GoControl Smart Thermostat

If you have gone through our best Z-Wave thermostat review, you would have realized that Z-Wave thermostats are among the cheapest in the market. This is so since the thermostat tends to send much of the smart operations to the Z-Wave hub.

The thermostat will work on standard HVAC systems and heat pump systems with 3 stage heat and 2 stage cool. The thermostat runs on 4 AA batteries and will be compatible with most Z-Wave hubs. The thermostat can work as a standalone programmable thermostat but will work best with the Z-Wave hub.
