Master Valve or Pump Start Relay Installation
• Connect the color-coded "hot" wire from the Master Valve
or Pump Start Relay to the Timer terminal marked MASTER
(MSTR) VALVE.
• Connect the common wire from the Master Valve or Pump
Start Relay to the common wire coming from the station
valves. This wire connects to the Timer terminal marked
COMMON.
• To avoid possible pump damage, connect a short
"jumper" wire from any unused station terminal(s) to the
nearest terminal screw in use. For example, for a
6–station timer with only 4 stations in use, route stations
5–6 to the nearest active station (in this case, station 4).
USER TiP:
Make sure that the total draw of the Master Valve or Pump Start
Relay plus the draw of the valve does not exceed 0.650 Amps at 24 VAC, 60 Hz.
This Timer does not provide the main power for a pump.
SST Series Timers allow a master valve or pump start relay to operate whenever a valve is operating
STOP
(pumps are used in some places to draw water from a well or other source).
If activating a pump from the Timer, you must also install a Pump Control Relay, such as Rain Bird's
PCR-1. The PCR-1 can activate most 120– or 240–volt pump motors up to 2 horsepower.

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