INSTALLATION INSTRUCTIONS
PUMP HOOK-UP CONNECTIONS
Do not attempt to drive a pump starter directly from the controller.
Pump start is provided by connecting one side of the coil of a suitable
relay to the Master Valve/Pump Start output of the controller and the
other side to the controller common.
For systems supplied with water from a pump, unused stations must
be connected back to the last used station to eliminate the possibilty
of the pump running against a closed head. Failure to do so could lead
to pump damage.
The diagram shows an 6 station controller with 4 active stations
(valves):
Unused stations must
be linked back to the
last used station.
Use insulated cable.
