FHT

The radio heating system FHT is ideally suited to save energy through intelligent control of the heating valves and to create a comfortable indoor climate at different times.

Warning

Only FHT8b/FHT80b can be connected to the FHZ1000PC Professional, FHZ1300PC or FHZ1300PC WLAN. The much cheaper FHT8R are only suitable for single-mode and can not be connected to the FHZ.
