open-circuit error charge thermistor (TH1).
24 Serial signal error Compressor stops if outdoor unit
cannot receive serial signal from
indoor unit for 30 seconds.
25 Compressor start- Compressor stops if compressor
up error fails to start up.
26 Compressor rota- Compressor stops if there is no
tion error (at 120° input of position detection signal
energizing) from compressor or input is ab-
normal.
27 Outdoor unit DC Operation stops if there is no in-
fan error put of rotation pulse signal from
outdoor unit fan motor for 30
seconds.
28 PAM overvoltage Compressor stops if DC voltage
error is 400 V or higher.
