Check point 1. Check connection of connector
•
Check if connector is loose or removed.
•
Check erroneous connection.
•
Check if thermistor cable is open
-> Reset power when reinstalling due to removed connector or incorrect wiring.
↓
Check point 2. Remove connector and check thermistor resistance value
•
For the room thermistor resistance value, refer to
"Thermistor resistance values"
•
If thermistor is either open or shorted, replace it and reset the power.
↓
Check point 3. Check voltage of main PCB
Make sure circuit diagram of each indoor unit and check terminal voltage at thermis-
tor (DC 5.0 V).
NOTE:
For details of thermistor connector, refer to
TECHNICAL DATA AND PARTS LIST on page 02-13.
