Master Valve
Timers support the use of a master valve.
Using a direct burial cable, connect one of the
wires from the master valve (or pump start relay)
to the master valve terminal (M).
Connect the remaining wire from the master
valve (or pump start relay) to the common
terminal (C).

Pump Start Relay
Pumps are used in some places to draw water from a
well or other source. If you are activating a pump from
the Timer, you must install a pump start relay.
A pump start relay connects to the Timer in the same
way as a Master Valve, but connects dierently at the
water source.
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).
