Display codifica errore controllo sensori
In case error occurs during sensor checking process, error display is as shown below.
Following contents are displayed one after the other on the main PCB of master Unità esterna.
ex) Indoor unit No. 2 Pipe inlet temperature sensor
error
ex) Outdoor Master Unit Liquid pipe temperature
sensor error
ex) IDU No.2 Pipe inlet temperature sensor error and Master
ODU suction temperature sensor, Slave 3 high pressure
sensor error
Caution
1. Up to 5 number of errors is displayed continuously and
repeatedly. In case 5 error occurs, again perform sensor
checking after solving errors.
2. IDU in which error occurred operates air circulation mode.
