WiFi Smart Thermostat 24V WiFi Smart Thermostat Heat Pump Thermostat Electric and Gas Thermostat Non-Programmable Thermostat

Multi Stage Heat Pump WIFI Thermostat

Name: Multi Stage Heat Pump WIFI Thermostat
Brand: Smart Therm

This is STN721W described as the multi stage heat pump WiFi model: dual band connection on 2.4 GHz and 5.0 GHz, Alexa voice control, and heat pump staging plus up to 2 heat and 1 cool conventional. It is deliberately non-programmable, so the operator manages temperature remotely rather than maintaining a schedule in every room.
