This is an archive article published 10/09/2009. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

The radiator valve is actuated via a battery powered motor. In operating mode, the Rondostat alternates between a comfort temperature and an economy temperature according to an adjustable timer program with 28 set points per week (4 individual set points per day). The factory preset of the timer program is:
6:00 – 22:00 h = 21°C and 22:00 to 6:00 h = 16°C.
The set points for comfort and economy temperature as well as the time periods are freely adjustable. A handwheel allows a manual temperature adjustment.
