No idea why the thermostat calls for heat when I set the Thermostat to off . I have also it set to 60 degrees . The house tonight got to 75 degrees and had to shut the boiler off . I have also disabled the learning option . I have restarted and reset the whole thermostat . Nothing seems to work . I’m very disappointed in this product . It seems like it happens a lot to other people . If someone has any suggestions pls let me know before I return this product .
