TROUBLESHOOTING
#1 WAIT TEMPO START Unit is waiting to finish its safety time after a cycle
360 SEC
It is causes by restarting the unit too early, thermostat trigger, and after a unit reset
#2 WAIT Thermostat is OFF or not in demand in either cooling or heating mode
REGULATION OFF
#3 OUTDOOR TOO LOW
Outdoor temperature is too low for the compressor to run in cooling mode : Min tempe-
rature to start 20°C, cut at 18°C ( start 10°C for EC axial version)
TEMPERATURE Outdoor temperature is too low for the compressor to run in heating mode : Min tempe-
#4 PHASE REVERSAL For three phases compressor, phases are not well connected
Reconnect the phase in the right order
#5 SENSOR PHP / ERROR Reconnect the sensor, check the high pressure sensor
#6 SENSOR PBP / ERROR Reconnect the sensor, check the low pressure sensor
#7 SENSOR T1 / ERROR Reconnect the compressor output temperature sensor, check the sensor
Check wire, replace the wire or check the sensor, replace the sensor
#8 SENSOR T2 / ERROR
Reconnect the temperature sensor right on the liquid side of the outdoor heat exchan-
ger , check the sensor
Check wire, replace the wire or check the sensor, replace the sensor
#9 SENSOR T3 / ERROR
Reconnect the temperature sensor right on the liquid side of the indoor heat exchanger ,
check the sensor
Check wire, replace the wire or check the sensor, replace the sensor
#10 SENSOR T4 / ERROR
Reconnect the temperature sensor right on the gas side of the indoor heat exchanger,
return to compressor , check the sensor
Check wire, replace the wire or check the sensor, replace the sensor
#11 SENSOR T5 / ERROR Reconnect the outdoor temperature sensor, check the sensor
Check wire, replace the wire or check the sensor, replace the sensor
