So I'm building a dedicated home theater in the basement that will be very tight (for sound isolation). I'm having a mechanical engineer do the calculations now for cfm/velocity etc, but the ideal plan goes something like this:
- Two 6" supplies feeding the theater (from one of two main trunks in the house).
- One 6" exhaust. Since I didn't want to tie into the existing system (for noise reasons), my designer has suggested a technique where we'll use an inline Panasonic Whisper Series exhaust fan (up to 240 cfm) up in ceiling of the hallway just outside the theater. It'll pull air from a ceiling "return" in the rear ceiling of the theatre dumping it out into a hallway/common area where it'll get picked up by the regular cold air return and recycled.
- Furnace fan set to "on" while we're in the theatre to circulate air.
What I'd like to accomplish:
- I'd like to install motorized dampers on the two 6" supplies for two reasons. First, I'd like to be able to close off one of the dampers when the theater is empty, diverting air to the rest of the house. Secondly (and more importantly), I'd love to be able to have the one or both of the dampers close if during winter months the house calls for heat but the theater space is already too warm.
- I'd like to have an easy way to turn on the Pansonic in-line ceiling fan (the one that will exhaust the room) when we're in the room.
I have no idea how this could be wired. I assume I need the two dampers themselves, a controller to control them, and tstat for the theatre. How all this would be wired is beyond me - especially if it has to tie into my existing tstat (in order to know when the heat cycle is on). I'd be happy to pay for some assistance if anyone wants to PM me cuz I'm lost!
