Outsidethetimes-of-use,reducedsetpointsareusedforcontrol:thereducedowsetpointis
calculated as the difference between the adjusted values for 'Day set point' (rated room tem-
perature)and'Nightsetpoint'(reducedroomtemperature).The'Max.owtemperature'and
'Min.owtemperature'parametersmarktheupperandlowerlimitsoftheowtemperature.
Aseparategradientcharacteristiccanbeselectedforthelimitationofthereturnowtem-
perature.
Examples for adjusting the characteristic
− Oldbuilding,radiatordesign90/70: Gradient approx. 1.8
− Newbuilding,radiatordesign70/55: Gradient approx. 1.4
− Newbuilding,radiatordesign55/45: Gradient approx. 1.0
− Underoorheatingdependingonar-
rangement:
Gradient smaller than 0.5
Particularly for control operation without room sensor, the room temperatures set for day
('Day set point') and night ('Night set point') only become effective satisfactorily when the
heating characteristic has been adapted to the building/heating surface layout.
