Environmental Requirements - OSCAR OS10 Mode D'emploi

Part of the reason for not working:
●The solar air heater don't raise the temperature or ventilate in these situations:
The power displays abnormal, LCD screen does not turn bright, all the value displays 0, sometimes it
shows only 4V, flickers, the voltage is insufficient.
Solution:
1.The day is sunny, however the angle of sunlight is wrong. Maybe the sun is directly above or tilted
too much.
2. Check if the pv panel is shaded by the trees or buildings etc. Make the whole pv panel is exposed in
the sunlight. Any shadows on the pv panel might impact the generation of power. If it's overcast, the
sun isn't shining or is only shining weakly, during the night, early in the morning or late at night and
when the panel is covered by snow or ice or during rain.
3. Pull the wires out and try to plug it back in the thermostat. Maybe it's a hit.
4.The correct clock must be set for the collector to work normally. Just for LCD thermostat.
5.The temperature and humidity display, or the operation of the fan and automatic air vent will have
some lag. Within 10-30 minutes, the work will start when stable light is detected. It is recommended
to check again after half an hour. Just for LCD thermostat.
If the problem is still not resolved, please open the silver tape. It is possible that a connection cable
has been disconnected; It could be a wire collision. Please use an electric tape to connect it back. If you
need to replace the fan, please open the fan cover. The rear panel is attached with screws that can be
removed. After repairing, just screw the two symmetrical screws back.
Please take photos for us to find the solution. As long as the photovoltaic panel is good, it can be
repaired. If you can do a few tests that will help us determine what is wrong with that solar air heater
it would be very helpful.
