Install Master Valve or Pump Start Relay
This example shows a typical Master Valve connection. A Pump Start Relay connects to the
controller the same way, but connects differently at the water source.
STP Plus Controllers allow a Master Valve
or Pump Start Relay to operate whenever
a valve is operating (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 Control Relay.
NOTE:
The controller does NOT
provide main power for a pump.
Connect the color-coded “hot” wire
from the Master Valve (or Pump Start
Relay) to the controller terminal
marked MSTR VALVE.
Connect the common wire (usually
white) from the Master Valve (or
Pump Start Relay) to one of the
COMMON terminals.
