Connect Pump Start Relay
Connect an optional Pump Start Relay to the ESP-Me
controller.
Pumps are used in some places to draw water from a well
or other source. If you are activating a pump from the
controller, you must install a Pump Start Relay.
A Pump Start Relay connects to the controller in the same
way as a Master Valve, but connects differently at the water
source.
