CONNECTING THE BATTERY.................................................................................................
The battery allows you to program the SRC Controller without having AC
power available. However, the battery will not be able to activate any
of the station valves. Electrical power must resume before watering will
continue. The SRC has non-volatile memory which retains all program
information in the event of a power outage.
CONNECTING A MASTER VALVE..........................................................................................
NOTE: Complete this section only if
you have a master valve installed. A
master valve is a normally closed valve
installed at the supply point of the main
line that opens only when the automatic
system is activated.
1. At the Master Valve, attach the common wire to either
solenoid wire of the valve. Attach a separate control wire
to the remaining solenoid wire and make a note of the
color corresponding to the master valve.
2. Route these wires to the controller the same way as the
station valves. The white common wire will still go to the
screw slot marked C. The additional wire coming from
the master valve will go in the screw slot marked MV.
