Simple to use, the HTR-RF(20) is perfect for users who appreciate a traditional dial face and want minimal intervention in the heating system. With silent switching and TPI (Time Proportional & Integral) calibration, accuracy and efficiency are nevertheless assured.

The addition of wireless technology means that installation is also extremely quick and trouble-free without the need for additional wire runs. The wireless interface also allows the HTR20RF to connect to a SALUS universal connection gateway, through which it can be controlled remotely from anywhere via a simple app from a smartphone, tablet or PC.
