Type	Zone Valve Controls

The Caleffi ZVR104 Z-One is a 4-zone switching relay for zone valves, with 120VAC input, a 24V 40VA output, and priority.

It powers 24V zone valves from the thermostat calls and signals the boiler and system circulator when a zone opens. The priority function lets one zone, typically indirect domestic hot water, take precedence. The control is expandable for additional zones, and the enclosure measures 9.25" high x 11" wide x 3" deep.

Before ordering, confirm your zone valves are 24V and that the total actuator load fits within the 40VA rating. See the installation manual for wiring with and without end switches.
