This example shows what a Master Valve connection would look like.
A Pump Start Relay would connect differently at the water source.
Master Valve or Pump Start Relay
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

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
