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 Flow controller with integrated control valve
The controller is a self-acting flow controller with integrated control
valve. The controller closes when set max. flow is exceeded and
can be used in combination with Danfoss electrical actuators with
or with out safety function. Spring return motor can be used as
safety function by power failure.
6.1.4 Electric 2–way motorized valve
Actuators with or without safety function are available for 3-point
controls. Spring-return actuators can be used to provide safety
shut-off in the event of power failure.
