Azel SZ-V4 4 Zone Valve Control for Hydronic Radiant Floor Heating Systems

Manufacturer Part Number: SZ-V4

The Azel SZ-V4 Zone Valve Controls for hydronic radiant floor heating systems simplify field wiring while effectively managing up to four zone valves in a multi-zone setup. The user-friendly Printed Circuit Board (PCB) eliminates issues caused by incorrect wiring, saving significant installation time and avoiding the clutter typically associated with conventional zone valve installations.

The Intelligent Linking System (i-Link) enables 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 a priority zone failure. The End Switch delay timer allows two-wire zone valves to fully open before activating the circulator. The panel includes EZ screwless terminal blocks for effortless connections to thermostats and zone valves. Additionally, LED indicators on the front panel provide functional status updates and facilitate easy troubleshooting.
