Don’t let the name fool you: HeatPumPro® does much more than heat pumps. It’s our most popular zone control panel, and it’s compatible with conventional equipment, heat pumps, dual fuel, and multi-stage electric or gas equipment. HeatPumPro is the zoning system you should choose for most residential applications.

HeatPumPro works with any 24-volt system on the market, without any external components. One of the nice things about HeatPumPro is that you can use inexpensive thermostats but still get the features of high-end thermostats because of all of the functionality built into the system.

With multi-stage equipment, HeatPumPro can handle the staging for you. It manages staging with a real time reading in your ductwork and an outdoor sensor. If you need bypass for your multi-stage application, we recommend modulating bypass. There’s a modulating bypass port built into HeatPumPro that allows you to add our ModuPASS® bypass system. We recommend HeatPumPro for multi-stage applications because it has the functionality to get the most out of multi-stage equipment.

Light Commercial Zoning

The AirBoss® is your go-to panel for large homes or light commercial applications. AirBoss can be configured for up to 8 zones, and it can handle multi-stage equipment.

One of AirBoss’s best features is the master zone switch. You can use this switch to run a setback in all zones when the building is unoccupied. The master zone switch reverts all zones to the zone 1 setup. Building occupants can manually flip the switch when they leave, or you can set it on a timer.

AirBoss ships with leaving air temperature protection. You’ll install a sensor in the plenum, then set lockouts for overcooling and overheating. When the temperature reaches those lockouts, AirBoss will stage the equipment back or turn it off and run the fan until the temperature improves. Additionally, AirBoss can handle dual fuel when you add an outdoor thermostat.

When you use AirBoss with multi-stage equipment, you have some options. Either use two-stage thermostats, or have AirBoss manage the staging with the timer on the board. AirBoss also includes a modulating bypass port that allows you to add our ModuPASS bypass system.

New Construction Zoning

Which zoning system should you choose when cost is an important factor? MPS® is our budget-friendly zoning panel for single-stage systems. The MPS panel pairs well with new construction zoning. Installing MPS is a great opportunity to use Arzel’s high-quality dampers without the expense of a more feature-rich panel. Still, you’ll want to consider the age of the equipment. If the owner is planning to purchase multi-stage equipment soon, we would recommend opting for our HeatPumPro panel.

MPS is compatible with single-stage conventional equipment, or heat pump with electric backup. We do not recommend MPS for dual fuel.
