Home / Wiring / 4iE Smart WiFi Thermostat

Do I need to use the WiFi on my smart thermostat?

If you have a smart thermostat you will need to connect to WiFi to hold thermostat settings.

Warmup 4iE smart WiFi thermostats are designed to be connected to WiFi. For this reason, many thermostat settings are stored and backed up via an internet connection. If you find that your settings are not advancing, you want to check your thermostats’ WiFi connection.

If you do not wish to connect to WiFi, the non-WiFi 4iE-03 is available in both black and white.
