WIRING

All wiring should be done according to local and national electrical codes

For best connections, use #18 Thermostat wire. #16 will also work satisfactorily.

Make connections to screw terminals according to wiring dia- gram.

NOTE: To check motor operation without thermostat con- nected, jumper 4 to 5 to open valve; jumper 5 to 6 to close valve.

If the boiler manufacturer recommends a wiring diagram, follow his instructions. If none are available, the following diagrams show suggested circuits for Type 1311 Water Valves in conjunc- tion with other W-R controls.

A 40 VA transformer will handle up to four (4) water valves. A 20 VA transformer will handle up to two (2) water valves.

!CAUTION

Do not attempt to wire two or more zone valves in parallel to operate from a single thermostat. (If valves are wired in parallel, the motors may run continuously, due to feedback between the motor holding circuits.)
