P213, P223, P233 - Relay Setpoint 1
This parameter determines the “ON” point for the general control relay Relay
Setpoints are entered in values of Measurement Units (P104)
P214, P224, P234 - Relay Setpoint 2
This parameter determines the “OFF” point for the general control relay Relay
Setpoints are entered in values of Measurement Units (P104)
P219, P229, P239 - Relay Max.Rate
This parameter will allow a General Control Relay to be switched at a pre-
determined Rate of change of Level, irrespective of the “ON” level setpoint
P213, 223, 233. Once a General Control relay has been switched “ON” by
the pre-determined Rate of Change, it will remain energised until the level
reaches the “OFF” level setpoint P214, 224, 234.
Max. Rate is entered in Measurement Units (P104) per minute and can be
entered as either positive (increasing level) or negative (decreasing level)
values.
Pumps
When Ultra Wizard = 2 Pump or 3 Flow
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, P221, P231 - Relay Function,
This parameter defines which pump duty the relay should respond to as
follows.

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. (P213, 223, 233 &
P214, 224, 234).
