P219, P229, P239 - Relay Max.Rate
This parameter will allow a pump to be switched at a pre-determined Rate
of change of Level, irrespective of the “ON” level setpoint P213, 223, 233.
Once a pump 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.
Control
P210, 220, 230 = 3 (Control)
When a relay is being set as a control relay, the second parameter that will
be displayed in the menu determines its function.
P211, P221, P231 - Relay Function,
This function allows the relay to be assigned to specific control functions
and mainly work in relation to time.

Description
0 = Off
(Default)
Relay is always de
-
energised
1 = Time
Relay will energise “ON” after the Cycle
time that is set in Relay Setpoint 2 (P214,
224, 234). And turns “OFF”, de-energises,
after the On Time Period that is set in
Relay Setpoint 1 (P213, 223, 233)
