OFFSET
The OFFSET time defines the target difference in running hours between one unit and another unit
with OFFSET:0000 h. This value is important for maintenance purposes. The difference in setting
among different units should be high enough as to avoid servicing of the units all at the same time. The
lower and upper limits are 0 and 9000 hours respectively. The default value is 0 hours.
For units with 2 circuits, the individual lead/lag setting is valid as to determine the priority of the circuits.
E.g. if following setting is made:
Unit 1 = 0 h
Unit 2 = 1000 h
Unit 3 = 2000 h
Unit 4 = 2000 h
Then unit 3 and 4 will be operated most. They will get priority in operation as to reach 2000 running
hours more than unit 1. Unit 1 will be the unit with the lowest running hours.
PUMP ON IF
Set if the pump must operate as long as the chiller is ON (UNIT ON), or during compressor on condition
only (COMPR ON).
P When UNIT ON is selected, the voltage free contact S9L will remain closed as long as the chiller
is ON.
The pump of individual unit will run if unit is on.
P When COMPR ON is selected, the voltage free contact S9L will remain closed as long as the
compressor is ON.
The pump of an individual unit will run only if the compressor is on of that unit.
P When COMPR ON is selected, the voltage free contact S9L will remain closed as long as the
compressor is ON.
The pump of an individual unit will run only if the compressor is on of that unit.
