THERMOSTATS

A two-stage thermostat should be used with the WGFM29 and WGFD29 furnace. Two-stage thermostats control which

ﬁ ring rate is used depending on the temperature difference between the set point and the room temperature. A properly

used two-stage thermostat and furnace will maintain a much tighter control of temperature than a conventional single-

stage thermostat and furnace. Two-stage furnaces have “W1” and “W2” terminals. If the thermostat has “Y1” and

“Y2” cooling connections and a single-stage cooling system is used, connect “Y” on the furnace control to “Y1” on

the thermostat.
