Just waiting until Monday to call Tarm, but I noticed the last couple of days my house temps have been lower than normal. It has a couple of degrees colder than thermostat is set at. I checked mt LK 130 thermostat and it had a reading of 68 degrees (I wouldn't mind 68 degrees in VT) but actually it was 31 degrees outside. The settings won't allow me to adjust that much of difference. Just wondering if anybody had any ideas what this could be? Bad outdoor sensor?
