E2: Indoor ambient temp. sensor fault (T1 sensor)
Solution:
(1)Check the T1 sensor connection loosen or not, inset it firmly, if not solve, go to next step;
(2)Take out the sensor, measure the resistance of the sensor, it is about 5KΩ at 25 ℃ , if not, replace it; if resistance
normally, change the indoor main board.
