) The compressor relay closes when the room temperature exceeds
the setting value and differential.
2
) Alarm is released and sensor failure is indicated, if the room
temperature reaches 5°C or more outside the setting range
–60° to +50°C.
3)
The frequency is measured after approx. three days and
nights operation after start of the plant (72 cyclings)
otherwise:
ON-time = c03 × 20: 100 minutes
OFF-time interval 20 minus ON-time per minute

) 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.
