If uninterrupted fan operation is needed and cold draft air is avoided for example by some internal
bypass etc., the defrost signal (for MAH2/PAH2 generation models: contacts C5 (ON1) and C6
(ON2); for PAH3 generation model: OP1 and OP2) can be used with an additional field supplied
relay.
Blower protection input (for MAH2/PAH2 generation models only)
If a switch opens, an alarm “P01” appears on a remote controller display, and operation stops.

must be closed, because otherwise the AHU Kit cannot work.
