pressure of the refrigerant fluid
has reached the safety limit.
Transducer BLP, the pressure of
the refrigerant fluid has reached
the minimum value allowed.
There is a refrigerant leak in the
refrigerant circuit.
Transducer BLP, the evaporating
pressure of the refrigerant fluid is
too low.
Probe BT4, the temperature of
the refrigerant fluid has reached
the safety limit.
The internal heat protection of
refrigerant compressor has
triggered.
The circuit breaker QC1 has
triggered.
Probe BT1, the temperature of
body of heat exchanger is under
0°C.

Action
Refer to section "16.2 Specific
malfunctions" on page 114,
"Safety pressure switch HPS has
triggered".
Repair the refrigerant circuit.
Refer to section "16.2 Specific
malfunctions" on page 114,
"Transducer BLP, evaporating
pressure of refrigerant fluid too
low".
