WARNING:
Make sure the power transformer is unplugged
while making connections to any station or master
valve/pump output terminal.
WARNING:
A maximum load of 6VA, (which is equivalent to one Lawn Genie,
Hardie, or Richdel valve), may be connected to each numbered
valve terminal. A maximum load of 12 VA may operate
simultaneously (i.e. one valve at a time in addition to the master
valve).
The relay coil must be rated for 24 VAC at 250 MA maximum. The
relay contacts will be connected to the pump start terminals and
must be rated for use with your particular pump. (See diagram). In
addition, a high pressure relief mechanism is recommended. See
your pump dealer for more information.

Connecting a Pump Start Relay
The controller must be mounted at least 15 feet away from
both the pump start relay and the pump. When a pump is to be
operated by the controller, a pump start relay must be used. The
relay coil should be connected to the master valve output
terminal marked MV and the common terminal C at the controller.
W A R N I N G :
If a pump start is installed you must use a
jumper wire from each unused terminal screw to a numbered
terminal screw in use. This is critical to avoid damaging your
pump, (i.e. running it dry, which may burn out the pump
motor.) Neglecting to jumper all unused terminal screws may
seriously damage your pump during default program
execution.
