FUNCTIONAL DESCRIPTION SMART CONTROL

Control:Air Handling unit operation states can be controlled with Smart User Panel, Smart cooker hood, Smart Access web application, external switches, week scheduler, or automatic with CO2 sensor*. Operation states can be controlled also from automation system through Modbus RTU or with voltage or DI control. Basic operation states are Away / Home / Boost but it's also possible to control unit to Travelling or Stopped state.

Fan Control:Fans are controlled either with constant control or with constant duct pressure* based on levels adjusted in commissioning. Fan control levels are adjusted for each basic operation mode. If fans are controlled steplessly between adjusted states, fan control levels are scaled to maintain balance in entire adjusted range.

Temperature control:Supply temperature is controlled by controlling post heater in heating period. During summer period supply temperature is controlled by controlling heat exchanger efficiency and by controlling cooling coil power*. Supply temperature setpoint can be changed from User Panel, by week scheduler, by operation modes, by automatic summer night cooling function or by building automation. Alternatively supply temperature setpoint can be controlled based on room temperature, in that case room temperature setpoint and supply temperature min/max values are defined.

Cooling:Automatic summer night cooling function detects building cooling need. Function decreases automatically supply air temperature settings in order to achieve best cooling effect. Function controls heat exchanger efficiency with bypassing the exchanger and cooling power* to reach the setpoint. Function observes also extract temperature and recovers building cool air if needed by controlling heat exchanger. Summer night cooling function effective can be changed from Smart user panel, from Smart Access or trough modbus interface. Cooling BoostAutomatic cooling boost function, boost ventilation steplessly if high cooling need is detected and supply air temperature is relatively low to achieve cooling effect.

Cooker hood balancing functionCooker hood function balances and boosts if needed the air flows. Function is activated automatically when Smart cooker hood damper is opened. It can be also activated by damper status signal connected to AHU DI. Air Flow balancing is achieved by increasing the supply airflow or by decreasing the extract airflow (roof fan). Balancing and boost levels can be adjusted in commissioning mode.

Fireplace functionIntelligent fireplace function aids firing the fireplace by creating temporary overpressure into building. After overpressurizing period, the function aims to compensate internal pressure by bringing replacement air for fireplace. Note! Always bring enough replacement air to fireplace with external duct. Auto Humidity Control Ventilation unit is equipped by default with humidity automation which boost ventilation steplessly based on humidity

Boost level can be changed if needed.

Auto Home/Away/Boost function*Function control ventilation level steplessly between Away-Home-Boost states based on CO2 Level. Function sets unit also to Away CO2 level is below Away limit which can i.e. decrease supply temperature setpoint in order to save energy. Function must be adjusted by setting Limit for Away state and for Home state.

Auto Air Quality control*Function increases ventilation level steplessly according to the VOC level in the building. Function works automatically and boosting level can be changed if needed.

Fans:Fans are equipped with internal automatic overheating protection.

CONTROL SYSTEM PROTECTION FUCNTIONS

Filters:Filter change need is indicated with service reminder. Service need is indicated in Smart User Panel, in Smart Access, in Smart Cooker hood, in DO state indication or in modbus data. Service reminder is disabled by default and it needs to be activated. Service time is changeable (default 6months).

Heater / (Cooling) coils:Water based coils are equipped with freeze protection sensor. If outside temperature is below 0C and water temperature drops below alarm limit freezing danger alarm is activated and actuator is controlled fully open. If unit is equipped with internal electrical post heater, it is controlled to full power. If despite protective actions water temperature drops below Stop limit, the unit is controlled to Stopped state, and duct dampers are controlled to close position. Note. Always use duct damper for fresh air duct is unit is equipped with water-based heating / cooling coil.Note. If water based cooling coil is used, activate freezing protection sensor to system.

Heat Exchanger:Unit includes automatic defrost function based on temperatures. Defrost function guarantees heat exchanger continuous and reliable operation. Defrost is executed by heating fresh air and by limiting fan speeds. Because heat exchanger is never bypassed in cold climate, supply air temperate will stay in safe level even in extreme cold conditions.

Supply temperatur:If supply temperature drops too low, because unit malfunction, supply temperature cold protection will stop the unit. Unit starts automatically when temperature has risen to safe level.

Electrical heaters:Electrical heaters have constant diagnostic. If heater circuit is broken it gives heater alarm. If circuit is broken constantly because automatic overheat protection or if it is not reset, heating is controlled off and supply for heaters are controlled off by means of internal relay.

ALARMSMalfunction is indicated with alarm in Smart User Panel, Smart Access, DO alarm output or modbus data. Critical malfunction is also indicated in Smart cooker hood. When malfunction cause is removed alarms is reset and info of alarm will stay until it is reset from user interface.

If fans are controlled stepless between adjusted states, fan control levels are scaled to maintain balance in the entire adjusted range.

Temperature control:Supply air temperature is controlled by controlling heat exchanger bypass plate steplessly and if needed controlling the heating or cooling* coils. Supply air temperature control behavior can be selected with the Control method to ECO or Comfort. In the ECO mode heat exchanger bypass plate is always kept closed except when automatic summer night cooling function is active. During the summer night cooling function bypass plate is controlled to allow cold outside air to flow into the building. Note that in ECO mode high extract air temperature affects to supply air temperature. In the Comfort mode, the supply air temperature is controlled to be constant by controlling the heat exchanger bypass plate. Post heating and cooling devices are working similarly no matter which mode is selected. Note that the default setting for the control method is ECO.

Supply temperature setpoint can be changed from User Panel, by week scheduler, by operation modes, by automatic summer night cooling function or by building automation. Alternatively, the supply temperature setpoint can be controlled based on the room temperature, in that case, the room temperature setpoint and supply temperature min/max values are defined. Note that the air handling unit can not generate colder supply temperature as the outside temperature is without a cooling coil.

Cooling:Automatic summer night cooling function detects building cooling needs. Function decreases automatically supply air temperature settings to achieve the best cooling effect. Function controls heat exchanger efficiency by bypassing the exchanger and controlling the cooling power* to reach the setpoint. Function observes also extract temperature and recovers building cool air if needed by controlling heat exchanger.

If the outside temperature is below 0°C and water temperature drops below the alarm limit freezing danger alarm is activated and the valve is controlled fully open. If the unit is equipped with an internal electrical post heater, it is controlled to full power. If despite protective actions water temperature drops below the Stop limit, the unit is controlled to the Stopped state, and duct dampers are controlled to close position. Note. Always use duct damper for fresh air duct is unit is equipped with water-based heating/cooling coil.Note. If a water-based cooling coil is used, activate freezing protection sensor to system.

Heat Exchanger:The unit includes learning demand defrost function which is based on extract air humidity, and temperatures which guarantee continuous optimal efficiency for the heat exchanger. Defrost is implemented by heating the outside air before the heat exchanger, this allows that heat exchanger is not needed to bypass which causes heat exchanger efficiency drop. The defrost function controls the exhaust air temperature in which setpoint is controlled to optimal based on extract air humidity and the learning function. Because defrost function is stepless and continuous, the unit air flows are not needed to limit than only in very cold climates when the heat exchanger and electrical heaters total power is not enough to heat the required airflows. In this instance, the unit total airflow is decreased only the minimum amount and still, the airflows are kept in balance.

Supply temperature:If supply temperature drops too low, because unit malfunction, supply temperature cold protection will stop the unit. The unit starts automatically when the temperature has risen to a safe level.

Electrical heaters:Electrical heaters have constant diagnostic. If the heater circuit is broken it gives heater alarm. If the circuit is broken constantly because automatic overheat protection or if it is not reset, heating is controlled off and supply for heaters is controlled off using an internal relay.

ALARMSMalfunction is indicated with alarm in Smart User Panel, Smart Access, DO alarm output or Modbus data. Critical malfunction is also indicated in the Smart cooker hood. When malfunction cause is removed alarms are reset and info of alarm will stay until it is reset from the user interface.

Control:Air Handling unit operation states can be controlled with Smart User Panel, Smart cooker hood, Smart Access web application, external switches, week scheduler, or automatic with CO2 sensor*. Operation states can be controlled also from the automation system through Modbus RTU or with voltage or DI control. Basic operation states are Away / Home / Boost but it's also possible to control unit to Travelling or Stopped state.

Fan Control:Fans are controlled either with constant control or with constant duct pressure* based on levels adjusted in commissioning. Fan control levels are adjusted for each basic operation mode. If fans are controlled stepless between adjusted states, fan control levels are scaled to maintain balance in the entire adjusted range.

Temperature control:Supply air temperature is controlled by controlling heat exchanger bypass plate steplessly and if needed controlling the heating or cooling* coils. Supply air temperature control behavior can be selected with the Control method to ECO or Comfort. In the ECO mode heat exchanger bypass plate is always kept closed except when automatic summer night cooling function is active. During the summer night cooling function bypass plate is controlled to allow cold outside air to flow into the building. Note that in ECO mode high extract air temperature affects to supply air temperature. In the Comfort mode, the supply air temperature is controlled to be constant by controlling the heat exchanger bypass plate. Post heating and cooling devices are working similarly no matter which mode is selected. Note that the default setting for the control method is ECO.

Supply temperature setpoint can be changed from User Panel, by week scheduler, by operation modes, by automatic summer night cooling function or by building automation. Alternatively, the supply temperature setpoint can be controlled based on the room temperature, in that case, the room temperature setpoint and supply temperature min/max values are defined. Note that the air handling unit can not generate colder supply temperature as the outside temperature is without a cooling coil.

Cooling:Automatic summer night cooling function detects building cooling needs. Function decreases automatically supply air temperature settings to achieve the best cooling effect. Function controls heat exchanger efficiency by bypassing the exchanger and controlling the cooling power* to reach the setpoint. Function observes also extract temperature and recovers building cool air if needed by controlling heat exchanger. Summer night cooling function effective can be changed from Smart user panel, from Smart Access or trough Modbus interface.

Cooling BoostAutomatic cooling boost function, boost ventilation steplessly if high cooling need is detected and supply air temperature is relatively low to achieve the cooling effect.

Cooker hood balancing functionCooker hood function balances and boosts if needed the air flows. The function is activated automatically when the Smart cooker hood damper is opened. It can be also activated by a damper status signal connected to AHU DI. Air Flow balancing is achieved by increasing the supply airflow or by decreasing the extract airflow (roof fan). Balancing and boost levels can be adjusted in commissioning mode.

Fireplace functionIntelligent fireplace function aids in firing the fireplace by creating temporary overpressure into the building. After the overpressurizing period, the function aims to compensate internal pressure by bringing replacement air for the fireplace. Note! Always bring enough replacement air to the fireplace with an external duct.

Auto Humidity Control The ventilation unit is equipped by default with humidity automation which boosts ventilation steplessly based on humidity generated by

if needed.

Auto Home/Away/Boost function*Function control ventilation level steplessly between Away-Home-Boost states based on CO2 Level. The function sets the unit to Away mode when the CO2 level is below the Away limit. This can be used to decrease the supply temperature setpoint to save energy. The function must be adjusted by setting Limit for Away state and Limit for the Home state.

Auto Air Quality control*The function increases ventilation level steplessly according to the VOC level in the building. The function works automatically and boosting level can be changed if needed.
