Control Relay Configuration
When a relay is set up as a control relay there are two setpoints that must be defined; the on
setpoint and the off setpoint. The relay will be energized when the level reaches the ON
SETPOINT value and the relay will be de-energized when the level reaches the OFF
SETPOINT value. This is simple enough but there are other factors to consider before
setting the relays up.
