Remarks about P13 to P15:
Whit P13 it is possible to enter a limit for switching on the first compressor. As soon as the
pressure is higher then P13 the first compressor will switch on without delay. The minimal off
time (P20) will still be valid.
If the value from P15 is lower then the value of P14 then the value of P14 will be used. If
another step has to switch on, the value of P15 will be used.
Remarks about P500 to P521:
When one or more inputs are closed the input with the lowest setpoint will be active as setpoint
for the compressors!
During the readout of the setpoint a flashing ‘c’ will indicate that an input is active. In this mode
the set point CANNOT be changed.
