature is same as the min. temperature.
Economy
Cooling BOOST Economy first uses a higher airflow to cool
the premises, before a start signal is transmitted to the
cooling machines.
The function can also operate without the cooling function being activated.
On a cooling load, the flows are slowly increased up to
preset maximum flow. When the flows are up to max and
if a cooing load is still present, the output contacts for
cooling are activated.
The cooling boost function requires an outdoor air temperature of at least 2 °C lower than the extract air temperature for it to be activated. Normal cooling operation is
activated if the temperature difference is too small.
Sequence
The cooling BOOST Sequence is used if a cooling machine
is sized for a higher than normal cooling flow.
If there is a cooling load, the flow is increased up to the
preset max flow before the cooling function is activated.
The cooling function is delayed 1 minute after the airflow
is increased.
The cooling boost sequence is blocked if no cooling function has been selected.
8.7.8 Neutral Zone
The neutral zone prevents the cooling and heating systems
from counteracting each other.
Preset neutral zone is added to the setpoint for heating
and the sum of these provides the setpoint for cooling.

GB.GOLDSK509.091101
8.8 Humidity
Dehumidification control
The dehumidification function controls the moisture in the
supply air duct by switching in and switching out a cooling coil
and a postheating coil.
The function requires that a cooling coil be mounted upstream of
a postheating coil in the supply air duct, see the example to the
right.
The TBLZ-1-31-1 moisture sensor is mounted in the supply air
duct and its cable is connected to the appropriate terminal on
the GOLD unit.
Cooling energy is emitted to condense the moisture in the supply
air flow, which then is heated to the desired supply air temperature. This causes a reduction in the moisture content of the
supply air.
The cooling unit used must be sized so that the temperature of
the supply air will be below the dew point, otherwise no condensation will arise and no dehumidification will occur.

9 AUTOMATIC FUNCTIONS
9.1 General
The GOLD has a number of automatic functions. The operation
of the unit is influenced when certain functions are activated.
9.1.1 Starting Sequence
The GOLD has a starting sequence with factory-preset time delay
between every step as follows:
1. The damper relay is energized and opens the shut-off damper
(if installed).
Time delay: 30 seconds.
2. The extract air fan starts (not applicable if only GOLD SD
supply air handling units are installed) and the heat exchanger
is controlled to provide max. heat recovery (Not applicable to
GOLD SD units without heat exchanger). Additional heating (if
installed) is activated to generate 40% of its max capacity.
Time delay: 90 seconds.
3. The supply air fan starts (not applicable if only GOLD SD
extract air handling units are installed)
Time delay: 180 seconds (from the time when the extract air fan
has started).
4. The temperature regulation function begins according to its
regular settings.
The starting sequence prevents the extract air fan from starting if
the shut-off damper is closed. By starting the extract air fan first,
and the heat exchanger as well, the system also avoids chilling
the premises with cool supply air under cold weather conditions.
9.1.2 Cooling Recovery
Cooling energy recovery is an automatic function that helps the
air handling unit utilize the relative “cooling energy” that may be
present indoors if cooling is required and the outdoor temperature is high.
The heat exchanger rotates at max. speed and in this way recovers the relative cooling energy or chilliness in the extract air.
The conditions for this function to be activated are that there is a
cooling demand and that the outdoor temperature is 1 °C higher
than the extract air. The function is switched out when the cooling load ceases to exist or when the outdoor temperature is the
same as that of the extract air.
The text COOLING RECOVERY is shown in the hand-held micro
terminal.
9.1.3 Zero Point Calibration
The pressure transducer of the unit is automatically calibrated.
This calibration is carried out 3 minutes after the unit has been
stopped.
The text ZERO PT CALIBR is shown in the hand-held micro terminal.
The fans cannot start while calibration is in progres
9.1.4 Anti-frost Monitoring Function – Air Heater for
Hot Water
The anti frost monitoring function is always active if the air
heater for hot water connected has been supplied by Swegon.
The function activates a heating device that maintains 13 °C in
the coil while the air handling unit is in operation and 25 °C in
the coil when the unit is stopped. An alarm is initiated and the
unit is stopped if the temperature sensor senses a temperature
below 7 °C.
s.
9.1.5 Additional cooling – Electric Air Heater
The fans continue to operate at min speed for 3 minutes after
the air handling unit has been stopped to cool the electric heating elements if the electric air heater has been operating.
The text ADD COOLING appears in the hand-held micro terminal.
9.1.6 Reduction in output, electric air heater
A min. permissible air velocity of 1.5 m/s is required for preventing the electric heating elements from becoming overheated
when they are generating full heating output.
If the air handling unit supply airflow drops below the value
that corresponds to an air velocity of 1.5 m/s across the heat
exchanger the heating output of the air heater will be automatically reduced.
The text REDUCTION IN OUTPUT appears in the hand-held micro
terminal.
9.1.7 Additional running - Heat Exchanger
The rotary heat exchanger automatically continues to rotate ca 1
minute after the air handling unit has been stopped.
It takes a little time for the fans to stop rotating after a stop order
has been entered in the micro terminal. This prevents the admis-
sion of cool supply air into the premises.
9.1.8 Density-corrected Airflow
The density of the air is different at different temperatures. This
means that a specific volume of air will change at different air
densities.
The GOLD automatically corrects this, so that correct air volume
is always obtained.
The control equipment always shows the corrected airflow.
9.1.9 Purging Operation
Purging is an automatic function that prevents the rotary
heat exchanger from standing still in the same position
for a longer period when no heating is necessary.
Purging operation is activated when the unit is operating but the
heat exchanger rotor is not rotating. The heat exchanger rotor
then rotates for 10 seconds every 10 minutes to purge its sur-
faces clean of impurities.
9.1.10 Carry-over Control
Whenever the fans generate low airflows, the speed
of the rotary heat exchanger is reduced to an appropriate level for correct purging airflow through the heat
exchanger.
9.1.11 Calculaton of the efficiency of the rotary
heat exchanger
The efficiency is calculated and displayed (0 – 100%).
9.1.12 Pump control for the coil heat exchanger
The pump of the pipework package starts when
heat recovery is needed.
If heat recovery is not needed for more than 24
hours, the pump is exercised once a day.

9.1.13 Anti-frosting protection for the
plate/coil heat exchanger
In cold weather, and if the extract air is humid, there is risk
of frosting in plate/coil heat exchangers. The GOLD PX/CX
is equipped with anti-frosting protection.
GOLD PX (plate heat exchanger)
The temperature inside the heat exchanger’s ”cold
corner” and the humidity in the extract air are measured.
Taking the humidity into consideration, the control system
calculates the lowest permissible temperature without risk
of frosting inside the heat exchanger. The by-pass damper
is then controlled to prevent the temperature from dropping below this limit.
GB.GOLDSK509.091101
GOLD CX (coil heat exchanger) and
GOLD SD with coil heat exchanger
The temperature of the liquid circulated to the extract air
coil and the humidity in the extract air are measured.
Taking the humidity into consideration, the control system
calculates the lowest permissible temperature without risk
of frosting inside the coil.
The valve in the pipework package is then controlled to
prevent the temperature from dropping below this limit.

12 ALARM SETTINGS
12.1 Fire Alarms
EXTERNAL FIRE ALARM
Inputs 54 and 55 are used for external fire protection equipment.
The resetting of alarms can be selected to occur manually or automatically.
INTERNAL FIRE ALARM
The air handling unit’s internal temperature sensors serve as fire
protection thermostats. An alarm is initiated if the supply air temperature sensor registers more than 70 °C or when the extract air
temperature sensor registers more than 50 °C.
If an external Extract air/Room temperature sensor is connected and
activated, this works parallel with the extract air temperature sensor
of the unit.
FANS IN THE EVENT OF A FIRE
The fans in the air handling unit can be used for evacuating gases,
etc.
The activated function works together with the External fire/smoke
function or Internal fire alarm.
If the air handling unit is idle, the pre-selected fans will start up
regardless of whether External Stop or Manual Stop has been activated in the hand-held micro terminal.
The damper relay in the air handling unit is energized and the
operating relay drops.
The dampers pre-selected for service in the event of a fire, should
be wired to the damper relay (control unit terminals 22-24) and
these dampers will open.
The dampers that are meant to close in the event of a fire, should
be wired to the in-operation relay (control unit terminals 19-21) and
these dampers will close.
FAN SPEED IN THE EVENT OF FIRE
Will be activated automatically if the fans have been activated in
event of fire (see above), and make it possible to restrict the max
speed of the fans.

16 MAINTENANCE
Warning
Before carrying out any work, make sure that the
power supply to the unit has been isolated.
16.1 Filter Change
The filters should be changed when the filter alarm has been
activated.
Order new filters from Swegon or its representative!
State the size of the GOLD unit and whether the change involves
one or two air directions.
16.1.1 To remove the Filters
Pull out the handles (A) to free the filters from the filter holder.
Withdraw the filters.
It is advisable to clean inside the filter space while the filters are
gone.
16.1.2 To fit new filters
Insert the filters into the filter holder. At the same time, stretch
out the filter bags, so that they will not get caught, hurt or
become folded.
Insert the filters as far as possible into the unit and press lightly
on the filter frames, so that they will fit tightly.
Push in the handles (A) so that the filters are clamped in place in
the filter holder.
Carry out a filter calibration as described in Section 6.4.2.
16.2 Cleaning and Inspection
16.2.1 General
Clean the interior of the air handling unit as the need arises.
Inspect the air handling unit thoroughly at the same time that
you replace the filters or at least twice a year.
16.2.2 Filter Space
Cleaning is most appropriate when you change the filters.
16.2.3 Heat exchangers
Check at least twice a year whether cleaning is necessary.
The cleaning work is carried out from the filter space.
Rotary heat exchanger
The heat exchanger should preferably be cleaned by vacuum
cleaning with a soft nozzle to prevent damaging the air passages
in the rotor.
Turn the rotor by hand to enable you to vacuum clean its entire
surface.
If the heat exchanger is substantially fouled, it can be blown
clean with compressed air.
If necessary, the heat exchanger can be withdrawn from the unit
casing and washed with degreasing solvent. Only service personnel trained by Swegon shall be permitted to use this cleaning
method.
FABRIC SEAL
Lift up the fabric seal and inspect its underside. Clean if needed
by brushing or vacuum cleaning.
If the fabric seal is worn or substantially fouled, it should be
replaced. Do not lubricate it!
BELT TENSION
Replace the drive belt if it feels loose or worn and slightly slips
if it meets resistance. Contact service personnel trained by
Swegon!
Plate heat exchanger
Always clean against the regular direction of airflow.
Cleaning shall only be done by blowing with compressed air,
vacuum cleaning with a soft nozzle or wet cleaning with water
and/or solvent. Before you begin cleaning, cover adjacent functional sections to protect them.
If cleaning solvent is used, do not use solvent that will corrode
aluminium or copper. Swegon’s cleaning agent is recommended.
This cleaning agent is sold by Swegon Service.
Inspect the condensate drain to make sure that it isn’t clogged.
The by-pass and shut-off dampers do not require maintenance.
Coil heat exchanger
Make sure that the coils are purged of air. If a droplet eliminator
is fitted, remove it and flush it clean with water.
Always clean against the regular direction of airflow.
Cleaning shall only be done by blowing with compressed air,
vacuum cleaning with a soft nozzle or wet cleaning with water
and/or solvent. Before you begin cleaning, cover adjacent functional sections to protect them.
If cleaning solvent is used, do not use solvent that will corrode
aluminium or copper. Swegon’s cleaning agent is recommended.
This cleaning agent is sold by Swegon Service.
While cleaning, check the content of glycol in the water and the
condition of the coil for tightness. Also check that the condensate drain is not clogged.
16.2.4 Fans and Fan Space
Inspect and clean the fan impellers to remove possible dirt
deposits.
Check the impeller to make sure that it is not out of balance.
Clean or brush off the fan motor. It can also be cleaned by
carefully wiping it with a damp cloth that has been dipped in a
solution of water and dishwashing detergent.
Clean the fan space, if needed.
16.3 Performance Checks
General performance checks should be carried out in conjunction with filter change or at least once a year.
It is then appropriate to compare the current performance values
of the unit with the Commissioning Record. Eventual deviations
should be remedied.
We reserve the right to alter specifications without notice.

GB.GOLDSK509.091101
16.4 To change the pump, pipework package, GOLD CX, sizes 35-80
Before the pump can be replaced, the coils will have to be partially emptied.
An electrician or a duly qualified person skilled in electrical installations is required to disconnect and connect the power supply
cable to the pump.
To empty the coils:
It isn’t necessary to completely empty the system; it will be sufficient to empty to a level just below the pump.
For the variants in which the pump is arranged above the expansion vessel, the system can be emptied from the header by the
expansion vessel.
For the other variants, the venting or drain nipples on the lower
coils should be used for emptying.
Open the venting valve on the upper coil as well.
To remove the old pump:
Remove the insulation material around the pump and make note
of the direction of liquid flow.
Disconnect the electrical connections from the pump.
Remove the bolts on the pump’s flange connections and remove
the pump.
Remove the old gaskets and clean the surfaces where they have
been seated.
To mount the new pump:
Fit the new gaskets.
Check the direction of flow of the new pump and mount it so
that the direction of liquid flow will be the same as before.
Tighten the bolts on the pump’s flange connections.
Wire the electrical connections to the pump.
To refill the coils:
When refilling, fill with glycol of the type used in brine systems;
not the type used in motor vehicles!
always 30% from the factory.
The total volume of glycol/water is 122 litres in size 35/40,
176 litres in size 50/60 and 231 litres in size 70/80 units.
Open the valve on the header by the expansion vessel and connect the filling hose.
Start the external filling pump and refill the coils. The filling
pump should hold a pressure of approx 1 bar .
Use the venting valves to vent both the upper and lower coils.
Close the lower venting valve when liquid, free of air bubbles,
flows out.
Close the upper venting valve when liquid, free of air bubbles,
flows out.
Start the internal circulation pump and make sure that the direc-
tion of rotation is correct.
The green LED on the terminal box of the pump shall be lit while
the pump is operating. If the red LED is lit, the pump impeller is
rotating in the wrong direction.
Operate the unit for approx. 10 minutes, then vent both the upper and lower coils.
Close the filling valve and switch off the pump.
Remove the hoses and re-insulate the pump.
Operate the unit for approx. 1 week, then vent both the upper
and lower coils again.
The glycol content is

the hand-held micro terminal.
Fire alarms and frost alarms are shown in all the menu
images. Other alarms are only shown if you are in the
Main menu.
Active, but time-delayed alarms can be viewed quickly at
USER LEVEL under ALARMS. The 10 most recently initiated
alarms can also be read in this menu.
A fault can be traced by examining the function or function section indicated in the alarm text.
Faults can also be traced via the READINGS menu or the
MANUAL TEST menu at Installation level.
If the fault cannot immediately be remedied:
Consider whether the air handling unit can continue to
operate until the fault has been remedied. Choose to
block the alarm and/or to change it from STOP to OPERATION (See Section 12, Alarm settings).
17.1.1 A and B-alarms
Type A alarms transmit an alarm signal to the alarm relay A
output (control unit terminals 15-16).
Type B alarms transmit an alarm signal to the alarm relay B
output (control unit terminals 17-18).
From these terminals, alarms can be forwarded with different priority.
The alarm relays can be selected to have normally open or
normally closed function.
17.1.2 Resetting of alarms
Alarms that require manual resetting can be reset from
the hand-held micro terminal. Select RESET in the current
alarm menu.
