Watts Electrothermic Manifold Actuator
Description
The Watts Underfloor Heating Electrothermic Manifold Actuator is an automatic thermal actuator designed to regulate water flow on individual zones or rooms of underfloor heating systems. Installed directly onto the manifold valves, these actuators open or close the water flow in response to signals from individual thermostats, allowing precise temperature control and efficient system operation.
Using electrothermic actuators instead of pure thermostatic versions enables remote control capabilities, making them ideal for modern smart heating systems requiring individual zone management.
