comfort and energy efficiency or a built-in 1 to 8-
hour timer. The fan speed can be set from the
remote.
Or uses the built-in 1 to 8-hour timer.
Wireless range is 125’ in a home or building.
Controls the whole house fan wirelessly from

The WHF can be controlled by temperature or by a built-
in timer. In Temperature Control, the RT2 wireless
control turns the fan on when the room temperature rises
above your setpoint temperature or turns the fan off
when the room temperature drops below your setpoint
temperature just like your air conditioner. In Timer
Control, the user sets a number of hours to run the fan
using the built-in 1 to 8 hour timer. When the time
elapses, the fan turns off.

The RT2 includes a Safety Timer option that is used in
Temperature Control. The option is defaulted to On and
is only displayed if Temperature Control has been
selected in the previous option. The Safety Timer
automatically turns off the fan after 12-hours to avoid
inadvertently leaving the fan on during the day. This can
be beneficial if someone forgets to turn EconoCool Off in
the morning.

When EconoCool is On, the RT2 activates the WHF
when the indoor temperature is 1 degree warmer than
the WHF cooling temperature. The WHF is turned Off by
the RT2 when the cooler outdoor air has lowered the
indoor temperature 1 degree below the WHF cooling
temperature. The WHF will cycle On and Off as needed
to keep the space comfortable.
When an optional outdoor temperature sensor is
installed, the WHF will not be activated if the outdoor
temperature is above the outdoor temperature limit.
This improves energy efficiency and comfort by inhibiting
WHF operation when the outdoor temperature is too
warm to provide cooling.
Press the UP or DOWN key to
change the Outdoor Temperature
Limit and then press the ENTER

Connecting FC2J to RM2 Radio Module
The FC2J and RM2 are connected using the 7-foot RJ11
cable provided with the FC2J. The RM2 can be attached
to a surface (not metal) using the two mounting tabs or
left suspended by the RJ11 cable.
Plug one end of the cable into the FC2J and the other
end into the RM2 Radio Module. The RT2 wireless
control is now ready to communicate with the RM2 and
control the FC2J.

Installing the Outdoor Temp 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 inhibit WHF operation when the outdoor temperature
is too warm to provide cooling.
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.

Setting ADR Number on RM2 Radio Module
The RT2 and the RM2 are factory set to FAN 1. If only using
one WHF, proceed to Option 2. Up to 8 WHFs can be used in a
home. Each fan must be set to a different Fan number so that
the RT2 only controls the WHF with the corresponding number.
The fan number must be set at the RT2 and at the RM2.
When neighbors are using the wireless RT2 thermostat, the
RT2 and RM2 must be set to different ADDRESSES (ADR) if
the homes are within 300 feet on one another. This insures
that an RT2 does not control a neighbors WHF.
Use a paper clip to push the
internal switch. When
pressed the LED will blink
green once, pause, blink
twice, etc.
For example, to set the fan to
number 3, release the switch
after the LED rapidly blinks 3
times.
