White Rodgers 1F85RF-275 White-Rodgers 80 Series Wireless Remote Sensor Kit Installation Instruction

Once the ideal position is determined, mark mount-
ing holes for the remote sensor. The batteries will
have to be removed from the remote sensor to
access the mounting hole under them.

After mounting the remote sensor, reinstall the
batteries. The remote transmitter will begin trans-
mitting again. Confirm that communication with the
thermostat is still good as describe in step 5.

Perform operation check of thermostat with heating
and cooling systems. Questions on thermostat
operation, see Check Thermostat Operation on
page 13.

Check Remote Sensor operation as described in
Remote Temperature Sensor Information on the
Thermostat Display on page 14.

In normal operation, the remote sensor will transmit
when it senses a temperature change of 3/16 of a
degree from the last transmission or after 10
minutes. The antenna icons will turn on briefly to
indicate the sensor is transmitting and the thermo-
stat is receiving.

The thermostat receiving icon and the sensor
transmitting icon will appear at the same time. The
thermostat display will show SIGNAL and the
strength of the signal, 3 bars high signal strength, 2
bars medium signal strength, and 1 bar low signal
strength. The display will also show the temperature
sensed by the remote sensor.

During the one hour after remote sensor power-up,
the thermostat should be receiving signals consis-
tently (6 signals in one minute).

Once communication has been confirmed, move
remote sensor to permanent location. Do not mount
remote sensor or drill holes to mount sensor yet.

Have someone hold the remote sensor at the
desired mounting location. Hold remote sensor on
the left side to avoid interference with the transmit-
ting antenna on the right side.

Return to the thermostat and confirm that good
communication with the thermostat can be estab-
lished as described in step 5. Ideal consistency is 6
signals in 1 minute.
