Radiant Heat Controls
Radiant Heat Controls include actuators, thermostats, and zone valves. These radiant heat controls will operate the flow of water in a radiant heat system.
Actuators
We offer a motorized valve actuator, which features a quick-opening motorized va…lve head, as well as a slow-opening thermal actuator. These actuators mount directly onto 1-1/4" Brass and TruFLOW Valved Manifolds, and provide individual flow control on a multi-zoned manifold (manifold serving more than one zone).

Thermostats & Controls
Here you can find Wirsbo radiant heat thermostats, which offer differential and …pulse-width modulation and digital filtering, Wirsbo setpoint controllers to be used as air temperature thermostats or floor temperature thermostats, proMIX radiant heat controls, Wirsbo Cat5 wiring controls designed for simplicity of installation, and several Wirsbo fully assembled panels.

Relays & Zone Valves
Pump switching relays control the operation of a single circulator or pump from …a 24-volt signal. Relays include secondary low-voltage terminals for boiler operation. Radiant heat zone valves feature 3/4- and 1-inch sweat connections, and provide flow control for a single-zoned radiant heat manifold (manifold serving one zone). This category also contains zone control modules, which are printed circuit control and diagnostic devices designed for use with Wirsbo thermostats, motorized valve actuators (MVAs), thermal actuators or zone valves.

Mixing Valves
We feature Wirsbo tempering valves and motorized mixing valves. Wirsbo 1" three-…way tempering valves are ideal for radiant heat systems and thermostatically controls water temperature ranges between 80 and 160°F, while Wirsbo three-way floating action valves feature floating action motor operation, and are used with the proMIX 101 or SYSTEMpro 311. We also feature the radiant mixing block - a complete injection mixing system, combining a variable speed injection mixing control, injection circulator, system circulator and air elimination all in a single convenient unit.

Uponor Differential Pressure By-Pass Valves
The self-acting, automatic Differential Pressure By-Pass Valve maintains flow ra…tes (e.g., through a low water content gas boiler), or controls the differential pressure in a hydronic heating system. Valves come with NPT unions.
