Pump Relays control circulator or pumps from a 24-volt signal.

Wirsbo Thermal Actuator - 4 wire (24VAC). Slow opening thermal actuator, with end switch, mounts directly on 1-1/4" valved brass and TruFLOW manifolds.

The MVA provides individual flow control on a multi-zoned manifold (manifold serving more than one zone).

The module is a printed circuit control and diagnostic device designed for use with Wirsbo Thermostats, Motorized Valve Actuators (MVAs), Thermal Actuators or Zone Valves.

The Wirsbo Snow Melt Enable Kit enables the user to remotely start and stop the snow and ice melting system, as well as the ability to adjust the running time of the snow melting system.

Optional Part

Intelligence. Versatility. Style. The Wirsbo pro Series SetPoints.

50 VA Transformer (24 VAC) comes with a 4"x4" metal mounting plate.

Wirsbo Four Wire Zone Valves provide flow control for a single-zoned manifold (manifold serving one zone), and has a built-in flow balancing feature.

Use with Wirsbo 5/16" hePEX only.

Designed for the TruFLOW™ Manifold System, the Wirsbo FlowMaster™ uses superior technology to measure flow and temperature in hydronic radiant floor heating systems.

Non-corrosive reactive valve, 1" nominal sweat union connections

Replacement Part

TruFLOW Loop Thermometer comes with an R20 (QS-style) female union on one end and an R20 (QS-style) male on the other. Thermometer well and removable thermometer are included.
