6.0 Controls
6.1 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.
6.1.1 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.
6.1.2 Safety valve
The purpose of the safety valve is to protect the substation from
excessive pressure.
The blow-off pipe from the safety valve must not be closed. The
blow-off pipe outlet should be placed so that it discharges freely
and it is possible to observe any dripping from the safety valve.
It is recommended to check the operation of safety valves at
intervals of 6 months. This is done by turning the valve head in
direction indicated.
