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).
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.
