3.4 Heat Pump
A heat pump is generating heating by transferring heat from a relatively low-temperature reser-
voir, such as air or ground, to one at a higher temperature.
Recommendations:
• min. 40 °C supply temperature at the valve.
• su cient heating capacity to increase the room temperature with 1 °C per hour.
• only radiator valves approved for Danfoss adapters.
Weather compensation
If the heat pump's heating curve is set to have
the radiator thermostats on comfort tempera-
ture constantly, the curve must be increased
in order to be able to raise the room tempera-
ture after a setback period.
• If the setback periods are long, further
increase might be necessary.
• If the economy periods are short, less
increase can be su cient.
NOTE: If system is installed during period with outside temperature > 10° C opening point will not be found untill
temperature drops below 7-8° C.0
