The wood heats fans are not strong enough to push the heat throught the entire system. Oh, and the duct system is 90 years old, there are NOT up/down stairs zones, its all on or all off.
Help with were I'm being vague so I can try to explain it better! I'll take pics of units downstairs when i get home tonight. thanks
Ok, now im really confused.
You said this is a farm house, so does the unit only control the A/C and the heating aspect is handled by the wood stove?
Im guessing this means when you are in "heat mode" and the room with the t-stat senses a low temp it will just turn on the blower motors to pump in heat from the stove until it warms up?
But then you state another motor pumps heat into the unit, from the wood stove, which is the only way to get it upstairs. And you are having trouble getting heat upstairs?
The simplest way to do that is to have all the blower motors come on at once, but you dont want that to happen? So they next easiest way is to get another tstat setup upstairs to control the second blower motor, but you dont want that either?
Then only other way would be to set up a light switch or something hooked to a blower motor upstairs. So when yo uflick it on, it pumps heat into the ducts leading upstairs.
Putting two t-stats next to each other, controlling the same unit, will only make your system worse.
