Will the ZEN Thermostat work without batteries?

No. The ZEN Thermostat needs 4 AA Alkaline batteries installed in the display at all times.

If you have a "C" wire on your current system, this will power the system indefinitely and you won’t need to replace the batteries.

If you don’t have a C wire, the 4 AA Alkaline batteries will keep ZEN powered for approximately two years.
