DISPLAY in either mode. Error codes will not show on the remote thermostat even when in remote thermostat

ATTENTION
DO NOT place heater back into “00” default factory setting without wall thermostat connection components.
Failure to do so may cause the unit not to function properly.
Remote Thermostat Mode (Optional Accessory)
A remote thermostat can be installed for the furnace with the Remote Thermostat Installation Kit (Part # 204000045).
Once installed, the furnace must be placed in Remote Thermostat mode by following the steps below:
1. Ensure the furnace is plugged in but is turned OFF.
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.
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.
ATTENTION
Do not unplug the furnace within two hours of entering Remote Thermostat
mode. This will cause the furnace to revert back to Control Panel mode (default).
00 - Default Factory Setting
01 - Remote Thermostat Mode
02 - Control Panel Mode
ATTENTION
The remote thermostat will NOT control the heaters ability to power on or power down.
This must still be done by using the ON/OFF button of the heater.
