Installed with the 4 Zone Valve Controller™, MacDuffco’s 24 VAC Relay™ can intelligently activate radiant heat system circulating pumps or mixing valves when any thermostat circuit is calling for heat. This saves wear and tear on circulating pumps – and increases system efficiency – as the pumps only operate when heat is required.

Specifications:

  • Connects directly into either a 4” octagon or 4” square electrical box with ½” knockouts.
