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 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.
