Programing done by AC installers but they had difficulty and sent another to get wifi working. Then i realized fan was running on heat mode but don't want as I have hot water heat. Called 800 for customer rep who walked me thru a reprograming of my heat profile, very patient. Good but hope i don't have to do any programing on it in the future...
We are snowbirds and the ability to track our home conditions is very important. Troy from Trademark Mechanical was great to work with, in and out in an hour installed and on line, with a solid warranty.
It took about 70 attempts to connect the thermostat and the app initially. I gave up for 6 months and tried again and it worked. My heating guy said this was common.
