Base on outdoor air temp. & comp. top temp., vacuum pump ambient temp. is projected to prevent vacuum pump temp.
rise.
To prevent ice formation in connecting tube during low outdoor air temperature, continuous running protection control is
implemented.
(During low outdoor temp., stagnant water in tube may freeze-up if ON/OFF operation is implemented).
If outdoor temp. sensor abnormal, open or short circuit, temperature reading become below -10°C or above 40°C where
the O
2
supply level will become 0 (operation stop).
Outdoor air temp. update/renew every 30 min during soft dry mode (instant renewal for other mode).
