) Function possibilities with SPDT contact, connected to the
terminals 3 and 4 are the following:
Door alarm: If SPST is cut out, alarm signalling starts and the fan is
stopped, cf. A04 or F02.
Defrost: If SPST is cut in, defrost starts. (However, if d03 is not OFF,
defrost will during contact break down start with the programmed time
intervalles).
Bus: With installed communication card, the position of the SPST
contacts will be registered in the BUS system.
