Controller application setting parameters
Quick Guide
1) 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 x 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 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.
