Find the answers to commonly asked questions regarding Arzel products, technology and more!


Which panel should I use?
  • Arzel Zoning recommends the HeatPumPro® panel for any application with 4  zones or less. In light commercial applications up to 8 zones, the AirBoss® panel is a perfect solution. Contact tech support with any additional questions. 



Can I add a zone to an existing panel?
  • Yes, you are able to add additional zones to an existing Arzel Zoning System with the use of an Arzel Slave Board. However, a slave zone cannot turn the equipment on or off by itself. To satisfy a call from the panel a “Slave Zone” piggybacks off of another zone and relies on it to communicate with the system. Contact tech support with any additional questions.

How quiet are Arzel dampers compared to competitor dampers?

Unlike other brands that run on loud Electro-Mechanical motors, Arzel’s silent operating systems are guaranteed to fulfill your customers comfort expectations without detection. 
How well do Arzel dampers seal the duct and stop air flow?
  • Arzel dampers are among the few in the industry that offers a gasket around the perimeter of the blade which ensures a nearly airtight seal on every Arzel’s branch or trunk dampers.
Will my existing Arzel dampers work with the new panel I am installing?
  • If you’re upgrading your Arzel zoning panel, the dampers you have now at your home or business will function the same.
How can I tell if my Arzel damper is open or closed?
  • Simple! A yellow indicator tab is located on the actuator and will be pointing to either open or close. If the actuator is mounted inside the ductwork, the damper blade must be in sight to determine whether it is open or closed.

What parts are used to make an Arzel Zoning System operate? 
  • Arzel’s zoning panels consist of an enclosure that contains a pump, control board, control solenoids and temperature/humidity sensors. Communicating with the thermostats, the control board is able to communicate with your HVAC equipment and open or close the appropriate dampers. The dampers are air-driven and change position by applying pressure or vacuum from the pump.
