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 F03.
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.
Main Switch: Start/stop control

- Keep both buttons depressed at the same time as you reconnect the supply voltage
