Operating Guide
Termix VVX-B – 7 Series BS
6.1.12 HE pressure gauge
The HE pressure gauge indicates the pressure of the HE system.
6.2 DHW temperature control
DHW temperature control
There are various types of DHW temperature control used in
Danfoss substations.
DHW temperature should be adjusted to 45-50 °C, as this provides
optimal utilisation of DH water. At DHW temperatures above 55 °C,
the possibility of lime scale deposits increases significantly.
6.2.1 AVTB controller (20–60 °)
The temperature setting is as follows:
1 = 20 °C
2 = 35 °C
3 = 50 °C
4 = 60 °C
5 = 70 °C
The values are intended as a guide.
The AVTB operates at its best at DH supply temperatures of up to
90 °C.
Thermostatic control
DHW temperature 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.
6.2.2 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.
