Enhance the performance of underfloor heating systems with the TUS 230v 2 Wire Actuator, a high-efficiency thermal actuator engineered to control individual manifold ports and allow zoning of your underfloor heating system.
Designed to work seamlessly with the TUS wiring centre and room thermostats, this actuator enables room-specific temperature management – delivering greater comfort, more efficient energy use, and consistent heating performance.
Supplied in a ‘normally closed’ configuration, when the corresponding connected thermostat calls for heat, the actuator engages to open the valve and allow water flow into the loop to feed the corresponding zone.
With quiet operation and a modern, compact build, it’s ideal for residential or commercial installations alike.
Installation should be done by hand to avoid damage to the actuator. Each actuator comes with a red clip, which needs to be removed for the actuator to operate a normally closed (NC) operation.
