3. Filter Calibration
All the filters should be calibrated when the fans are started up
for the first time and when the duct system, air terminals and
commissioning plates, if required, have been installed and commissioned.
After that every time filters are replaced. Calibration should then
be activated for the filter or filters that are new. Relevant filters
are the Supply air prefilter, Extract air pre-filter, Supply air AHU
filter, Extract air AHU filter, SA and EA AHU filter and Supply air
end filter.
When filter calibration is activated, the unit attempts to achieve
the set max. flow/pressure (depending on the type of regulation). In order for the calibration to start, a stable air flow must
be achieved. Filter calibration continues until the right conditions occur or for max. 15 minutes.
An indication of ongoing filter calibration can be sent via communication and/or I/O module (digital output signal).

When the flow has been stable (variation of less than +/- 3%)
for 30 seconds (adjustable), the calibration starts.
The calibration continues for three minutes.

Progress
Start
The calibration fails if:
The flow does not remain stable for 12 minutes.
The filter pressure drop is not greater than 5 Pa.
The flow does not exceed the min. flow.
After the filters have been calibrated, a pressure rise of up to 100
Pa is permissible (as the filters arrest impurities) after which an
alarm indicating fouled filter is initiated. The alarm limit can be
changed under Installation, Functions, Filters.
The filter function must be activated (see Section 4.5) in order to
make it possible to enable filter calibration and alarm functions
of the end filter and pre-filter in GOLD SD supply air and extract
air handling units.

Airflow
All the relevant values can be read here. Used for performance
checks.
Reading of internal leakage rotary heat exchanger
The internal leakage is read and reported in accordance with EN
16798-3.
Status
OACF (Outdoor Air Correction Factor) is the relation between
outdoor air/supply air. It shall normally be between 1.0-1.1. The
value should not be below 1.0 as it indicates that the leakage
direction is incorrect (= return air).
EATR (Exhaust Air Transfer) shows the transfer of exhaust air to
supply air and is shown in %. The lowest possible displayed value
is 0.9, which means the transfer is <= 0.9%. Other values are
shown in step of whole percentages (1, 2, 3, etc.).

4.1.2 Operation level
Operation level
The functions selected and the min. and max. airflows of each
AHU size (see the table below) determine which values can be
set.
Depending on the function selected, flows can be set as follows
(l/s, m3/s, m3/h, cfm), pressure (Pa, psi, in.wc) or input signal
strength (%).
Low speed
Should always be preset. The value for low speed cannot be
higher than the value for high speed. Low speed can be set to 0,
which means that the AHU is idle.
High Speed
Should always be preset. The value or pressure for high speed
cannot be lower than the value for low speed.
Max. speed
Should always be preset. Used mainly for filter calibration. While
filter calibration is in progress, the max. speed setting should be
as high as the ventilation system permits without causing any
breakdown. Also used for the pressure regulation, boosting,
Heating Boost and Cooling Boost functions. The value for max
speed cannot be lower than the value for high speed.
Min. /Max. speed
Used for the demand control function (the previous section also
applies to max. speed). Preset the lowest and highest permissible
flows for each fan. This means that the fans will not operate
outside these limits, regardless the load.
Slave
The flow difference for any slave controlled fan can be set between the slave controlled fan and the other fan. The setting
occurs in a fixed flow difference and/or a percentage difference.

1) When adjusting the flow, round off the value to the nearest settable step.
2) If pressure regulation is used, the airflow can be regulated to zero, however this presupposes a certain static
pressure drop in the ducting (approx. 50 Pa).

4.1.3 Regulation mode
The regulation moden can be selected individually for the supply
air or the extract air respectively.
Regulation mode
Airflow
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, if air diffusers become blocked, etc.
A constant airflow is advantageous, since the airflow is always at
the level preset 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 to the occupants such as excessive sound.
Duct pressure
The airflow automatically varies to provide constant pressure in
the ducting. This type of regulation is therefore also called VAV
Regulation (Variable Air Volume).
Pressure regulation is used when e.g. damper operations
increase the air volume in sections of the ventilation system.
The duct pressure is measured by an external in-duct pressure
sensor which is connected to the control unit's BUS communication. The set point required (separate for low speed and high
speed) is preset in Pa.
The function can be limited so that the fan speed will not exceed
the preset max. values.
Demand
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 18-19. The required set point
is set as a percentage of the input signal or in ppm.
The function can be limited so that the flow will not be higher or
lower than the preset max. and min. values respectively.
Slave
Normally the flow is constantly regulated to the same value
as the other fan. If one fan is pressure-controlled or demandcontrolled, the other one can be controlled as a slave to generate
the same air flow.
The performance of the slave fan can be restricted if its maximum flow is set to a lower airflow rate.
It is also possible to set a flow difference between the slave controlled fan and the other fan. The setting occurs in a fixed flow
difference and/or a percentage difference. For example, this can
be used when there is a separate extract air fan and balanced
ventilation is wanted.
It is not possible to control both fans as slaves. If you select one
fan to operate as a slave, you lose the option to select the other
fan as a slave.

4.1.5 Set point displacement
The airflow is regulated between two flows in response to an
0-10 V DC input signal from an external signal, for example a potentiometer. The TBIQ-3-2 IQlogic+ module accessory is required.
Set point displacement
Set point displacement can be used e.g. in assembly halls, where
a higher rate of air change is needed under full-load conditions.
The function is activated only when the AHU fans operate at
high speed.
On a 0-10 V DC signal, the fans are gradually accelerated from
the AHU’s high speed setting to its max. speed setting. On a
max. input 10 V DC signal, the AHU fans operate at max. speed.
The function must be activated separately for the supply air fan
and for the extract air fan.

4.1.7 Air adjustment
The speed of the fans can be locked for up to 72 hours. When
the function is activated, the speed is locked at the current speed
of operation. This is practical when making airflow adjustments
in the duct system and air terminals. The desired period is preset,
but can be interrupted earlier by selecting Stop or by changing
the time setting to 0.

Air adjustment
We reserve the right to alter specifications without notice.
GB.GOLDSKFFI.240221
Outdoor air compensation of the airflow can be activated if you
want to change the airflow for specific outdoor air temperatures.
An individually adjusted curve regulates the ratio between the
airflow and the outdoor air temperature. The curve has four
adjustable breakpoints..
If the function is selected solely for low speed or high speed
operation, the curve will regulate only one of these. The airflow
for the operating case that has not been selected will then be
according to the preset set point for airflow/duct pressure.
In the flow regulation mode, the current set point for airflow is
changed. When pressure regulation is selected, the current set
point for pressure is changed. The function has no effect if the
airflow is demand-controlled.
The airflow change is expressed in the preset airflow unit and
pressure in Pa.

4.1.10 Automatic operation
Density-corrected airflow
The density of the air is different at different temperatures. This
means that a specific volume of air changes at various air densities. The AHU automatically corrects this, so that correct air
volume is always obtained.
The control equipment always displays the corrected airflow.
Pressure balance corrected extract airflow
The extract airflow is corrected by continuously measuring the
pressure balance across the rotary heat exchanger. The extract
airflow is guaranteed with consideration given to the air purging
and leakage air flow.

ERS Regulation 1
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 control is suitable for use when there is surplus heat in the
premises generated e.g. by machinery, lighting or people, and
the premises have supply air diffusers suitable for discharging air
below room temperature.
ERS Regulation 1
The control unit regulates the ratio between the supply air and

Supply air regulation
If the extract air temperature is between 15 °C (X1) and 20 °C
(X2), the supply air temperature set point is regulated from 20
°C (Y1) down to 18 °C (Y2) as shown in the curve.
Supply air regulation involves maintaining 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 this requires
the installation of an air heater for reheating, possibly an air
cooler as well.

Extract air regulation
Extract air control involves maintaining a constant temperature
in the extract air duct (the 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
an air heater for reheating; possibly a cooling coil as well.
The extract air temperature is measured by the air handling unit's
internal temperature sensor. If this internal temperature sensor
does not give an adequate representative extract air temperature
reading, an external room temperature sensor can be installed
and wired to the control unit’s communications BUS (optional

Seasonal controlled temperature regulation
Seasonal controlled temperature regulation makes it possible to
have two temperature regulation modes that alternate at preset
outdoor temperatures.
Seasonal controlled temperature regulation operates with the air
handling unit's internal temperature sensor, however for the best
performance we recommend external outdoor temperature sensor TBLZ-1-24-3; see separate installation instructions.
If the ordinary temperature and seasonal controlled temperature
regulation are to be of different types, these can be combined
freely, for example, ordinary temperature regulation = ERS 1 and
seasonal controlled temperature regulation = supply air.
In instances where the same type of ordinary temperature
regulation and seasonal controlled temperature regulation are
desired, this can be selected for supply air control and extract air
control. Values for seasonal controlled temperature regulation
can then be set independently of values for ordinary temperature
regulation.

temperature is 3 K (preset at factory) higher than the preset max.
supply air temperature.
Economy
Cooling Boost Economy initially uses a higher airflow to cool the
premises, before a start signal is transmitted to chillers.
The function can also operate without the cooling function
activated.
In the event of a cooling load, the airflows 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 function requires that the outdoor air temperature is at least
2 K lower than the extract air temperature for it to be activated.
The normal cooling function is activated if the temperature difference is too small.
Sequence
The Cooling Boost Sequence is used if a chiller is sized for a
higher cooling flow than normal flow.
If there is a cooling load, the flow is increased up to the preset
max. flow and the cooling function is activated afterwards.
The Cooling Boost Sequence is blocked if no cooling function
has been selected.

4.2.15 Intermittent night heat
The AHU is utilized for heating the premises when it is normally
stopped by timer.
Intermittent night heat
The function requires that an external room sensor is wired to
the control unit’s communication BUS (optional COM 1-3) and
that the AHU is fitted with an air heater for reheating the air. 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 set point. At the same time, the damper in the air
recirculation section opens, if one is installed.
If recirculation is in the Off position, the extract air fan is operating and the damper relay is open. The extract airflow setting can
be decreased to the air handling unit‘s min. flow.
Intermittent night heat does not affect any possible extra temperature zone (Xzone) which regulates according to its ordinary
set point if Intermittent night heat is in operation.
Conditions to be met for intermittent night-time heating to start:
• The AHU must be set to normal stop or extended
normal stop.
EXTRACT AIR
• The room temperature must be lower than the preset start
temperature.
• Summer night cooling has not been active during the day.
Conditions to be met so that Intermittent night heat will stop:
• The air handling unit is running at normal low/high speed or
external/manual stop has been activated.
SUPPLY AIR
• The room temperature exceeds the preset stop temperature.
• The alarm with preset stop priority trips.
(If needed, the air handling unit fans will continue to operate
to cool the electric air heater although other conditions for
stop have been met.)

4.2.16 Summer night cool
Summer night cool
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, it will not need to be
operated, thus offering savings. If no cooling unit is installed, a
certain cooling effect will still be achieved.
When the function is activated, the AHU fans operate at high
speed, with a supply air set point of 10 °C (factory setting) from
the preset time until the conditions necessary for stop are satisfied.
If the air handling unit is stopped for a period of time, test starts
can be implemented in order to check whether all conditions,
except heating demand, for summer night cooling have been
met. If the conditions have been met, summer night cooling can
be run. The start and stop dates of the period during which the
air handling unit will be stopped can be preset.
The set point for flow or pressure on the supply air and extract
air can be set. This then means that any outdoor compensation
does not affect summer night cooling.
An extra temperature zone (Xzone), if required, obtains the same
supply air set point if Summer night cool is in operation.
Conditions that must be met for Summer night cool to start at
the preset time:
• The time is between the preset start time and stop time.
• The outdoor air temperature shall be higher than the preset
value.
• The extract air temperature shall be higher than the preset
value.
• The extract air is at least 2 °C warmer than the outdoor air.
• Heating load has not been required between 12.00 and
23.59 hours (heating load for dehumidification is not registered as heating load).1)
• The air handling unit shall be running at low speed or be in
the normal stop operating mode.
• Intermittent night heat has not been active during the day.
Conditions that must be met for Summer night cool to stop:
• The time is not between the preset start time and stop time.
• The extract air temperature drops below the preset value.
• The outdoor temperature drops below the preset value.
• The extract air is less than 1 °C warmer than the outdoor air.
• The air handling unit is running at normal high speed or
external/manual stop has been activated.
The function starts once per preset time period.

4.3 Time and schedule
The built-in timer enables you to control the AHU's operating
mode/time. Certain other oversteering functions such as external
timer, communication, etc. affect the preset operating modes.
There are five different operating modes:
Total stop = The AHU is completely stopped, no internal automatic functions or external control commands can start the AHU.
Normal Stop = The AHU has stopped, however all the internal
and external automatic functions oversteer the stop.
Extended Normal Stop = The AHU has stopped, however all the
internal and external automatic functions, with exception of
Summer night cool, oversteer the stop.
Low speed = The AHU is running at the preset low speed setting.
High speed = The AHU is running at the preset high speed setting.
4.3.1 Time and date
The current date and time can be set and adjusted if needed. The
timer automatically takes leap years into consideration.
Time and

4.8.1 Fire alarms
Internal fire alarm
Alarm settings
If an external Extract air/Room temperature sensor is connected
and activated, this works parallel with the extract air temperature
sensor of the AHU.
Fire alarms
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 45 °C. Alarm limits are
possible to set.
External fire alarm 1 and 2
External fire alarm 1 (Terminals 6-7) and external fire alarm 2
(Terminals 8-9) are used for external fire-control equipment.
Alarm reset
The resetting of internal fire alarms as well as the external fire
alarms 1 and 2 can be individually selected to manual or automatic.
After cool
The After cool function for electric air heaters, COOL DX and/
or SMART Link DX can be individually activated, for internal fire
alarms as well as external fire alarms 1 and 2.
Fan operation at fire alarm
The fans of the air handling unit can be used for evacuating
smoke, etc. It is possible to individually select the type of fan
operation for each separate fire alarm.
If the AHU is idle, the fans selected start up (10-100%), irrespective of whether stop (all types) is activated.
The AHU’s damper relay is energized and the AHU’s operation
relay is de-energized.
Dampers used must be equipped with a spring return and be for
a 24 VAC supply voltage.
The damper that should be open in the event of fire shall be connected to the damper relay. Connect the damper to the control
unit’s terminals 28 and 30.
The damper that should be closed in the event of fire shall be
connected to the operation relay. Connect the damper to the
control unit’s terminals 26 and 30. A jumper is placed between
terminals 27 and 29.
Priority
The mutual priority of the internal and the external fire alarms
can be set. If automatic is selected, this means that the first input
to be activated is given priority.
Fire bypass in flow diagram
The fire bypass is shown on the hand-held terminal’s flow diagram when the function is activated. Fan operation for extract air
must be active for at least one of the fire alarms. Dampers switch
to fire bypass if any of the fire alarms are active and the extract
air fan is operational.

N.B.! This changes the function of the fans from supply
air to extract air and vice versa. GOLD RX size 004-120/
GOLD RX Top can be changed at the site. The other variants must not be changed from the factory setting.
For changes in fan position, check the filter class in the
supply and extract air. If the filter classes for the supply
and extract air are not equal, change the positions of
the filters. RX Top 004-012 and 025/030 has supply and
extract air filters in different dimensions, these must be
ordered. For RX Top 004-012 another commissioning
plate must also be ordered. For sizes 014-120 even the
supply and extract air fans can be in different sizes/capacity variant, which must be taken into account. The rating
plate shows the combinations of fan sizes and capacity
variants.
The fan position in the flow chart can be read and should be set
according to the AHU's actual configuration.

4.10.5 Automatic functions
Start up sequence
The air handling unit has a start up sequence with a factorypreset time delay between each step as follows:
1. The damper relay is energized and opens the shut-off damper
(if installed). The heat exchanger is controlled to max. heat
recovery (not the GOLD SD without heat exchanger). The
valve for reheating opens to 40% (if installed)
Time delay: 30 seconds.
2. The extract air fan starts in the current operating mode (not
for ventilation systems with GOLD SD supply air handling unit
only)
Time delay: 60 seconds.
3. The supply air fan starts (not for ventilation systems with
GOLD SD extract air handling unit only)
Time delay: 30 seconds.
4. The reheating function is ramped up or down depending on
the heating load. Ramp time: 180 seconds. After that the
heat exchanger is ramped up or down depending on the
heating load. Ramp time: 180 seconds.
The entire start up sequence can be followed in the dashboard
image.
The start up sequence prevents the extract air fan from starting
up if the shut-off damper is closed. By first starting up the extract
air fan and the heat exchanger, you can avoid chilling the premises with supply air on a start up under cold weather conditions.
Zero point calibration
The pressure sensor of the AHU is automatically calibrated. The
calibration process takes about 70 seconds after the AHU has
stopped (a notification is shown if the AHU has not stopped).
The zero point calibration text is displayed in the hand-held terminal. The fans cannot start while calibration is in progress.

sequences 1 and 2
Used for extra regulation functions controlled by a 0-10 V (10-0
V) signal with ordinary temperature regulation sequence.
Extra regulation
sequence 1/2
The function can be used for utilising existing heating or cooling
sources, such as from a chiller. The function can also be used for
an extra air heater or air cooler.
It can also be used for controlling dampers for recirculation, if
required. In these cases, an inverted 10-0 V output is used.
Recirculation control is used for the TBBD mixing section (GOLD
SD only) The 10-0 V inverted output should be in the On position.
The maximum output signal can be limited from 100% down to
0 %.
The output signal of the extra regulation sequence is controlled
from the TBIQ-3-2 IQlogic+ module accessory, see separate installation instructions.
When the SMART Link DX function is selected, the extra regulation sequence is automatically activated. The extra regulation
sequence cannot then be used for any other functionality. An
IQlogic+ module is not required (alarm for missing module is
blocked).
The extra regulation sequence makes it possible to control two
air heaters at the same time in the following combinations:
water - electricity, water - water, electricity - electricity (Season
heat, see also Section 4.11.7). The air heater for hot water is
available without or without frost guard function.
When the output of the first air heater is not sufficient, the
second is automatically brought into the sequence.
A start-up sequence, frost guard function, pump control, postcooling for electric air heater and other functionality are available.
For the start-up sequence, frost guard function, periodic operation and post-cooling, the same settings are used as for regular
reheating.

4.11.11 Automatic functions
Frost guard function, air heater for water
The frost guard function is always active if the connected air
heater for hot water has been supplied by Swegon.
The function activates a heating device that keeps the temperature in the coil at 13 °C while the air handling unit is operating and 25 °C in the coil when the unit is stopped. An alarm is
initiated and stops the AHU if the temperature sensor senses a
temperature below 7 °C.
Capacity reduction of the electric air heater
Only in combination with Swegon's electric air heater.
A min. permissible air velocity of 2.0 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 2.0 m/s across the heat
exchanger, the heating output of the air heater will be automatically reduced.

4.13.5 Defrost (GOLD RX)
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 it from becoming clogged due
to condensate that has frozen inside the exchanger.
Defrost
The function requires a separate pressure sensor (preset for heat
exchanger defrosting) wired to the control unit inputs for external BUS communication and connected to the AHU pressure
measurement tappings. 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.
Calibration is put into effect by setting Calibration to the On
position.
When the defrosting 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
implemented in which the rotor speed is gradually ramped down
(ramp time max. 4 minutes). The lowest permissible speed of the
rotor is 0.5 rpm. During the defrosting process, the warm extract
air thaws any possible ice that has formed on surfaces.
Extract air
If defrosting reduces the speed to the min. speed 0.5 rpm for
more than 2.5 h an alarm is generated.
Note that the heat exchanger performs less efficiently while
defrosting is in progress and that the supply air temperature will
also drop downstream of the heat exchanger.

4.13.7 Automatic functions
GOLD RX (rotary heat exchanger)
Purging function
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 AHU 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
surfaces clean of impurities.
Calculation of the efficiency
The efficiency is calculated and displayed (0 – 100%).
GOLD CX/SD (coil heat exchanger)
Pump control, 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.
Anti-frost protection
In cold weather, and if the extract air is humid, there is risk of
frosting in the coil heat exchanger. The GOLD CX/SD is equipped
with anti-frosting protection.
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
regulated to prevent the circulated liquid from dropping below
this temperature.
GOLD PX (plate heat exchanger)
Calculation of recovered energy
Recovered sensible energy is calculated and the values are displayed (instantaneous and accumulated).
In cold weather, and when the extract air is humid, there is risk
of frosting in the plate heat exchanger. The GOLD PX is therefore
equipped with anti-frost protection.
Cooling recovery
Cooling recovery is an automatic function that helps the air handling unit on a cooling load and high outdoor air temperature
to utilize the relative "cooling energy" that can be indoors. The
heat exchanger rotates at max. speed and in this way recovers
the relative cooling energy or chilliness in the extract air.
Anti-frost protection, standard
The pressure drop across the heat exchanger and the outdoor air
temperature are measured.
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 stops when the cooling load
ceases to exist or when the outdoor temperature is the same as
that of the extract air.
Overtime heat exchanger operation
If the AHU stops, the heat exchanger automatically continues to
recover heat for about 1 minute.
It takes a little time for the fans to stop rotating after a stop has
been ordered and this prevents the supply air from chilling the
premises.
52
www.swegon.com
With consideration given to the pressure drop across the heat
exchanger and the outdoor air temperature, the control system
regulates dampers for bypass and heat exchanger (interlinked) in
order to prevent the formation of frost.
RECOfrost anti-frost protection
The pressure drop across the heat exchanger, extract air temperature, moisture content in the extract air and outdoor air
temperature are measured.
With consideration given to the pressure drop across the heat
exchanger, the extract air temperature, the moisture content
in the extract air and the outdoor air temperature, the control
system individually regulates dampers for bypass and the heat
exchanger for section-by-section defrosting without the formation of frost.

Steam humidification (0 - 10V)
The function is appropriate for operation together with a steam
humidifier (not supplied by Swegon) and is a variable control system via 0-10 V control signal, as well as a contact function which
interlocks the humidifier if the air handling unit stops, if Summer
night cool is used or if the humidity in the supply air exceeds the
set point by more than 10%.
The function requires accessories IQlogic Plus module TBIQ-3-1
and 1 humidity sensor TBLZ-4-31-1 (for supply air regulation) or
2 humidity sensors (for extract air regulation or room control)
TBLZ-4-31-1 and TBLZ-4-31-2 or TBLZ-4-31-1 and TBLZ-4-31-6,
see separate installation instructions. Install the humidity sensors
in the extract air duct or in the premises as well as in the supply
air duct, see the drawing.
The function keeps the humidity level constant in the extract air
duct or premises by regulating the humidity in the supply air.

4.16.3 Dehumidifying
The function is intended for dehumidifying the supply air in order
to prevent condensation in the supply air duct or in connected air
conditioning products.
Dehumidifying
The dehumidification regulation function controls the humidity
in the supply air duct or the extract air duct by means of an air
cooler and an air heater for reheating.
The function requires that an air cooler be mounted upstream of
the air heater in the supply air duct. See the example to the right.
If control of the humidity in the supply air duct is required, install
a TBLZ-4-31-1 humidity sensor in the supply air duct. If control
of the humidity in the extract air duct is required, install a TBLZ4-31-2 humidity sensor in the extract air duct and a TBLZ-4-31-1
humidity sensor in the supply air duct. Connect the sensor to the
AHU. See separate installation instructions.
Example: Dehumidification regulation
TBLZ-4-31-2 Humidity sensor
Temperature
sensor, supply air
Cooling energy is emitted to condense the moisture in the supply
airflow, 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.

4.17 ReCO2
The ReCO2 function is designed for ensuring the correct
air quality or air temperature, by means of recirculating
extract air and minimizing the inflow of outdoor air.
ReCO2
The function can be used in ventilation systems in which recirculated air intermixture is acceptable.
The function presupposes that the outdoor air damper and the
damper in the air recirculation section are equipped with modulating damper actuators.
Lower outdoor air and exhaust air flows as well as lower extract
air fan speed enable the unit to consume less power. A separate
air quality sensor continuously measures the air quality of the
ventilation system.
The pressure drop across the rotor must then be calibrated to
establish a reference pressure drop for the function. Calibration
is put into effect by setting Calibration to the On position.

It is possible in the hand-held micro terminal to select whether
the power roof ventilator should be controlled in parallel with
the GOLD unit, and whether it should follow the low-speed/
high-speed operating modes of the air handling unit.
The balanced ventilation function can be used if the power
roof ventilators are used for variable flow. It is then possible to
select which power roof ventilator(s) is/are to be included in the
function.
In the case of balanced extract air, all the airflows of the activated power roof ventilators are added together. The extract
airflow in the GOLD unit is decreased by the corresponding
volume. In this way the supply airflow will be the same as the
total extract airflow and balanced ventilation will be achieved
inside the building.
In the case of balanced supply air, all the airflows of the activated power roof ventilators are added together. The supply
airflow in the GOLD unit is increased by the corresponding
volume. In this way the supply airflow will be the same as the
total extract airflow and balanced ventilation will be achieved
inside the building.
The function presupposes that pressure sensors for flow measurement and possible pressure regulation are connected to
MIRO Control.
All the time channels available in MIRU Control can be set separately for each connected power roof ventilator via the GOLD
unit hand-held micro terminal. For a description of the function,
see the separate Guide to the MIRU Control Functions.
Depending on the function selected in MIRU Control, it is possible to set the desired set point for pressure or flow, low speed
and high speed, in the GOLD unit hand-held micro terminal.
For a description of the function, see the separate Guide to the
MIRU Control Functions.

4.25 Manual test
NB! Manual test running can cause indoor comfort problems. There is also risk of overloading the system. The
responsibility for discomfort and overload rests totally on
the person who activates the function.
Manual test
When you enter manual test, select safe mode or operating
mode. Safe mode involves stopping the AHU and being able to
run each installed function separately or together. Operating
mode involves permitting the AHU to continue to operate in the
normal operating mode and installed functions can be influenced manually.
Manual test operation can take place for testing the inputs and
outputs, fans and heat exchanger, etc.
Used for installation or troubleshooting to test that wired connections and functions operate correctly.
Certain alarms, functions and normal control modes will be
blocked while manual testing is in progress.
Each image indicates which functions can be test run.
