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
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.
