HomeMatic Hm-Cc-Rt-Dn

Flexible through pre-set weekly programs and individual programming directly on the device. Individual adjustment to personal lifestyle habits through freely programmable heating phases (13 switching times for temperature changes per day). A reduction in temperature during ventilation is automatically detected by the integrated window open recognition or via a learnable window contact, preventing unnecessary heating during the ventilation phase. Fits all common radiator valves and is easy to install - without draining heating water or interfering with the heating system. The additional boost function allows for quick, short-term heating of the radiator. Precise temperature setting (to 0.5°C accuracy). Frost protection automation with automated valve opening in case of frost risk. Limescale protection automation: automatic protection against limescale buildup through regular valve movement. Stable fit on the valve thanks to a metal knurled nut. The new room concept allows for easy setup with the CCU2.
