3. Troubleshooting
If the WPT exhibits incorrect or suspect behavior after battery replacement, perform the
following steps. Examples of such behavior could be: non-responsive buttons, erroneous
setpoint limits, inaccurate ambient temperature or excessive motor movement.
1. Remove both batteries from the WPT thermostat.
2. Press and hold the OVR button until the segments on the LCD are no longer visible.
3. Let the thermostat sit for 30-45 minutes to fully discharge all components. This will
default many of the operating parameters of the thermostat to factory defaults.
4. Re-install the batteries and follow the steps in section 2.1.
