“I was installing a Heat Pump with oil furnace as the auxiliary source and this thermostat was recommended by my HVAC contractor. I am happy with the thermostat. It's very stable and never failed. The thermostat turns my Heat Pump when the outside temperature is above 40C and switches to the oil furnace if the temperature is 40C and lower. Plus, I can use my smart phone to manage the thermostat remotely because it's connected to my network with Wi-Fi.I am happy with making this choice.”
“We have a vacation home in a cold climate and worried if the the heating system was working properly. The main concern was if the heat failed the water pipes might freeze.Using the app for the thermostat we can now check regularly on the indoor temperature. A great feature is that before we go to the house the temperature can be raised during the winter and the air conditioning turned on in the summer. When we get there the house is at the comfortable temperature.The price paid was much lower than what our heating company quoted.The install was done by our heating company therefore the "Easy To Install" was not rated.”
“First, make sure you have a C-wire on your existing thermostat, or know how to wire one (not hard). Key piece of info- if you have split systems (AC & Heat) *the C-wire must come from the AC*. Luckily I saw that footnote in the instructions.Once I had it wired, setup was straightforward except the WIFI WOULDN'T CONNECT. This is apparently a common issue with Honeywell thermostats (Google it) they have trouble connecting to some routers for no apparent reason. Honeywell support was extremely disappointing, they wash their hands of it and tell you to contact the router manufacturer. (ASUS RT-AC88U)After trying dozens of times (entering the password is a PITA each time!) I had to disable an advanced wireless setting in my router called "AIRTIME FAIRNESS". This should not be an issue for a modern device.Disabling AF can slow down other devices on your router, so at some point I will try to turn it back on and see if the thermostat stays connected.The main reason I got this thermostat was for the dehumidify feature, which (as another reviewer mentioned) is great for husband/wife thermostat wars. It allows the AC to come on below the temperature set point if the humidity is still high. So your spouse can set it for 75, but it can run down to say 72 if it's above 60% humidity (both adjustable). Good compromise.The remote wifi control is icing on the cake...”
