Heating & Cooling - HVAC

When designing a home theater, a commonly overlooked area is the heating & cooling your home theater.  Since you'll have a group of people with a hot TV/projector, it is important to have a way to control your theaters temperature, even if you're tapping into an existing HVAC system.  See below for several different products designed to make it easy to uniquely control your home theaters temperature.

 Motorized Vents and Zone Dampers

Motorized Vent Register

Motorized zone vent register in Brown

Motorized zone vent register in Taupe

The Motorized Vent Register is an easy way to provide dedicated temperature control for your home theater - for either new or existing rooms!  

It is designed to be used with regular wall-mounted thermostat to eliminate over-heating and over-cooling problems in: home theaters, bonus rooms, room additions, seldom-used rooms, and basements - basically allowing you to create a unique thermostat control for any desired room. Simply run a 2 wires from a standard thermostat and from a 24 volt transformer (available below), and you are in business - no zone controller is needed!  Even if your room is already built, you can easily add the motorized vent register by simply replacing your existing vent and running the wires on the wall/baseboard surface.

This powered vent can also be used in place of standard zone dampers with a zone controller when duct work is not accessible,  making it easy to install an existing room.


See our Motorized Vent Register details for FAQs & Installation details.

Stand-alone Zone Dampers

Stand Alone Zone Damper

Our stand-alone zone damper is a two position  zone control damper assembly designed to solve isolated over-heating and over-cooling problems for rooms such as home theaters.


This damper can be used to control a single room, or by using a number of dampers, zone multiple rooms. The duct sensor, auto changeover control and zone damper motor are pre-wired at the factory. Simply run two wires from a 24 volt transformer, three wires from the thermostat, and you are in business - no zone controller is needed!


Included on the zone damper is an automatic duct sensor that senses whether there is warm air or cool air in the duct.  If the thermostat is calling for cooling and the the sensor determines there is cool air in the duct, the damper will open (otherwise it will remain closed).  Similarilly, if the thermostat is calling for heat, and there is hot air in the duct, the damper will open.

  Powered open / spring return closed
  Auto changeover
  Minimum position adjustment
  24 Volt AC motor
  No control panel required
  A slave damper can be used to control a second duct run from the same thermostat
  Use only with low pressure air systems (1" of static pressure or less)

Retrofit Damper

Retrofit damper

The Retrofit Damper is an easy & inexpensive way to zone an existing home or building. With traditional round zone dampers, it is required that a section of the existing ductwork be removed and the damper be installed in this section. With the Retrofit Damper, a small 1 slot cut into the existing ductwork is all that is required. Then it is simply fastened to the ductwork with four zip screws. Installation is that simple!

Another benefit to the Retrofit Damper is its actuator. It uses a high torque, low power actuator. This allows up to 20 dampers to be wired directly to almost any zone control panel (no additional relays or transformers required). Installation is that simple!
