I have a room this fed heat and cooling through a duct that has a t-stat controlled motorized damper built into it. The Damper is the "Normally Opened" version. Here is a link to it.
I could have used the "Normally Closed" version and the problem I am about to describe would go away. I chose the "Normally Opened" version b/c the I estimate that 90% of the time, the damper will need to be opened.
The problem is that all t-stats I find work on the assumption that I am using a "Normally Closed" damper. Thus, for it to work properly for me, I need to put the t-stat in the "COOL" setting in the winter and "HEAT" in the summer. Obviously this is non-intuitive and not a preferred solution.
So, the options I see are 1.) Replace the damper w /the Nomally closed version. 2.) Live w/ the funky t-stat situation 3.) Find a t-stat that works in reverse from the way all the others do [NOTE: I have yet to find such a t-stat].
Other ideas? Anone know of such a "reverse" t-stat?
BTW, all work being done is by a pro.
