3. Applications
3.1 Heating System with Central Boiler
A large gas, oil or pallet boiler which provides
hot water to several households.
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.
Boiler turned o at night
If the boiler is turned o or has reduced temperature during the night, then make sure that it is
active when the Radiator Thermostat is programmed to warm.
Weather compensation
If the boiler’s heating curve is set to have the
Radiator Thernostats on comfort temperature
constantly, the curve must be increased in or-
der to be able to raise the room temperature
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.
