3. Filter Calibration
All the fi lters should be calibrated when the fans are started up for the fi rst time and when the duct system, air terminals and commissioning plates, if required, have been installed and commissioned.
After that every time fi lters are replaced. Calibration should then be activated for the fi lter or fi lters that are new. Relevant fi lters are the Supply air prefi lter, Extract air pre-fi lter, Supply air AHU fi lter, Extract air AHU fi lter, SA and EA AHU fi lter and Supply air end fi lter.
When fi lter calibration is activated, the air handling unit runs at the preset max. speed (depending on the functionality selected) for about 70 seconds.
After the fi lters have been calibrated, a pressure rise of up to 100
Pa is permissible (as the fi lters arrest impurities) after which an alarm indicating fouled fi lter is initiated. The alarm limit can be changed under Installation, Functions, Filters.
The fi lter function must be activated (see Section 4.5) in order to make it possible to enable fi lter calibration and alarm functions of the end fi lter and pre-fi lter in GOLD SD supply air and extract air handling units.

4.1.2 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, m 3 /s, m 3 /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.
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 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.

4.1.8 Outdoor air compensation
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.

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.

4.2 Temperature
N.B.!
If the entry of new temperature settings involve large changes, you should fi rst stop the AHU before you enter the new settings.
Specifi c temperatures, such as set points, should be specifi ed in °C or °F, whereas displacements, deviations and differentials should be specifi ed in K (Kelvin).
If only GOLD SD supply air handling units are installed, they require an external room sensor for ERS, ORE and extract air regulation.

All the relevant values can be read here. Used for performance checks.
4.2.2 Settings
ERS Regulation 1
ERS regulation refers to 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 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.

Supply air regulation
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.

When the extract air temperature is 22 °C (X4), the supply air temperature set point is regulated from 14 °C (Y3) down to 12
°C (Y4).
If the extract air temperature is over 22 °C (X4), the supply air temperature set point will constantly be 12 °C (Y4).
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
COM1-3).

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.

4.2.5 Set point displacement
Used for changing the supply air and extract air temperature set points by means of an external 0-10 VDC signal. For example, the temperature can be increased or decreased at certain times of the day by means of an external timer or potentiometer.
The accessory, IQlogic + module TBIQ-3-2, is required.
The set point can be influenced by ±5 °C.
If the AHU is operating in the supply air regulation or ORS regulation mode, the supply air temperature set point is displaced and the AHU is operating in the extract air regulation or ORE regulation mode, the extract air temperature set point is displaced.
When the AHU 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 AHU is operating in the ERS regulation 2 mode, the supply air set point will be displaced.
When the function is activated, the set point is displaced as plotted in the diagram to the right.
Set point displacement will not affect any possible extra temperature zone (Xzone) which regulates according to its ordinary set point if set point displacement is in operation.

On the basis of the measured values for relative humidity and temperature, the current dew point (the temperature at which the moisture in the air condenses) is calculated. When the dew point exceeds the supply air temperature, the supply air set point is raised to counteract condensation precipitation.
The air flow can be increased to compensate for any losses in cooling capacity with an increasing supply air temperature.

The sensor can be selected to control only intermittent night heat and/or summer night cooling (the AHU is then controlled during the daytime in response to signals from the internal sensor inside the AHU).
Locate the temperature sensors at suitable places to obtain representative readings.
The air handling unit is controlled in response to a computed mean value of the temperature sensors' readings, alternatively in response to signals from the temperature sensor that measures the lowest or highest value.
As an alternative, a temperature reading can be transmitted to the air handling via communication from e.g. a main system.

Cooling Boost (forced cooling) means that the supply air and extract air airflows are increased to convey more cool air to the premises.
The fans are permitted to operate in the range between current flow modes or pressure (low speed, high speed) and the preset max speed. See Section 4.1.2.
The function can be selected in five variants as follows:
Comfort
The cooling outputs are activated if there is a cooling load.
A regulated ramp function switches in and gradually increases the airflow when there is a cooling load, and the supply air 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.
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.
• 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.
• 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
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 fi ve 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.
The relevant region and city can be selected, summer time/winter time changover will then be managed automatically.
Time source can be set to manual or via SNTP (requires connection to network) and BACnet. The time format and date format can be set.
4.3.2 Schedule settings
The relevant operating mode can be read under Schedule settings. Here you can also set a preselected operating mode, in which the air handling unit always operates during non-programmed time, under Day schedule and Exceptions schedule.
This setting (start and stop date not activated) is used most often and covers the majority of needs.
When the start and stop date is activated, this means that during the preset period (date) preset time applies during the day schedule and the exceptions schedule, and at all other times the
AHU runs in the preselected operating mode.

4.8 Alarm settings
4.8.1 Fire alarms
Internal fi re alarm
The air handling unit’s internal temperature sensors serve as fi re 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.
If an external Extract air/Room temperature sensor is connected and activated, this works parallel with the extract air temperature sensor of the AHU.
External fi re alarm 1 and 2
External fi re alarm 1 (Terminals 6-7) and external fi re alarm 2
(Terminals 8-9) are used for external fi re-control equipment.
Alarm reset
The resetting of internal fi re alarms as well as the external fi re 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 fi re alarms as well as external fi re alarms 1 and 2.
Fan operation at fi re 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 fi re 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 fi re 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 fi re 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 fi re alarms can be set. If automatic is selected, this means that the fi rst input to be activated is given priority.
Fire bypass in fl ow diagram
The fi re bypass is shown on the hand-held terminal’s fl ow diagram when the function is activated. Fan operation for extract air must be active for at least one of the fi re alarms. Dampers switch to fi re bypass if any of the fi re alarms are active and the extract air fan is operational.

Set the type of air handling unit here. The type of air handling unit is normally preset for the unit supplied; except the GOLD SD extract air unit which must be set here.
N.B.!
Do not change the air handling unit setting to a type that differs from the one supplied. If you do so, the air handling unit will not operate satisfactorily.
The air handling unit can be given a specifi c name (e.g. the unit's serial number). Naming in the hand-held terminal can only be done with digits, however on the web page the naming can also be done with alphabetical characters. The given name is then shown in all the images in the hand-held terminal and web page.
The type of AHU, size of the supply air and extract air fan respectively can be viewed.
GOLD RX/PX/CX
The AHU’s fan position 1 (left-hand fan seen from the inspection side, see illustrations) can be read and preset.
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 fi lter class in the supply and extract air. If the fi lter classes for the supply and extract air are not equal, change the positions of the fi lters. RX Top 004-012 and 025/030 has supply and extract air fi lters 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 fl ow chart can be read and should be set according to the AHU's actual confi guration.

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.

4.11.3 Extra regulation sequences 1 and 2
Used for extra regulation functions controlled by a 0-10 V (10-0
V) signal with ordinary temperature regulation sequence.
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.

4.11.9 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.
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.
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%).
Calculation of recovered energy
Recovered sensible energy is calculated and the values are displayed (instantaneous and accumulated).
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.
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.
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)
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.
Anti-frost protection, standard
The pressure drop across the heat exchanger and the outdoor air temperature are measured.
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.

4.16.2 Humidifying
Evaporative humidification (On/Off)
This function is suitable together with an evaporative humidifier
(not Swegon).
Function requires accessories IQlogic + module TBIQ-3-1 and 1 humidity sensor TBLZ-4-31-2 or TBLZ-4-31-6, see separate installation instructions. Install the humidity sensor in the extract air duct or in the premises, see the illustration.
The humidity in the extract air duct/premises is regulated between adjustable start and stop limits.
A weekly timer with four time channels makes it possible to switch between two configurable start and stop limits.
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.
In order to prevent the humidity in the supply air from being too high, it is restricted to a maximum limit.
Alternatively the humidity in the supply air duct can be kept constant by selecting a regulating humidity sensor in the supply air.
The set point cannot be set higher than the max limit. If the dehumidification function is activated, the max limit cannot be set higher than the set point for dehumidification.
A weekly timer with four time channels makes it possible to switch between two configurable start and stop limits.

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.
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-2-31-1 humidity sensor in the supply air duct. If control of the humidity in the extract air duct is required, install a TBLZ-
2-31-2 humidity sensor in the extract air duct and a TBLZ-2-31-1 humidity sensor in the supply air duct. Connect the sensor to the
AHU. See separate installation instructions.
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 ReCO
The ReCO

function is designed for ensuring the correct air quality or air temperature, by means of recirculating extract air and minimizing the infl ow of outdoor air.
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 fl ows 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.
For more information, see the ReCO

4.19 MIRU
4.19.1 Roof ventilator MIRUVENT, version MIRU-1 and -2
Up to ten power roof ventilators with MIRU Control equipment can be connected to one GOLD air handling unit by means of bus communication.
If one or several power roof ventilator(s) is/are stopped via the control panel on the corresponding MIRU Control, the power roof ventilator(s) cannot be started via the GOLD unit hand-held terminal.
The settings in the hand-held micro terminal of the GOLD unit override the settings in the MIRU Control’s control panel.
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 fl ow. 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 airfl ows of the activated power roof ventilators are added together. The extract airfl ow in the GOLD unit is decreased by the corresponding volume. In this way the supply airfl ow will be the same as the total extract airfl ow and balanced ventilation will be achieved inside the building.
In the case of balanced supply air, all the airfl ows of the activated power roof ventilators are added together. The supply airfl ow in the GOLD unit is increased by the corresponding volume. In this way the supply airfl ow will be the same as the total extract airfl ow and balanced ventilation will be achieved inside the building.
The function presupposes that pressure sensors for fl ow 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 fl ow, 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.
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 infl uenced 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.
