Schedule of dependence of pressure on the amount of solar energy

Solar gauge

Location:

Central part of the front panel.

Function:

Due to the photo diode, it transforms sun rays penetrating into the interior through windshields, into the electric current which is supplied into the controller.

Way of checking.

If the display lamp of check of the solar gauge lights up - A, they perform checking following the below-mentioned points.

• Before removal of the gauge, they cover and protect the gauge on the front panel.
• Remove and place the gauge - B under direct sun rays, and they measure pressure between the ends of outlets (measured pressure of the gauge approximately 1,4±0,2V).

When the measured pressure corresponds to the specified value, on the automatic temperature regulator they check presence of breakage and short circuit between wires of gauges.
