QuestionWhat if my WiFi gets turned off will this still work and will I still be able to see it on my phone app
Asked 5 years ago by 107dal.
- Answer If your Wi-Fi is off, you will have to manually change the thermostat. You will not be able to connect to the thermostat with your mobile device if the thermostat is not connected to the internet. If the power surges or connection is temporarily lost, the thermostat will automatically reconnect. If your Wi-Fi shuts off permanently, the thermostat will not be able to connect to the network.

QuestionI would like to purchase this thermostat to install on my Mr. Heater Big Maxx heater for my garage. Some thermostats do net let you set the temp below 50 degrees. Can this thermostat be set to 40 degrees? I want to be able to set it below 50.
Asked 5 years ago by Tony.
- Answer I can set the thermostat down to 40F for heating. Obviously I couldn't test the furnace at the moment but the thermostat appears to be able to handle that low temp.

QuestionHow to dim the display
Asked 5 years ago by Kezi.
- Answer Kezi, Tap settings, then tap the down arrow until preferences can be seen, tap preferences, then locate the backlight option. Under this option, you can choose the backlight setting in rest mode. Meaning, the screen will full bright when touched, and after a delay will tike out to your preset backlight setting Hope this helps!

QuestionI have a Honeywell Proseries thermostat control which can be easily removed leaving the "base" intact installed on the wall. Can I obtain a Honeywell smart thermostat that can just be plugged into the existing base?
Asked 5 years ago by BARK.
- Answer You may end up buying and installing C Wire Adapter for Thermostats 24 Volt Transformer Compatible with Nest Honeywell Ecobee Emerson Sensi Smart Wifi Thermostat . And no its not to simple. Best buy won't tell you that nor Honeywell. Go to you tube and watch how to install it. If you already have 24v C wire the it should take you about 15 minutes max. If you don't about 1 to 3 hours

QuestionI’m replacing a heat pump with W, B, G, R, O and Y on old T874R1749 anyone know how to wire this on new thermostat? Note O and Y both have yellow wire can’t tell if jumpered or not
Asked 5 years ago by BigGuy.
- Answer It should, o and b are your reversing valve for the heat pump, however I did not see anything about a c, for the best operation it should have c hooked up as well. It actually wont work without the c wire.
