A remote thermostat can be installed for the furnace with the Remote Thermostat Installation Kit (Part # 204000045

Remote Thermostat mode by following the steps below:

2. Ensure the Set back feature is turned OFF.
3. Press and hold the Economy + Up + Program buttons for 2.5 seconds and then release (00 appears in the
display).
4. Press the UP button (01 appears in the display).
5. Press the ON/OFF button; the display will go blank. The furnace is now in Remote Thermostat mode.
ATTENTION
Note: To return the furnace back to Control Panel mode, repeat steps 1-3. At step 4, press the UP button until 02
appears in the display. Next, press the ON/OFF button; the display will go blank. The furnace is now in Control
Panel mode.
