HC71 is a digital and energy efficient clock thermostat for temperature control of electric underfloor heating. The temperature can be controlled by one of 3 options: by an external floor sensor, by the built-in room temperature sensor or in combination. An adaptive control ensures the temperature change according to a setting of your choice. Supplied with a 3 m floor sensor.

HC71 ensures maximum comfort and energy-optimised operation. Despite numerous useful features which provide broad functionality, the thermostat is user-friendly – easy programming is ensured through a clear and easy-to-read menu.

The main display shows: time, weekday, temperature, mode of operation and submenu. The thermostat has a clock function and can be programmed for up to 4 events a day on one of three weekly schedules – individual for each day of the week, Mon–Fri & Sat–Sun, or a 7-days-aweek programme.

In combination with an adaptive function, the thermostat provides individual temperature control according to personal preferences.

HC71 also has  other practical features, such as temperature limitation, open window detection and sensor calibration.
