Step 1
Connect the color-coded “Hot”
Wire from the Master Valve (or
Pump Relay) to the Controller
terminal marked MSTR VALVE.
Step 2
Connect the Common Wire
(usually White) from the Master
Valve (or Pump Start Relay) to
the Controller terminal marked
COMMON.
NOTE: STPi Series 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 also install a Pump Control
Relay.
This example shows what a Master Valve connection would look like. A Pump Start
Relay would connect differently at the water source.
