White Rodgers Comprehensive Wiring Diagram for 1311 Thermostat

!CAUTION

To prevent injuries from scalding always drain system before unlatching valve assembly from body.

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.)
