Furnace

[RonS]

My furnace had quit working and repairman wants to install another thermostate, out side of the cabnet. I would then have two, one for both ACs and other for furnace. Their must be a better way. He said most likely a wire came loose. Also said to unplug my Charge wizard as batteries getting 14.75 of charge which was too much. I have been using it for years and this is first time any thing w/battery became issue. I will check both 6V batteries now that wizzard has been unpluged overnight and see how much V I have in each.

Any ideas????????? I have not given him the go ahead yet. Dont want an exposed thermostate like entry level RVs.

Thanks........... Ron
