Can I upgrade to the 6iE?
6iE Smart Thermostat
Yes! Upgrading an existing Warmup thermostat to the 6iE is an easy task for a licensed electrician. Mounting direction may vary, so a face plate is available to correct this if necessary. The 6iE is a vertical mounting thermostat.
The old thermostat and the new thermostat should be wired exactly the same. Once a new unit is in place, the user can register it under an existing MyHeating account if they have previously had a 4iE Smart WiFi thermostat.
