A:Answer Hi. Unfortunately, it is not possible to program the thermostat to power off, but you can set it to OFF mode by using the controls on the screen and remotely via the Total Connect Comfort app and web portal. If the thermostat needs to be powered off completely during the renovation, you can do so by disconnecting the faceplate from the wallplate or shutting off the circuit breaker for the HVAC system. For further assistance, please feel free to reach out to us at 1-800-633-3991, or through Twitter and Facebook under Honeywell Home. -Jerry
