ZONE VALVES

ZONING FOR WATER VALVES

Connect Z to 1, T1 to 2, and T2 to 3 on water zone valves as shown. Refer to sheet packed with water valves for complete wiring information. For water valves other than White-Rodgers, consult the valve manufacturer for wiring details.

ZONING WITH CIRCULATORS

All wiring should be done in accordance with local and national electrical codes and ordinances.

This diagram shows connections for either a line voltage or 24V Manifold Gas Valve. This diagram may also be used on Type 668 Kwik-Sensor Oil Burner Controls by wiring to B1 and B2 terminals as shown on preceding page.

NOTE

This diagram is not recommended for normal stack- mounted oil burner controls because rapid cycling of the low limit-circulator control may cause the oil burner control to lock out on safety.
