RESET BUTTON

If the thermostat does not respond when keys are pressed, or the thermostat is not operating properly, you may use the reset button located on the back of the thermostat body (see fig. 2). Thermostat programming and configuration will not be affected by pressing the reset button. However, the clock will need to be reset.

RESETTING THERMOSTAT CONFIGURATION AND PROGRAMMING

The thermostat can be reset back to default programs and configuration. Removing power from the thermostat will not reset it, because the default settings are maintained in permanent memory. Before resetting the thermostat, you may want to make note of the previously selected configuration and programming. You must reconfigure and

reprogram the thermostat after resetting it using this method.

To reset the thermostat, press and release PROGRAM RUN , then press the FAN ,

TIME BACK and buttons at the same time. This will reset the thermostat to factory default programs and configuration. The display will momentarily go blank, then all segments on the display will momentarily be shown. The thermostat will then go into the HOLD mode and will maintain factory preset temperatures.
