Q: QuestionHow to dim the display

Asked 5 years ago by Kezi.

• A: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!

Q: 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.

• A: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
