10 TEMPERATURE MANAGER
The control of the heat demands of the individual modules (boiler, hot water tank, heating circuit, solar, etc.)
happens with a so-called temperature manager. To understand the operation of the temperature manager
the scheme which is illustrated in Figure 11.1 is used. It can be seen that a module has inputs and outputs.
The module gives a so-
called temperature demand to his “heat supplier”. This temperature demand is the
sum of an internal calculated temperature demand and an adjustable temperature increase. The heat
supplier must provide this temperature demand to the modules. The heat supplier (heat generator resp.
boiler/buffer), which receives the information (temperature demands) of the modules from the temperature
manager, must provide heat to the individual modules. Thereby the maximum of the temperature demands
(individual modules) is generated by the temperature manager.
Example:
Heat supplier = Boiler
Module 1 & 2 = Heat circuit 1 & 2
Module 3 = Hot water tank
Module 4 = Buffer
Heating circuit 1 Heating circuit 2 Hot water tank Buffer
