Pumps
When Ultra Wizard = 2 Pump or 3 Flow
P2n0 = 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.
P2n1 – Relay Function
This parameter defines which pump duty the relay should respond to as
follows:
PUMP DUTY
DESCRIPTION
0 = Off (Default)
Relay is always de-energised
1 = Fixed duty assist
All pumps are used to assist each other (run at the
same time) and each pump has its own setpoints.
(P2n3 & P2n4).
2 = Fixed 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. (P2n3 & P2n4).
3 = Alternate duty assist
All pumps are used to assist each other (run at the
same time). Each pump has its own setpoints, (P2n3
& P2n4) 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, (P2n3 & P2n4) but each
time all pumps have stopped, then the setpoints are
sequentially rotated between the pumps to ensure
equal pump use.
