It includes a 24VAC/20VA plug-in transformer and supports 24V thermostat compatibility, enabling automated or manual control of airflow to individual rooms. Its normally closed design conserves energy by blocking airflow when unpowered, while the patent-pending adjustable coupler enhances fresh air intake and draft prevention. Ideal for millennial professionals seeking smart, cost-efficient climate control with seamless integration into existing systems. ## Description Enjoy having complete electronic control of which rooms your HVAC system heats or cools with this 24V Motorized Duct Dampers that can be automated (or manually controlled) in a variety of ways. These motorized dampers can be configured to open and close partially or completely depending on your application. These units are compatible with our popular RCS HVAC Zone Controllers (see our 24V Electronic Duct Dampers for other compatible units). 24V Hardwired power supply included. These models offer the flexibility of being controlled with any mechanical thermostat, an appliance module (when used with a plug-in 24V AC power supply), or an X10 Universal Module (all sold separately). With electronic duct dampers, an appliance module and any X10 timer, you can reduce your heating/cooling expenses by cutting off airflow to unoccupied rooms during work hours. Or, if you want a room to be a little colder or warmer than the rest of the rooms in the house (i.e. grandma and grandpa's bedroom), any mechanical thermostat can close the damper when a pre-specified temperature is reached. The 24V Motorized Dampers are available for 6", 8", 10" and 12" duct diameters, and can be ordered in normally-open or normally-closed configurations. When no power is supplied to the Normally Closed unit, the damper will be closed. When no power is supplied to the Normally Open unit, the damper will be open Review: I'm a general contractor and I can tell this product is well made , it comes with a transformer with its on plug to decrease power to low voltage with connectors on the side for power in and out towards power to the equipment. If you want to put this dumper on your duct lines inside framing ,DO IT BEFORE YOU CLOSE ACCESS TO IT OR JUST PUT AN ACCESS PANEL FOR FUTURE SERVICE ALSO NEED TO TRANSFER THE LOW VOLTAGE WIRE FROM THE BACK OF THE PLUG TO YOUR TERMOSTATE OR separate DEVISE USED TO CONTROL only THE DUMPERS . TOO BAD I HAD some WALLS AND CLOSED AND HAD HARD TIME INSTALLING IT [ low voltage wire do not come in package and also will need an outlet accessible to plug in ( you decide where to plug it according with how long LOW VOLTAGE wire you will use . It can be a DIY if you feel comfortable With it. Mine was meant only to maintain more heat flow on first flow when gets cold and close when gets hot so i get more cold air upstairs when hot Review: I installed this in our Heat Pump system. Our addition rooms would get too cold with the cold on, even with the registers closed the rooms. The damper was installed and adjusted to restrict the air flow down and now the rooms stay comfortable. This unit works great, it was very reasonably priced and for what I needed it worked perfectly. ## Features - ECONOMIC SOLUTION – Protect your comfort & your wallet by limiting heating and cooling expenses in your space.
