ADDENDUM For Variable Speed Furnaces used with Two Stage Cooling
Two-Stage Furnaces with Variable Speed Blower,
Single-Stage Furnaces with Variable Speed Blower
The furnace is supplied with the yellow “Y1” and blue “Y2” connections attached to the "Y" terminal on
the furnace control board. For single stage cooling operation, leave the yellow and blue wires in place.
The indoor blower will operate at the CFM called out in the "High" column.
For Single Stage Heat and Two Stage
Cooling
When installing this furnace with a two stage
condensing unit, remove the blue “Y2” wire from
the control board and connect to the thermostat.
Connect a field supplied wire from the yellow
“Y1” to the thermostat and the condensing unit,
and another wire connected from “Y2” on the
thermostat to “Y2” on the condenser. (See
Figure 1).
For Two Stage Heating and Two Stage
Cooling
When installing this two stage furnace with a two
stage condensing unit, both the yellow “Y1” and
the blue “Y2” connections remain on the furnace
control board. Connect a field supplied wire from
the yellow “Y1” to the thermostat and the
condensing unit, and another wire from “Y2” on
the thermostat to “Y2” on the condenser. (See
Figure 1).
Follow all start up procedures outlined in the instruction manual.
