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 IHPT 90 controller (45–65 °)
IHPT is a self-acting flow-compensated temperature controller with
integrated differential pressure controller.
The IHPT operates at its best at DH supply temperatures of up to
100 °C.
By turning the handle for temperature setting in (+) direction
the setting is increased, by turning it in (-) direction the setting is
decreased.

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.
