Things to pay attention to
NTC ERROR
If a red LED is permanently lit on the right side near the sensor connector, the NTC sensors are not functioning correctly.
They may not be connected at all, or one of them may be broken or otherwise faulty. In this state, the unit cannot operate in AUTO mode.
Solution:
Check the wiring, connector seating, or replace the sensors. If you have an ohmmeter, you can easily verify their functionality.

BATTERY LOW
The CR2032 battery that maintains the date and time is nearly depleted. It is time to replace it. This will only be needed once every several years.
Solution:
Open the enclosure and gently push the metal clip holding the battery to the right to release it. Insert the new battery under the clip first, then press it gently to the right on the opposite side of the plastic holder so it snaps into place.
