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 25)
THE NUMBERING OF THE
VALUE CORRESPONDS
TO ‘KD’ CURVES ON
THE CHART (SEE CHART
BELOW).
P17
DISABLEMENT OF DOMESTIC HOT WATER LINE BY MEANS OF SWITCH (ONLY
FOR FAST BOILERS)
BY ENABLING THIS PARAMETER IN THE PRESENCE OF A CONNECTION
(FOR EXAMPLE A BOILER CLOCK OR A TEMPERATURE THERMOSTAT) ON
BOILER CLOCK SWITCH ON THE BOARD, THE REQUEST FOR BURNER
IGNITION ON THE DOMESTIC HOT WATER LINE WILL BE DISABLED UPON
BOILER CLOCK SWITCH CLOSURE.
EXAMPLE 1:
WITH THE BOILER CLOCK SWITCH OPEN, UPON THE REQUEST
FOR DOMESTIC HOT WATER, THE FLOW SWITCH AND THE BOILER WILL
TURN ON.
EXAMPLE 2:
WITH THE BOILER CLOCK SWITCH CLOSE, UPON THE REQUEST
FOR DOMESTIC HOT WATER, THE FLOW SWITCH AND THE BOILER WILL
NOT TURN ON.
