Z1
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.
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.
