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

Multi Stage Programmable WIFI Thermostat

Name: Multi Stage Programmable WIFI Thermostat
Brand: Smart Therm

STN715W is the multi stage conventional WiFi thermostat, handling up to 2 heat and 2 cool without heat pump staging. It joins 2.4 GHz and 5.0 GHz networks, works with Alexa, and can be set to 7 day, 5/1/1 or non-programmable. Room temperature calibration lets the installer correct a poor mounting position, which matters more on connected units because nobody sees the reading in person.
