Introduction The ATAG Brain timer thermostat is an advanced digital timer thermostat, in which the most recent computer technology has been incorporated. The ATAG Brain has been specially developed for use with the ATAG S-HR heating appliance. The heating appliance passes on a number of unique features to the ATAG Brain timer thermostat. The ATAG Brain is unique in that in contrast to a standard timer thermostat it has fewer switch-on moments.
Your heating and hot water supply (if present) are controlled according to time settings (timer program). Timer program 1 is always active from the factory. It is then possible to select 2 other timer programs. The times and temperatures can be changed within the timer program. A number of factory settings are, for example: Day temperature: 21°C Night temperature: 15°C Timer program 1: 07.00 - 10.00 hours 19°C 10.00 - 17.00 hours 19°C 17.00 - 23.
