Possible causes

(1) Indoor unit LEV actuation failure ĺ Heating (2) BC controller LEV malfunction Heating only or heating main : Indoor LEV 3 (3) BC controller SVM1 and 2 malfunction ->Cooling only (4) BC controller SVA and SVC malfunction ->Cooling only or cooling main (5) BC controller SVB malfunction ->Heating only or heating main (6) Heat source unit LEV7 actuation failure ĺCooling (7) Port address setting error. (8) Refrigerant service valve actuation failure (9) Short cycle on the indoor unit side (10) Clogged filter on the indoor unit (11) Reduced air flow due to dirty fan on the indoor unit fan (12) Dirty heat exchanger of the indoor unit (13) Insufficient heat source water flow (14) Heat source water supply cutoff (15) Dirty or clogged water heat exchanger Items (13) through (15) above reduce the condensing capability of the unit, resulting in high-pressure rise during heating operation. (16) Solenoid valve (SV1a) malfunction The by-pass valve (SV1a) can not control rise in high pressure. (17) Thermistor failure (TH3, TH7) (18) Pressure sensor failure (19) Failure of the thermistor input circuit and pressure sensor input circuit on the controller board (20) Thermistor mounting problem (TH3, TH7) (21) Disconnected male connector on the pressure switch (63H1) or disconnected wire (22) Voltage drop caused by unstable power supply voltage (1) Inner pressure drop due to a leakage. (2) Pressure sensor failure (3) Shorted-circuited pressure sensor outer rubber (4) A pin on the male connect
