Important Information
The pumps are started and stopped at the “ON” and “OFF” setpoints. To
pump down (reduce level) then set “ON” higher than “OFF”. To pump up
(increase level) then set “ON” lower than “OFF”.
The third parameter for each relay determines the pump group. You can
have two groups of pumps, and all similar duties within a group will operate
together.
P212, P222, P232 - Relay Pump Group
By default, all pump groups are set to 1, but if you want to have another
group, then set this parameter to 2, for each pump relay that should operate
together as part of a second group.
The fourth parameter and the fifth parameter for each relay set the pump
“ON” and “OFF” points, which are entered in Measurement units P104.
For pump down the “ON” is set higher than “OFF”. For pump up then
“ON” is set lower than “OFF”. See the appropriate pump duty, function
table (P212, 222, 232) for further information.
P213, P223, P233 - Relay Setpoint 1
This parameter determines the “ON” point of the pump.
P214, P224, P234 - Relay Setpoint 2
This parameter determines the “OFF” point for the pump.
The sixth parameter will determine the service ratio that will be used to
switch the pump, when pump duty selected is a Service Ratio duty.
P211, 221, 231 = 6, 7 or 9 (Service ratio)
P215, P225, P235 - Relay Setpoint 3
This parameter determines the Service Ratio in values of %. See the
appropriate pump duty function, table (P211, 221, 231), for further
information.
