Loosen the screws holding the thermostat base or subbase to the wall, and lift away.
Disconnect the wires from the old thermostat.
Tape the ends of the wires as you disconnect them, and mark them with the letter of the terminal for easy reconnection to the new thermostat.
Keep the old thermostat for reference purposes, until your new thermostat is functioning properly.

Installing the Outdoor Sensor
The Outdoor Sensor measures outdoor air temperature and sends this information to the thermostat; it measures temperature with a range of
-40 to 127 F.
4
The Outdoor Sensor should be connected to the thermostat using solid conductor CAT 5, CAT 5e, or CAT 6 type network communication cable.
This is an unshielded cable with four twisted pairs of 24 gauge solid wire;
DO NOT use stranded cable. The cable length should not exceed 250 feet. If less than 75 feet of cable is required to connect the thermostat to the Remote Sensor, a three conductor thermostat cable (18-24 gauge) may be used; this cable is NOT suitable for any length greater than 75 feet.
IMPORTANT: Do no use shielded wire. Do not run sensor wiring in the same conduit as the 24VAC thermostat wiring. Electrical interference may cause the sensor to give incorrect temperature readings.
See the Outdoor Sensor accessory for further details.
