Pumps
When Ultra Wizard = 2 Pump
P210, 220, 230 = 2 (Pump)
When a relay is being used for a pump function, the second parameter
determines the pump duty that will be used to determine the operating
cycle.
P211, 221, 231 – Relay Function
This parameter defines which pump duty the relay should respond to as
follows:
Relay is always de-energised
All pumps are used to assist each other (run at the
same time) and each pump has its own setpoints.
(P213, 223, 233 & P214, 224, 234).
If a pump fails to meet the demand (due to
malfunction, intake blockage etc.), then it is
stopped, and another pump shall take over. Each
pump has its own setpoints. (P213, 223, 233 & P214,
224, 234).
3 = Alternate duty assist
All pumps are used to assist each other (run at the
same time) and each pump has its own setpoints,
(P213, 223, 233 & P214, 224, 234). but each time all
pumps have stopped, then the setpoints are
sequentially rotated between the pumps to ensure
equal pump use.
4 = Alternate duty backup
If a pump fails to meet the demand (due to
malfunction, intake blockage etc.), then it is
stopped, and another pump shall take over. Each
pump has its own setpoints, (P213, 223, 233 & P214,
224, 234). but each time all pumps have stopped,
then the setpoints are sequentially rotated between
the pumps to ensure equal pump use.
