Connecting a Master Valve or Pump Start Relay
To use a master valve which operates throughout the watering cycle, connect one
solenoid lead to “MV” terminal and the remaining lead to the “VC” terminal. Refer to
Figure 3 on page 7.
Note: The master valve must be equipped with a 24 V a.c., 0.2 A, 5VA solenoid.
To use a pump start relay, connect one relay lead to the “MV / Pump” terminal and the
remaining lead to the “VC” terminal. Refer to Figure 3, page 7.
Note: The pump relay should have a nominal coil voltage of 24 V a.c. at 0.375A
maximum. The controller should not be installed within 5' (1.5m) of a pump, pool
equipment or other motorized equipment. Consult with a pump dealer for detailed
instructions.
Connecting a Rain Sensor
The Rain Dial Plus is designed for use with a normally-closed rain sensor or rain
switch. Refer to page 10 for important rain sensor operation information.
1. Route the two wires from the sensor into the cabinet through the valve wire opening.
2. Remove the jumper wire from the two Sensor terminals. Connect the sensor wires to
the terminals in either order. Refer to Figure 3, page 7.
Note: Refer to the instructions supplied with the rain sensor or switch for additional
installation information.
Connecting the Power Source – Indoor Model
After you have mounted your controller and completed all field wire connections, route
the two leads from your transformer through the small hole provided in the cabinet
bottom and connect to the terminals labeled “24 VAC”. Refer to Figure 3 on page 7.
Close the control module and plug the transformer into a wall outlet.
Note: The plug-in transformer is supplied with the domestic controller models only.
Connecting the Power Source – Outdoor Model
Outdoor controller models have a built-in transformer which must be
connected to a grounded AC power source.
Note: Australian controller models are equipped with a plug-in power cord.
For installation, insert the plug into a grounded 240 V a.c. 50 Hz outlet.
