Product description

OS10/OS20/OS30:   

Heating outdoor fresh air: available in spring, autumn and winter.

OS22/OS32/OS42:  2-in-1 function

Heating outdoor fresh air: suitable for all models.

Heating indoor air circularly mold: can keep heating the room air and increasing the room temperature, and can keep away from any wet or cold or smog air. This mode is the best way to heat the room. Applicable to OS22/32/42.

When the outdoor temperature is too low, just open the air inlet indoor to keep heating the indoor air. Just close the air inlet indoor to introduce and heat the fresh air outdoor.

The price includes a mechanical thermostat and all necessary mounting accessories. Extra cost will be charged if customer needs LCD thermostat and automatic air outlet.
Reducing the air volume can increase the air temperature into the room. Increasing the air volume can increase the heating efficiency and dehumidification effect.

When used in basement and other high humidity environment. It is recommended to buy a larger model, which have stronger capacity for dehumidification, deodorization, removal of formaldehyde and hydrazine.

 

 The special felt cover can be spliced with aluminum alloy collector (OS20/22/30/32) and installed on a flat roof or wall. The air through the black felt gap (air intake volume remains unchanged) can efficiently absorb the heat of the sun, thereby increasing the temperature of the outdoor fresh air entering the room. As long as the felt cover is spliced, the temperature of the fresh air entering the room can be increased: F7----about 10℃; F11----about 15℃. 

After a long period of outdoor dust and rain test, the air intake volume is reduced by up to 3%. It can effectively filter Dust and become clean after rain washing, no maintenance is required. The service life is more than 5 years.

Mechanical thermostat

The standard configuration can only work in the sun, and cannot be connected to electricity. Ventilator will stop working when the room temperature reaches the set value (eg. 25℃).

New LCD thermostat: Ventilation and dehumidification or humidification are available even on cloudy or summer nights. Smart curved touch screen: the perfect combination of art and technology!  

Ventilation, heating, dehumidification or humidification.

Solar collector with LCD thermostat, provides you with a healthy climate and automatically processes indoor air. Simple operation, thoughtful air management expert! There are five modes: automatic, humidity control, manual, heating and ventilation, continuous heating of indoor air. Can detect indoor and outdoor temperature and humidity, moisture content in the air. Automatically switch between solar and electrical energy. Ventilate regularly to purify the air every day. As long as the collector does not work, the air vents automatically close, completely isolating the outdoor cold air.

The correct clock must be set for the collector to work normally. To set the clock, press the SET and M buttons at the same time for more than 2 seconds.
