Summary description
Control of the THISION S PLUS is
carried out by means on a weather-
compensated, digital heating control
unit for two mixer heating circuits, a
moving average heating circuit, a unit
for the preparation of DHW and an
automatic firing unit for the burner.
Furthermore, a variety of additional
functions are switchable.
The heating control unit uses an
outdoor temperature sensor for
calculating the required target
temperatures for the boiler and the
heating circuits, and it controls the
DHW preparation unit.
Optimal energy savings can be
achieved with the optimization
functions that are switchable.
