11
High voltage locking
fault
Three high voltage alarms occurred within
1 hour or high voltage alarms were not
reset within 10 minutes.
Check whether the condensing fan is running, check whether the condenser
is dirty and clogged, check whether the degree of undercooling is too high,
and manually reset after troubleshooting.
12
Low voltage locking
fault
There are 3 low voltage alarms within 1
hour or low voltage alarms are not reset
within 10 minutes.
Check whether the refrigerant is leaking, check whether the condenser fan
is running normally, and reset manually after troubleshooting.
13
Low voltage sensor
fault lock

troubleshooting
14
Exhaust high
temperature lock
There are three exhaust high temperature
alarms within 1 hour or no reset within 10
minutes.
