Error codes

Modern air conditioning equipment usually has self-diagnostics systems. Such systems check whether the operation of an air conditioner is normal, and if any errors are detected, informs a user on it. Error messages are displayed in the form of codes on either the internal unit or the remote control of an air conditioner.

Modern air conditioning equipment is usually based on microprocessors. For this reason, control process over air conditioning is automatic, which enables the continuous control over the integrity of the equipment. And if the equipment faces a failure, the entire system stops thus preventing its total breakdown and helping a service technician to determine a faulty component by displaying an error code on the display.
