thermistor.
Malfunction
Decision
Conditions
When the discharge air temperature thermistor becomes disconnected or shorted while the unit
is running.
Supposed
Causes
! Defect of indoor unit thermistor for air outlet
! Defect of indoor unit PC board
Troubleshooting
∗ Refer to thermistor resistance / temperature characteristics table on P192.
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
Replace the indoor unit PC board.
Connect the thermistor and turn
on again.
NO
NO

- Characteristics of new refrigerant r410a 1 performance almost the same performance as r22 and r407c 2 pressure working pressure is approx 1 times more than r22 and r407c 3 refrigerant composition few problems in composition control since it is a quasi azeotropic mixture refrigerant 205
- H 1 non azeotropic mixture refrigerant mixture of two or more refrigerants having different boiling points h 2 quasi azeotropic mixture refrigerant mixture of two or more refrigerants having similar boiling points h 3 the design pressure is different at each product please refer to the installation manual for each product reference 1 mpa 10 9716 kgf c 205

- R410a is used under higher working pressure compared to previous refrigerants r22 r407c furthermore the refrigerating machine oil has been changed from suniso oil to ether oil and if oil mixing is occurred sludge results in the refrigerants and causes other problems therefore gauge manifolds and charge hoses that are used with a previous refrigerant r22 r407c can not be used for products that use new refrigerants be sure to use dedicated tools and devices 207
