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 Circulator pump UPM3
UPM3 Pumps can be controlled in constant pressure, proportional
pressure or constant speed mode defined by the means of a smart
user interface.
The variable speed modulating modes allow the pump to match its
performance to the system requirements, helping to reduce noise
when thermostatic valves are closing down.
