6.0 Controls

6.1 Heating circuit

6.1.1 Differential pressure controller
The differential pressure controller smooths out the fluctuations in
pressure arriving from the district heating network. The operating
pressure in the substation is thus held steady.
6.1.2 HE temperature control
The HE flow temperature in the heating circuit is controlled by the
HE temperature controller.
6.1.3 RAVK controller
RAVK controller (25-65 °C). The temperature setting is as follows:
1 = 25 °C
2 = 35 °C
3 = 45 °C
4 = 55 °C
5 = 65 °C
The values are intended as a guide.
Thermostatic control
The temperature of the HE flow line is adjusted as follows:
To increase temperature, turn the handle on the thermostatic
controller to select a higher number.
To decrease temperature, turn the handle on the thermostatic
controller to select a lower number.
