20. DISPLAY OF PARAMETERS
20.1 ADVANCED INFORMATION AND SETTINGS MODE
To enter information and advanced settings mode you must hold down the
IP
button for at least 3 seconds; access to
the mode is indicated by the scrolling letters
“INFO”
.
To exit, just briefly press button
IP
.
To scroll the information press
OK
; when the large figures displayed blink it is possible to modify the value by pressing
the b/-
.
WARNING
Communication between the electronic board of the boiler and the climate controller is not immediate. In some ca-
ses it is possible that you may have to wait a certain time, depending on the type of information transmitted, before
the requested command is carried out.
HEATING CIRCUIT
•
“CH SL”
Maximum setpoint of heating circuit, value may be set using the b/-
.
WARNING
by pressing the button
it is possible to vary the measuring unit scale from °C to °F.
•
“EXT°c”
Outside temperature (with external probe connected).
•
“CH O>”
Heating circuit delivery water temperature.
•
“CH R<”
Heating circuit return water temperature (not contemplated).
•
“CH S^”
Heating circuit water setpoint.
•
“CH MX”
Maximum setpoint of heating circuit (max. settable value).
•
“CH MN”
Minimum setpoint of heating circuit (min. settable value).
DHW CIRCUIT
•
“HW O>”
DHW circuit or storage boiler delivery water temperature.
•
“HW S^”
DHW circuit water setpoint. Value may be set using the b/-
.
•
“HW MX”
Maximum setpoint of DHW circuit (max. settable value).
•
“HW MN”
Minimum setpoint of DHW circuit (min. settable value)
ADVANCED INFORMATION
•
“PWR %”
Power/flame modulation level (in %).
•
“P BAR”
Heating circuit water pressure (in bar).
•
“F L/M”
DHW circuit output water flow rate (in litres/min).
PARAMETER SETTINGS
•
“K REG”
Regulating constant (0.5...9.0) of the heating delivery temperature (factory setting 3 - See section 27 - Graph
3).
Value may be set using the b/-
. A high value gives a higher delivery temperature in the heating circuit. By
setting a correct value of the regulating constant
K REG
, when the external temperature varies the ambient tempera-
ture is maintained at the set value.
•
“BUILD”
Parameter for the size of building to be regulated (1..10 - factory setting 5). Value may be set using the
b/-
. A high value is associated with a building / heating system with a high heat inertia; vice versa a low
value may be associated with small environments or systems with small inertia (thermoconvectors).
•
“YSELF”
Enable/disable the self adapting function of the heating delivery temperature (factory setting 1). The “K
REG” constant is varied to reach ambient Comfort. The value 1 indicates that the function is enabled while 0 indicates
that it is disabled. This function is operative when the external probe is connected.
Press the b/-
to modify this value.
