Remote outdoor sensor
The remote outdoor sensor (Part No. 9025i) can be used to aid in the comfort of your home or simply as a sensing device to
inquire about outdoor temperature.
With your heat pump system, the remote outdoor sensor helps determine when to turn on the second stage heating for
optimal comfort.
Installing a remote outdoor sensor
The remote outdoor sensor should be installed on the northern wall of your home, away from direct sunlight or other heat
sources that may affect its sensitivity.
Time of Day Zoning
You may want your thermostat to use the temperature in your living room during the day and the
temperature in your bedroom at night. Assuming the thermostat is installed in your living room,
you would install the remote sensor in your bedroom. You would then use the Schedule Menu to
establish a two-event day (Wake and Night). Then make a setpoint of 70° for your living room
from 6am to 10pm. Another setpoint of 65° could be made for your bedroom during the hours of
10pm to 6am.
Faulty Sensor
If a remote sensor fails or is disconnected, the thermostat defaults to the built-in local sensor (when you have selected
Remote as the sensor choice).
NOTE: Remote Failed also appears on the main screen to indicate a remote sensor failure.
