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.
See the chart to the right.
The steps, breakpoint and EA/SA differential plotted in
the curve can be changed at USER LEVEL under TEMPERATURE/SETTINGS.

If the extract air temperature is below 22 °C (breakpoint),
the supply air temperature setpoint will be automatically
regulated to be 3 °C (EA/SA differential) lower.
If the extract air temperature is above 22 °C, the supply air
temperature setpoint will be constantly 19 °C (step 2).
ERS regulation 2
ERS REGULATION 2
This is used when special needs and conditions are such
that the factory preset ERS regulation 1 curve cannot provide the results required. Conditional on which settings are
made, it may be necessary to install a post-heating coil.
An individually adapted curve regulates the relationship
between the supply air and extract air temperature.
See the chart to the right.
The following settings are possible at USER LEVEL under

Y = Setpoint supply air temperature °C
X = Extract air temperature °C
Breakpoints according to factory setting means:
If the extract air temperature is below 15 °C (X1) the setpoint for supply air temperature is constant 20 °C (Y1).
If the extract air temperature is 20 °C (X2) the supply air
temperature set point will be 18 °C (Y2).
If the extract air temperature is above 22 °C (X3), the
supply air temperature setpoint will be constantly 14 °C
(Y3).

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.
It is possible to set negative summer compensation.
Settings:

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.
