Parameter Range Function
Both Pump with alarm and feedback. Two digital inputs for pump alarm and
feedback.
Cooling DX alarm No Direct expansion evaporator without alarm or feedback.
Alarm Direct expansion evaporator with alarm. Digital input for pump alarm.
Logical 1 = alarm, immediately shuts down the pump.
Fdbk Direct expansion evaporator with feedback. Digital input for feedback
is enabled (logical 1 = Pump running).
Both Direct expansion evaporator with alarm and feedback. Two digital in-
puts for alarm and feedback.
Heating 2 frost
protect
No No frost protection.
sensor Frost protection using a sensor. An analog input for controlled frost
protection using a setpoint.
Sensor+2Spv 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 2 pump No No pump.
Yes Pump without pump kick. Digital output for the pump.
Yes+Kick 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 2 pump
alm
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.
Heating 2 control Positioning of additional hot water register.
StandAlone Hat water register not integrated in sequence. An additional analog
input for one control sensor (if not already enabled for El Heating 2 or
Cooling 2).
InSequence e.g. integrated as re-heater in the sequence.
Note: A maximum of one of the two additional registers (Heating 2 or
El heating 2) can be integrated into the sequence.
El heating 2 alarm No No alarm.
Yes A digital input for the alarm is enabled (logical 1 = alarm).
El Heating 2 control Positioning of additional electric register.
StandAlone Electric register not integrated in sequence. An additional analog input
for one control sensor (if not already enabled for Heating 2 or Cooling
2).
InSequence e.g. integrated as re-heater in the sequence.
Note: A maximum of one of the two additional registers (Heating 2 or
El heating 2) can be integrated into the sequence.
