Add-A-Zone:The Add-A-Zone is a small accessory box that is used to connect a zone damper to a thermostat to regulate temperature in a small area, creating a "subzone.
Use in areas that only need conditioning occasionally, save energy by allowing conditioning only when required Corrects over conditioning in conference rooms, offices, etc.
Easy to install
Controls up to four dampers for simultaneous operation
Includes digital duct temperature sensor
Add-A-Subzone controls a damper only and does not directly control HVAC equipment
Combine the Add-A-Zone module with a thermostat and a zone damper tp create a single "floating" zone. The Add-A-Zone module looks at the zone demand, checks the duct temperature and decides if the damper should be open or closed.
It's is primarily used to correct over-conditioning problems.
It works by checking the room temperature, the thermostat setpoint, and the duct temperature, then decides if the zone damper should be open or closed. When the room temperature reaches setpoint, the damper will close, preventing overconditioning.
Operates independently of the HVAC system controls.
The supplied duct sensor allows the system to work in autochangeover mode. Includes a ventilation mode.
Works with any standard 24VAC thermostat and a damper models DAMPRRND**INC or DAMPRREC**x** where ** denotes size.
