Thank you for contacting us with regards to your Model 8363 Thermostat. This model has a reset button on the circuit board below and to the left of the display. You can try pressing this button once to see if the thermostat will turn back on. If not, and if removing and reinstalling the batteries does not reset it, the thermostat will need to be replaced. At this point, the 8363 has been discontinued. In our current line of products, the replacement model will be 8463. We recommend that you contact your installer if a replacement is needed.
Please let us know if we can be of further assistance.
