Re: M 201 Issue

Hello. If the heating system won't turn OFF, that is if heat keeps being delivered even when you don't want it, set the thermostat to its lowest temperature setting and wait three to five minutes. Or if your thermostat has a HEAT OFF COOL or FAN AUTO OFF control, set the control to OFF or COOL.
