INTRODUCTION
The Toro Lawn Dial Outdoor Irrigation Controller
is a programmable electronic timer that controls
the watering of six or eleven stations (depending
on the model) using remote solenoid valves.
In a typical irrigation system, there is a Master
Valve (MV) which is switched on whenever one of
the Station Valves (SV) is on.
The Controller is also suitable for use on water
supplies derived by pump from a bore or a dam.
In this case, the Master Valve control line is used
to turn on a Pump Start relay which controls the
power to the pump. The Pump Start relay is not
supplied with the controller. A Relay should be
installed by a qualified electrician.
Note that the Lawn Dial Controller will not power
the pump; it will only control an auxiliary relay
that switches power to the pump.
