FILM-TECH SCREENING ROOM (CURRENT / PLANO) Plano, TX
This is the override controller that is interfaced into the CA21 automations. Unlike most exhaust systems, this system turns on with the xenon lamp and turns off once the lamp cools down to a predetermined temperature, meaning they aren't extracting air out of the booth when they don't need to be (such as when the other projector is running). It saves electricity (the fan as well as the effect on the HVAC) and also keeps the booth quiet.
