Great JOB thank you for the information in regards to wiring Error message. When contacting Honeywell, they could not advise on how to work with the wiring layout. Your explanation saved me from getting rid of the unit. Perfect... Thanks Again
very helpful i had the exact same upgrade from a T4 luckily all the wiring was an exact match for a switch and no errors. Happy i didnt have to take out the old T4 connecting mount
When checking the settings, your video is assuming that the previous owner, or whoever installed this, inputted the correct settings to begin with. so how do you know if the settings are correct before you write them down and try and copy those on a new thermostat?
I am curious about the controller that displays the operation of your heat pump. What make and model heat pump do you have? If that is a zone controller, what make and model is that? Thank you.
