Wiring FC3J to 2-Speed ECM WHF
For 2-speed ECM WHFs, the yellow wire is not used and
should be cut off at the PC board. Use wire nuts to connect the
FC3J wires to the WHF wires and the incoming 120VAC power
wires. Orient the FC3J and electrical box as shown.

Optional Outdoor Temperature Sensor
The optional TS3 Outdoor Temperature Sensor should
be installed under the eaves of the home and out of
direct sun light. The outdoor temperature sensor is used
to delay WHF operation when the outdoor temperature is
too warm to provide cooling.
RM2 Radio Module
Use 2-conductor AWG 20 to 24 wire to connect the
temperature sensor to the ODT terminals on the RM2
Radio Module. The sensor is not polarized.
