The hot ware registers can be operated with pump (pump kick, alarm, feedback) or
without pump. Frost detection and controlled frost protection is integrated. The ad-
ditional heating register can be operated as a separate register with its own set-
point. The heating register is forced off if:
– Night unoccupied (temperaturstart) cool
– Summer night cooling
– Combicoil at summer (only heating, not heating2)
A maximum of one of the two additional registers Heating 2 or El heating 2 can be
integrated into the temperature control sequence.
