Function
Hrec efficiency
Calculation for heat recovery efficiency.
Requirement: Heat recovery (e.g. rotary heat exchanger) must be en-
abled and an outside air temperature as well as a return air sensor
must be available.
No
No calculation of heat recovery efficiency.
ExhaustAir
To calculate using exhaust air: One analog input for the exhaust sen-
sor if not already enabled for Hrec frost.
SupplyAir
To calculate with a supply air sensor: On analog input for the supple-
mental supply air sensor.
Htg frost protect
No
No frost protection.
sensor
Frost protection using a sensor. An analog input for controlled frost
protection using a setpoint.
Sensor2Spv
Frost protection using a sensor and 2 setpoints. An analog input for
controlled frost protection using two setpoints fir StandBy and opera-
tion.
Detector
Frost protection using a detector. Digital input for frost detector.
Snsr+Dtctr
Frost protection using a sensor and detector. An analog input for con-
trolled frost protection and a digital input for the frost detector.
2Spv+Dtctr
Frost protection using a sensor, 2 setpoints and detector. An analog
input for controlled frost protection using two setpoints for StandBy
and operation and a digital input for the frost detector.
Heating pump
No
No heating register pump.
Yes
Heating register pump without pump kick. Digital output for the pump.
Yes+Kick
Heating register pump with pump kick. A digital output for pump and
activation of pump kick.
Pump kick: Pump is switched on for a short period after idling for a
longer period. This prevents lock up.
Heating pump
alarm
No
Pump without alarm or feedback.
Alarm
Pump with alarm. Digital input for pump alarm. Logical 1 = alarm, im-
mediately shuts down the pump.
Fdbk
Pump with feedback. Digital input for feedback (logical 1 = Pump run-
ning).
Both
Pump with alarm and feedback. Two digital inputs for pump alarm and
feedback.
Combi Coil
A register used for heating and cooling with 2 or 4 pipe connections.
Requirement: Heating and cooling with water are enabled.
No
No combi coil.
1Output
Combi coil with a common output. The previously enabled output for
cooling valve is disabled.
2Outputs
Combi coil with two separate outputs.
Note: The CombiCoil uses only one (heating) physical output for pump
control. The cooling pump should always be enabled if it runs for re-
frigeration demand. Use only heating pump alarm/feedback.
El htg alarm
No
No alarm.
Yes
A digital input for the alarm is enabled (logical 1 = Alarm).
Hum control mode
Select control algorithm for temperature control.
No
No humidity control.
Room
Room humidity control only.
Supply
Supply air humidity control only.
RmSplyCasc
Room supply cascade control.
Requirement: Room and supply air humidity sensor is enabled.
