The i-Link series Zone Valve Controls simplify the field wiring and yet control up to six zone valves in a multi-zone hydronic heating system. The contractor friendly Printed Circuit Board eliminates the problem caused by incorrect wiring and saves hours of installation time. There would be no more “messy” look of conventional zone valve installations.
Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers. Field selectable priority with Priority Protection Timer ensures other zones get heat every one hour and prevents freeze-ups in the event of a priority zone failure. The End Switch delay timer let the two wire type zone valves fully opened before turning on the circulator. The panel provides EZ screwless terminal blocks for connections to the thermostats and zone valves. In addition, LED indicators on the front panel provide functional status and easy troubleshooting.
