1 GENERAL
1.1 Range of Application
The GOLD LP is a complete air handling unit with built-in
control equipment. The air handling units are designed for
comfort ventilation and can be utilised in buildings such as
offices, schools, day nurseries, public buildings, shops and
residential buildings.
The GOLD LP units are one-piece air handling units. If
supplementary function sections such as dampers and air
coolers are required, they must be installed in the ductwork.
In order to fully obtain all the benefits the GOLD LP has to
offer, it is important keep in mind the air handling unit’s
special characteristics in conjunction with designing the
project, installing the unit, adjusting it and operating the
system.
The unit must be installed indoors.
Important!
Always read the safety precautions in Section 2 that
explain the risks involved in running the unit and
designate who shall be permitted to operate and
service the unit, and carefully follow the installation
instructions provided in each paragraph.

2 SAFETY PRECAUTIONS
All staff concerned must acquaint themselves with these
instructions before beginning any work on the unit. Any
damages to the unit or parts of it due to 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 a qualified electrician or 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
On the GOLD LP one-piece unit, the safety isolating switch
is externally positioned on the electrical equipment cubicle.
The air handling unit must normally be started and
stopped from the hand-held micro terminal; not by
switching the safety isolating switch on and off.
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 air handling unit has been
switched off.
Risk areas with moving parts
Typical moving parts are fan impellers and drive pulleys of
the rotary heat exchanger.
Inspection panels can only be opened using a special key,
they therefore function as safety guards for fans and the
heat exchanger. If the ducts are not connected to the fan
outlets, the outlets must be fitted with a safety guard
(wire mesh screen).
Warning
The inspection panels 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 panel.
The air pressure inside the fan section is positive,
which means that the door can fly open.
2.3 Safety Guards
The lockable inspection panels serve as a safety guard for
the fans/heat exchanger.
The cover over the power supply unit in the electric equipment cubicle serves as a safety guard for this unit.
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.
All the inspection panels must be closed and the
cover of the electrical equipment cubicle must be
fastened while the air handling unit is operating.

3 INSTALLATION
See the specific installation instructions.
4 COMMISSIONING
4.1 General
Sequence for commissioning:
1. Check that there are no foreign objects in unit, ducting system
or functional sections.
2. Turn the safety isolating switch to the ON position (I).
3. Select the language desired, if you have not already done so.
See Section 6.2 or 14.1.
4. The unit has factory settings which make it ready to use. See
Section 21.2 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
5-16.
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.
5. 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
4.2.
6. Finish off with a filter calibration as described in Section 7.4.2.

4.2 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.
4.2.1 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.
4.2.2 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.
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.
qp = design airflow (l/s)
qm = airflow reading (l/s)
q
m
K (Ratio) =
q
p
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 adjustments.

4.3 To Adjust the Pressure Balance
4.3.1 General
There should be a certain degree of negative pressure in
the extract air section so that the direction of air leakage
through the heat exchanger and the function of the purging sector will be correct. This ensures that extract air will
not be transferred to the supply air.
The pressure balance in the unit should be adjusted when
the ventilation system has been fully installed and the
airflows discharged from all the air diffusers and registers
have been adjusted, and when the supply air and extract
airflows are as they should be while the air handling unit is
operating normally.
4.3.2 To Ensure the Correct Leakage Direction
The pressure balance in the AHU is adjusted by repositioning a commissioning plate mounted in the extract air inlet.
The commissioning plate is supplied separately and should
be fitted by the fitter when the extract air duct is connected. See illustration.
Connect a pressure gauge to the pressure measurement
tappings of the air handling unit. The AHU has four pressure measurement tappings. The two tappings closest
to the extract air duct should be used. The blue pressure
measurement tapping is used for measuring the negative
pressure in the extract air section and the white pressure
measurement tapping is used for measuring the negative
pressure in the supply air section.
The pressure measurement tappings are situated by the
junction hood.
Note that both pressure measurement tappings are used
for measuring negative pressure.
MEASURED VALUES
The negative pressure in the extract air section should be
greater or the same as the negative pressure in the supply
air section.
If the negative pressure in the extract air section is the
same or up to 20 Pa greater than the negative pressure in
the supply air section, then you have finished commissioning the unit.
DEVIATIONS
If the negative pressure in the extract air section is less
than that in the supply air section, then you must carry out
the following adjustment:
1. Stop the air handling unit, open the inspection door to
access the extract air filter.
Blank off an appropriate number of holes in the commissioning plate using the plastic plugs supplied.
3. Close the inspection door and restart the AHU.
4. Measure the pressures.
Repeat this procedure until the negative pressure in the
extract air section is just as great or up to 20 Pa greater
than the negative pressure in the supply air section
(0–20 Pa).

Commissioning plate
5. If the negative pressure in the extract air section is
greater than 20 Pa compared with the supply air section, although the commissioning plate is dismantled,
the leakage and purging air flow will be greater than
anticipated. This means that the actual extract air flow
will deviate from the preset extract airflow. The deviation increases as the difference in pressure increases.

tions for flow/pressure are described in detail.
7.2.1 Readings
Used for performance checks.
7.2.2 Settings
The functions selected at INSTALLATION LEVEL and the
min. and max. airflows of each unit size (see the table
below) determine which values can be set.
Values for airflow (l/s, m3/s, m3/h), pressure (Pa) or input
signal strength (%) can be preset depending on the function selected.
LOW SPEED
Must always be preset! The value for low fan speed cannot be higher than the value for high speed. Low speed
can be set to 0, which means that the fan is standing still.
HIGH SPEED
Must always be preset! The value or pressure for high fan
speed cannot be lower than the value for low fan speed.
MAX SPEED
Max speed is only appropriate for functions such as pressure regulation, Heating BOOST or Cooling BOOST. The
value for max fan speed cannot be lower than the value
for high fan speed.
MIN/MAX SPEED
Min/max fan speed is only appropriate for demand-controlled operation. The lowest and highest permissible
flows are preset for each of the fans. This means that the
fans will not operate outside these limits, regardless the
load.

7.3 Switch clock
Basic functions for the switch clock can be preset
at INSTALLATION LEVEL under FUNCTIONS/OPERATION and the values can be read and set at USER
LEVEL.
TIME/DATE
The current date and time can be set and adjusted whenever
required.
The switch clock automatically takes leap years into consideration.
Automatic changeover between summer time/winter time to EU
Standard has been preset.
This changeover function can be blocked at INSTALLATION LEVEL
under FUNCTIONS/OPERATION.
TIME CHANNEL
Times and days can be set when the unit is to run at high speed,
low speed or be stopped.
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.
7.4 Filters
(and anti-frosting function of rotary heat exchanger)
There are two types of filter monitoring:
Calculated filter monitoring (preset at factory) monitors the fan’s
speed increase conditional on the degree of fouling in the filter.
The calibration involves taking airflow and fan speed readings.
An alarm is initiated when the fan speed has increased by 10%
above the preset alarm limit.
Filter monitoring with a pressure sensor (accessory) measures
the pressure drop across the filter. The alarm limit is preset in Pa.
7.4.1 Readings
When reading the filter status, the first value shows current value
and the second value shows current alarm limit.
7.4.2 Calibration - Filters
The filters should be calibrated for the first time in conjunction
with commissioning, when the duct system, air devices and
eventual adjustment plates have been fitted and adjusted; after
that every time the filter media are changed.
Calibration should be activated for both the supply air and the
extract air if both filters are changed or for only for one airflow
direction if only one filter has been changed.
When filter calibration has been activated, the unit runs at high
speed for about 3 minutes.
After the filter has been calibrated, a speed increase of 10%, or
a pressure rise (= fouling of the filters) of 100 Pa is permissible,
after which an alarm is initiated indicating a fouled filter.
The alarm limit can be changed at INSTALLATION LEVEL under
ALARM SETTINGS.
7.4.3 Calibration - Rotary Heat Exchanger
If the anti-frosting function accessory for heat exchanger is installed (see 9.6.1.1) calibration can be selected from this menu.
When calibration R-HX is activated the fans are accelerated to
high speed for about 3 minutes.

FUNCTIONS

9.1 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.
9.2 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.
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.
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.
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.
Control sequence for Extract air regulation:
1. The temperature efficiency of the air handling unit’s
heat exchanger is modulated to provide max. heat
recovery.
2. After that, the re-heating coil, if installed, will begin
to generate heat.

FRT-reglering 19.2.1.1 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.

The setting range for the breakpoint and EA/SA differential is limited by the Min. and Max. settings at INSTALLA-
TION LEVEL under HAND TERMINAL.
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
TEMPERATURE/SETTINGS:
Value Setting Factory

Y1 10-40 °C 20 °C
Y2 10-40 °C 18 °C
Y3 10-40 °C 14 °C
The setpoint displacement and summer night cooling
functions can also affect the preset temperatures.
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).
Factory setting means:
If the extract air temperature is below 20 °C (breakpoint),
the supply air temperature setpoint will be automatically
regulated to be 2 °C (EA/SA differential) lower.
If the extract air temperature is above 20 °C, the supply
air temperature setpoint will follow the curve according to
Step 1.

9.2.1.2 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.
9.2.1.3 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 an adequate representative extract air temperature readings,
an external room temperature sensor can be installed and
wired to the control unit’s connection marked “Internal
Bus-1”.
The following settings can be entered at USER LEVEL under TEMPERATURE/SETTINGS:

9.2.2 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).
See the chart to the right.
It is possible to set negative summer compensation.

9.2.3 Summer Night Cooling
The lower temperature at night is utilised 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 minimised, thus offering
savings. If no cooling unit is installed, a certain cooling
effect will still be realised.
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.
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.
The function starts once per set time period.

9.2.4 Intermittent Night-time Heating
The unit is utilised to heat the premises when it is normally
stopped by the switch clock.
The function requires that an external room sensor is
connected and that the air handling unit is provided with
air heater for reheating the air. Connect the TBLZ-1-24-2
Room sensor by means of the modular cable supplied, to
an optional connection marked Internal BUS 1. The capacity of the function will be best if the GOLD is provided with
a recirculation damper (not Swegon supply) and a shut-off
damper for outdoor air and 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.
At the same time, the damper in the air recirculation section, if included, will open.
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.)
