Azel SZ-86DX 6 zone Valve Control With Priority for Hydronic and Radiant Heating

Manufacturer Part Number: SZ-86DX

The Azel SZ-86DX Zone Valve Controls streamline field wiring and efficiently manage up to six zone valves in a multi-zone hydronic heating system. The user-friendly Printed Circuit Board (PCB) eliminates issues associated with incorrect wiring, significantly reducing installation time and avoiding the clutter typical of conventional zone valve setups.

The Intelligent Linking System (i-Link) supports unlimited zone expansion by integrating additional i-Link controllers. It features a field-selectable priority with a Priority Protection Timer that ensures all zones receive heat every hour, preventing freeze-ups in case of priority zone failure. An End Switch delay timer allows two-wire zone valves to fully open before activating the circulator. The panel includes EZ screwless terminal blocks for straightforward connections to thermostats and zone valves. Additionally, LED indicators on the front panel provide clear functional status updates and facilitate easy troubleshooting.
