Thermal actuator for underfloor heating manifold – normally closed NC
Actuators can be used e.g. with thermostatic valves in the manifold for underfloor heating or with zone valves. They allow cutting off the heating medium supply to a given element. They can cooperate directly with room thermostats or via wiring centres (wired or wireless). NC actuators are normally closed devices, which means that when there is no current, the actuator closes the loop. The condition of the actuator can be checked quickly thanks to the indicating element.
Product advantages:
• faster installation thanks to the ‘FIRST OPEN’ function
• short opening time – approx. 2 min
• has a stroke of about 4 mm
• small size
• consumes a small amount of power
