Pump by Time
When Ultra Wizard = 2 Pump/Differential
When a relay is assigned to Pump by Time the pump will come on
(energise) at its normal “ON” level setpoint, and de-energise at its OFF
level setpoint or after a predetermined time period, whichever occurs first.
P210, 220, 230, 240, 250 = 5 (Pump by Time)
When a relay is being used for a pump by time function, the second
parameter determines the pump duty that will be used to determine the
operating cycle.
P211, P221, P231, P241, P251 - 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,
243, 253 & P214, 224, 234, 244, 254).
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, 243, 253 &
P214, 224, 234, 244, 254).
All pumps are used to assist each other
(run at the same time). Each pump has
its own setpoints, (P213, 223, 233, 243,
253 & P214, 224, 234, 244, 254) but
each time all pumps have stopped, the
setpoints are sequentially rotated
between the pumps to ensure equal
pump use.
