Master Valve or Pump Start Relay
Connect an optional master valve or pump start
relay
SST timers support the use of a master valve or pump start relay.
A pump start relay connects to the timer the same way as a
master valve, but connects dierently at the water source.
Using a direct burial cable, connect one of the wires from
the master valve (or pump start relay) to the timer termi-
nal marked MSTR VALVE.
Using a direct burial cable, connect the remaining wire
from the master valve (or pump start relay) to one of the
timer terminals marked COMMON.

Additional instructions for connecting a pump start
relay
To avoid possible pump damage, connect a short jumper
wire from any unused zone terminal(s) to the nearest
zone terminal in use.
Example: if a 4 zone model timer is in use with only two
zones connected, route the terminals for zones 3 and 4 to
the nearest active terminal (in this example, zone 2).

WARNING: Make sure that the total draw of the master
valve (and/or pump start relay) plus the draw of the valve
does not exceed 650mA at 24VAC, 60hz. Note that the
timer does NOT provide main power for a pump.
