Thermostat went off line after about 2 weeks and changed the schedule to cool to 50 degrees at night. Would not reconnect to the WiFi. Had to go back to manually changing the temp at night/morning.
The thermostat looks good and works well if you don't want to be able to control the temperature swing or cycle rate. I consider this a serious flaw. I cannot fathom why a top quality manufacturer like Honeywell would not permit the users access to this adjustment. It would cost next to nothing to implement. In case anyone is not familiar with the temperature swing option, it is the ability to control how much the indoor temp is allowed to vary from the set point before the heat (or AC) turns on. With the Honeywell it is fixed internally at 1 degree and cannot be adjusted. This causes my air conditioner to vary at least 1 degree and sometimes as much as 2 degrees between on/off cycles. The result is that since installing the Honeywell I notice my house is less comfortable and seems more humid at times. My previous thermostat (Lux) the AC was more consistently comfortable all day. I will have to stick to Lux products since they do allow for this important feature. Too bad, the Honeywell seems to be a great product otherwise.
Thermostat works well with good WIFI connection. Using on a 3 heat 2 cool Bosch geothermal unit. Also, utilizing Honeywell Total Connect app That is working well.
So nice to have WiFi stats that I can control form my phone if someone forgets to turn the heat or cooling up or down and also nice to have the schedule option that the temp reverts back to set back temps if someone forgets to turn the temp back.
