Stelpro released a new thermostat from its Ki series, the Stelpro Ki ZigBee Thermostat (STZB402+) aimed to control baseboard heaters, convectors and Fan-Forced Heaters up to 4000W powered at 240V (also works up to 2000W at 120V).
This model also features the “Off” mode, which prevent any heating.
When using this mode, please keep in mind the freezing risk, and be warned that the thermostat is still powered.
Even in “Off” mode, there are risks of shock hazard if you service the thermostat without turning off the breaker.
To this date, SmartThings did not yet publish Stelpro’s device handler for the STZB402+, so you may get the code here:
