Both electric registers can be deployed with up to 3 stages (binary). An alarm is
possible for each register. Register output is limited by fan out, which prevent the
register from overheating. The additional electric heating register can be operated
as a separate register with its own setpoint.
The electrical heating register is forced off if:
– Night unoccupied (temperaturstart) cool
– Summer night cooling
A maximum of one of the two additional registers Heating 2 or El heating 2 can be
integrated into the temperature control sequence.
The stages are controlled as follows for electric heating registers:
DO1 DO2
Off 0 0
Stage1 1 0
Stage2 0 1
Stage3 1 1
