) 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
4
) Function possibilities with SPST 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.
