Underfloor temperature controller with remote sensor, flush-mounted, 10-50…°C


Underfloor temperature controller with remote sensor, flush-mounted, 10-50…°C

This electronic two-point controller has been specially developed for controlling electrical or hot water-based heating/additional heating for underfloor and other surface temperature control systems. Remote sensor HF-8/4-K2 (4m) included in delivery. In the event of a sensor failure and short circuit, the heating is switched off. An approx. 5 K lower temperature can be achieved using the temperature reduction input (night-time reduction). Complete device with cover and alre frame.
