Hello and . We are glad to have you join us here and we look forward to reading of your adventures and experiences. I am sure you will enjoy the website and forums. Good luck, stay safe and keep us posted.
Did you allow the new T'stat to program itself before trying to activate it? You may want to reset the T'stat. Make sure the switch is in the off position unplug the T'stat data cable, wait a minute and then plug it back in. If I remember correctly you push the mode and zone button simultaneously (Do Not Turn On the T'stat) and wait for it to find all the parameters. To answer your questions, the furnace does get its control power from the roof units.
