Reading of pump status
0: Pumps have stopped
1: Cold pump 1 is in use
2: Cold pump 2 is in use
3: Both pumps are in use
Current status for flow switch input
Actual status for input "Pump 1"
Actual status for input "Pump 2"
Main switch:
Choice of pump operation
0: Both pumps are stopped
1: Cold pump 1 is in constant use
2: Cold pump 2 is in constant use
3: Both pumps are in constant use
4: Off set of operational time between the two pumps. Start before stop
5: Off set of operational time between the two pumps. Stop before start
The operational times of the pumps before pump switch is carried out (pump's opera-
tional time before changeover to the other pump)
Overlap time during pump changeover where both pumps are in use or break time
when switching between two pumps (only relevant if "Cold Pump ctrl" is set to 4 or 5)
Delay on pump alarm before alarm is activated and automatic pump changeover car
ried out (only if "Cold Pump ctrl" is set to 4 or 5)
