SChEMATIC DIAGrAM
The heating (high temperature or floor heating) is controlled by the AF200
outside temperature detector supplied with the Control Unit and by the RFF
room detector or RS Zone Unit.
The detectors are connected to a controller that can be built into the boiler.
This controller operates the four-way valve and the circulator depending on
requirements (calculated from the outside temperature) and on the start
temperature measured by a third detector.
- The system provides a high level of comfort as the start temperature is
constantly adapted to heating requirements.
- Built-in timer with setting of heating times (day) and lower temperature
times (night).
- The room detector allows the user to adjust the comfort setpoint to their
specific requirements.
