CLIMATE COMPENSATION CURVE
(ONLY WITH EXTERNAL PROBE CONNECTED)
YOU CAN CONNECT AN EXTERNAL TEMPERATURE PROBE
(SEE CHAPTER ‘ELECTRICAL CONNECTIONS’) THAT
AUTOMATICALLY CHANGES THE DELIVERY TEMPERATURE
BASED ON THE EXTERNAL MEASURED TEMPERATURE.
THE NATURE OF THE CORRECTION DEPENDS ON THE
THERMO-ADJUSTMENT VALUE KD SET (SEE CHART).
THE SELECTION OF THE CURVE IS DETERMINED BY
THE MAXIMUM DELIVERY TEMPERATURE TM AND THE
MINIMUM EXTERNAL TEMPERATURE TE TAKING INTO
ACCOUNT THE HOUSE INSULATION DEGREE.
THE VALUES OF THE DELIVERY TEMPERATURES TM, REFER
TO STANDARD SYSTEMS 30-80 °C OR FLOOR SYSTEMS 25-
45 °C. THE SYSTEM TYPE CAN BE SET FROM PARAMETER
P03.
0 - 30
(SET BY DEFAULT AT 15) THE
NUMBERING OF THE VALUE
CORRESPONDS TO ‘KD’ CURVES
ON THE CHART (SEE CHART
BELOW).
