Troubleshooting Arzel Zoning Systems

We take pride in manufacturing high-quality products and ensuring our contractors have the support they need. That’s why we’ve put together this comprehensive guide to troubleshooting Arzel Zoning systems. We understand that your time is valuable, and we want to empower you with the knowledge to resolve problems fast, so your customers can get back to enjoying their superior comfort.

Understanding the Basics of Arzel Zoning Systems

A zoning system divides a building into zones, then uses dampers in the ductwork to redirect airflow to the zones that need heating or cooling at any given time. You will see multiple thermostats in a zoned building, and each thermostat controls one of the zones. For more information, see our article: What Is an HVAC Zoning System and How Does it Work?

If you’re new to Arzel Zoning, you probably noticed that our zoning systems work differently than others. Our customers love their reliability. They are not complicated, but the pneumatic tubing will be new to many HVAC contractors. This article on zone control with Arzel explains how our systems work.

Troubleshooting Arzel Zoning Dampers and Pump

Our dampers are powered by a pneumatic pump in the panel box. When dampers aren’t closing appropriately, there could be a leak in the system or a malfunctioning component. It’s time to test the system components to find out where the issue is. Our blog post on diagnosing dampers explains how to test each component. Watch these video demos to understand each part:

• Testing the Arzel Pump (metal enclosure)
• Testing the Arzel Pump (polycarbonate enclosure)
• How to Find the Problem Zone
• How to Test and Diagnose Dampers
• How to Test and Diagnose Solenoids

When you have some extra time, watch our webinar on damper, solenoid, and pump testing to get a good foundation on how Arzel Zoning troubleshooting works.

Troubleshooting Arzel Zoning Control Panels

If you need to troubleshoot the zoning panel on an Arzel Zoning system, we have a variety of resources available. Some of them relate to all of our panels, and others are specific to one panel.

Here’s a list of our best resources for troubleshooting specific issues:

• Low-Voltage Troubleshooting in the HVAC Industry (video demo)
• Low-Voltage Troubleshooting: How to Find the Problem (article)
• Fixing Thermostat Problems with Arzel Panels (video demo)
• Understanding Static Pressure (article)

When you have some extra time, watch our webinar on setup and troubleshooting for HeatPumPro, MPS, and AirBoss.

How to Use the HeatPumPro’s Screen

The HeatPumPro’s main screen tells you what the panel is doing at the moment you look at it. To understand what everything means, watch this video: Settings on the HeatPumPro’s Main Screen. In the process of troubleshooting, you will probably need to move to the other screens. To understand how to navigate the screens and what they show, see our video demo: Using the HeatPumPro Screens.
