Siemens Standard application AHU CE1P3977en_02
Building Technologies Configuration 01.02.2010
Parameter Range 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.
