Description

DeepL Translate

The four JUNG room thermostats in the JUNG design offer heating or cooling mode, ECO mode and open window detection based on temperature. They also have an LED display. They are operated using two-point control or pulse width modulation.

When users have a long press on the rotary knob, the heating system switches to frost-protection mode. To set the comfort temperature, rotating the control unit is sufficient. The thermostats are therefore suited both to heating and cooling. For this, three of the models have internal temperature sensors. Furthermore, two thermostats have a temperature drop detection and turn down the heating if, for example, a window is opened. The FTR 231 model has an external temperature measurement that registers the temperature combined with electrical underfloor heating, and an Eco mode (night setback). With the exception of the RTR 230 model, the thermostats can either be operated using two-point control or pulse width modulation.
