One Master Valve - Two Controllers - Hunter Hydrawise HC Owner's Manual

One Master Valve - Two
Controllers
There are many times when two controllers are being supplied from a single POC (point of
connection) or source of water. Hydrawise-ready controllers can be connected to a single
master valve using a isolation relay (part number REL2). This device will allow for two
controllers to share the same master valve with out any issues.
The few limitations include:
Only one controller can operate at a time.
A delay of at least five minutes between the operation of controller #1 and controller #2
is desirable.
Electrical alerts will apply for each controller.
