Does anyone make an electrically activated room vent and matching thermostat that is wireless? We have two small rooms in a facility that were balanced, but the occupants of each room have incompatible comfort requirements. What we would like to find is a cheap room vent that could be given high and low set points by each user, and when those set points are reached the vents shut close. We would even be okay with a battery operated vent, with a power out condition resulting in the vent going to open (failsafe to open). Basically any design that lets us give each user some additional control on their personal room environment, with a design that allows a low install cost, would be desired. We tried thermafusers, and they just are not very reliable, and they tend to be a hassle to set, and almost impossible to explain to the end user.
Any products worth recommending for this application?
