Did the connector for the
outdoor EVI IN sensor break away from the PCB?
Did the resistance value
significantly stray from the following
temperature table?
Separate the connector of the EVI IN sensor
from the PCB, and measure the resistance value
between the 2 terminals.
Restart operation after changing PCB.
Restart operation after connecting
the connector to PCB.
Change this part as it is the fault of the
