CLIMATE COMPENSATION CURVE
(ONLY WITH EXTERNAL PROBE CONNECTED)
YOU CAN CONNECT AN EXTERNAL TEMPERATURE PROBE (SEE
1.1.16 ‘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 86-167 °F (30-75 °C) OR FLOOR SYSTEMS
77-113 °F (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).
P17
SETS THE TEMPERATURE MEASUREMENT UNIT
THROUGH THIS PARAMETER YOU CAN SET THE TEMPERATURE
MEASUREMENT UNIT DISPLAYED: CELSIUS (°C) OR FAHRENHEIT
(°F) DEGREES.

ENABLING BUS INDUSTRIAL PILOTING 0 -10V
THROUGH THIS PARAMETER YOU CAN ENABLE OR DISABLE THE
BUS INDUSTRIAL INPUT 0-10 V TO SET THROUGH EXTERNAL BUS
THE BURNER POWER OR THE DELIVERY TEMPERATURE.
