Display in solar mode:
- When solar function starts a solar system
icon light up .
- For 10 seconds after the solar pump
activation, are visualized the temperature
collector probe in big digits and the temperature
solar tank probe (sanitary probe) in little digits.
The solar system works when flat-plate solar collector temperature is higher than the
temperature in solar tank in the gauge set in 5 parameter , that defines the temperature
difference keeping between collector and tank. Adjust this parameter how explained in the
chapter 3.2.
If you keep a temperature difference much low, between 5 and 10°C, the circulator starts
up frequently to drain a little heat quantity accumulated in the panels . With a temperature
difference between 10 and 15°C the circulator starts up less frequently because need
more time to create the difference between two devices. During the winter avoid doing
more big temperature difference, when the solar irradiation is limited and sensible
temperature differences could be get to with difficulty. We recommend keeping a
temperature difference between 10-15°C about that is a good arrangement for all year.
Some information :
1) If the temperature in the collector probe exceed 100°C icon“1” lights up to identify a
hundreds in figures, while if the temperature exceed 200°C icon “2” lights up (see
display representation page before).
2) Management of the solar pump: - The minimum collector temperature for the pump
functioning is 20°C. Under this temperature the solar pump doesn’t start .
3) If the tank solar probe detects a temperature higher to the value set in P6 (see
chapter. 3.2 for the regulation mode)(safety temperature tank) the solar pump is
stopped (the heat request panel is stopped).The pump is reactivated when the
temperature of the tank solar probe (sanitary probe) drops below the temperature
set in P6 – 3°C.
4) For 10 seconds after the solar pump activation, are visualized the temperature
collector probe in big digits and the temperature solar tank probe (sanitary probe) in
little digits.
In case of defective probes solar collector and solar tank appears to display an error
message board.
ATTENTION: Always remember to drain properly the boiler discharges, which are the
safety valves and solar sanitary side. Provide a pipe that could bring together a range of
15l/min, to prevent the discharged water overflows and floods the room where the
apparatus is installed. Use fit components to resist 90°C temperature.
