Operating Guide Termix Compact 28 VMTD-FI

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 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.
6.2.2 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.
