• Use and functioning.
- Start-up display.
Every time power is supplied to the appliance,
the display will activate all symbols for 2
seconds:
While in the next 5 seconds, the display will
indicate the board software version:
After which, the following information
regarding the type of system will be displayed,
the temperature of the solar collector (1 ÷
170°C upper digit) and the temperature of the
storage tank probe (1 ÷ 125°C lower digit):
•
Functioning.
For the description of the parameters, refer to
the table in the previous paragraph.
-
OFF mode.
By pressing the (
) key for 3
seconds, the appliance goes to off mode (also
in the presence of anomalies). In this way, it
is not operational and the display shows off.
Only the anti-freeze protection and the pump
anti-block remain active.
- Solar pump functioning.
The pump activates and deactivates
automatically when it is set in On/Off mode.
Activation:
the solar pump will be activated
by the board if the following conditions occur
at the same time:
T tank < PAR15 – PAR16
and
Solar collector T - tank T > PAR16
D
eactivation:
the board deactivates the solar
pump if one of the following conditions
occurs:
Tank T > PAR 15
or
Solar collector T< tank T + PAR 22
Manual Functioning:
the pump can be set
in On mode (always on) or Off mode (always
off ). In the event of manual setting, the
prevention functions are inhibited.
-
Solar collector cooling function.
This
function is used to manage the pump in
the event of overheating of the solar panel
according to the following table:
Description
Condition
Solar pump
activation
PAR 15 < tank T < PAR 18
+
Solar collector T > PAR 17 - PAR 19
Solar pump
deactivation
Solar collector T (PAR 17 - PAR 19)
-1°C
or
Tank T ≥ PAR 18 +1°C
or
Solar collector T > PAR 17
(reactivates with solar collector T <
PAR17 -1°C)
With parameter 19=0, the solar collector
cooling function is deactivated; the following
conditions remain active:
Solar collector T > PAR17 => Solar pump off
Solar collector T < PAR17– 1°C => Solar
pump on
-
Cold solar collector recognition function.
The board will deactivate the solar pump
(present only with return probe) when:
Solar collector T– solar collector return T <
PAR 21
-
Solar collector anti-freeze function.
The
Solar Pump activates when:
Solar collector T < PAR 23
The board will not deactivate the solar pump
until:
Solar collector T > PAR 23 + 1°C
Important:
the default anti-freeze function
is deactivated PAR 23=0.
-
Solar pump anti-block function.
After 24
hours of inactivity, the system pumps are
activated for 3 seconds.
-
Diverter valve anti-block function.
After 24
hours of inactivity, the diverter valve will be
activated for 5 seconds (in the systems where
the diverter valve is present).
-
Priority solar function.
The function is
active when:
DHW inhibition probe T (PAR 31 - PAR 33)
< DHW set (parallel integration).
DHW inhibition probe T (PAR 31 - PAR 33)
< DHW set (priority integration) and solar
loading pump in off for a time > 5 minutes.
• Anomalies
The following table describes the possible
anomalous conditions that will be displayed on
the basis of the system ration selected.
The possible functioning error conditions are
displayed on the user interface display.
If an anomaly should occur, the (
) symbol
starts to flash as well as the back light (anomaly).
If a no communication anomaly should occur,
the (
) + (
) symbols start to flash as
well as the back light (communication anomaly).
Description of anomaly
Fault code
S1 NTC sensor fault
81
S2 NTC sensor fault
82
S3 T1000 sensor fault
83
Solar pump off
87
- Anomaly 81 NTC sensor fault: the sensor
fault, intended as a short circuit or open circuit
causes the deactivation of the Solar Pump
(active system protection). The protection is
deactivated immediately when this fault is
resolved.
- Anomaly 82 NTC sensor fault: the sensor
fault, intended as a short circuit or open circuit
causes the deactivation of the Solar Pump
(active system protection). The protection is
deactivated immediately when this fault is
resolved.
- Anomaly 83 PT1000 sensor fault: the sensor
fault, intended as a short circuit or open circuit
causes the deactivation of the Solar Pump
(active system protection). The protection is
deactivated immediately when this fault is
resolved.
- Solar pump Off: the solar control unit signals
that the solar pump is in forced Off mode
(parameter 24).
