FAULTS
6 720 803 687 (2012/11)64
U2 (1) Hot gas temperature too high
On the hot gas temperature sensor
TH4, over 125 °C is measured or
over 110 °C is measured for a period
of 5 minutes. In defrost mode, on
TH5 over 40 °C and on the hot gas
temperature sensor TH4 over
110 °C is measured.
Temperature increase in compressor due to
insufficient refrigerant.
▶ Check inlet overheating.
▶ Check for leaks on the refrigerant lines and seal, if
required, then refill the system.
Faulty ball valve (not completely open). ▶ Check if all ball valves are completely open.
Faulty temperature sensor TH4, TH5. ▶ Switch the supply voltage off and on again.
▶ Check if fault code “U3” is shown.
If yes, see “Possible solution / check” for “U3”.
Faulty external unit PCB
Faulty linear expansion valve (LEV). ▶ Check linear expansion valve (LEV).
U2 (2) Insufficient refrigerant
Faulty if hot gas overheating rises in
cooling mode TH4 to TH5 or in
heating mode TH4-TH6 as follows.
All conditions must be met for
10 minutes (at least for 6 minutes
after compressor start).
Conditions 1:
• Compressor is running in heating
mode
• Hot gas overheating is 70 °C or
higher
• TH6 > TH7 - 5K
• TH5 < 35 °C.
Conditions 2:
• Compressor is running
• Hot gas overheating is 80 °C or
higher in cooling mode
• Hot gas overheating is 90 °C or
higher in heating mode
• Condensation temperature
TH6 < -40 °C in cooling mode.
Temperature increase in compressor due to
insufficient refrigerant.
▶ Check inlet overheating.
▶ Check for leaks on the refrigerant lines and seal, if
required, then refill the system.
Faulty ball valve (not completely open). ▶ Check if all ball valves are completely open.
Faulty temperature sensor TH4, TH5.TH6 ▶ Switch the supply voltage off and on again.
▶ Check if fault code “U3” is shown.
If yes, see “Possible solution / check” for “U3”.
Faulty external unit PCB
Faulty linear expansion valve (LEV). ▶ Check linear expansion valve (LEV).
