7. Description of the controller functions
The TROVIS 5432 Heating and District Heating Controller is designed to control the flow tem-
perature in heating systems. The control is either weather-compensated using an outdoor or
flow sensor, or based on a fixed set point for the flow temperature just using one flow sen-
sor. The flow temperature is controlled so that the required room temperature is achieved.
When used as a district heating controller, the controller can limit the return flow tempera-
ture.
The connected sensors allow the controller to measure the respective temperatures which are
transmitted to the central signal processing system.
Subsequently, the system issues a control signal corresponding to the preset set points to
operate the control valve and a binary signal for the heating circulation pump.
If a sensor for the drinking water temperature TS is connected, the drinking water priority is
automatically activated.
