ABSTRACT:
An apparatus and method for monitoring state information in a trial run mode of a multi-airconditioning system in which a plurality of indoor units are controlled by only one outdoor unit is disclosed. The apparatus and method connects a dedicated controller to the outdoor unit in a trial run mode of the multi-airconditioning system, such that it controls the indoor units and monitors state information of the indoor and outdoor units. The apparatus includes a trial-run-mode controller and a control input & state display unit. The trial-run-mode controller connected to the outdoor unit includes a trial-run-mode program for automatically detecting poor installation of the multi-airconditioning system. The control input & state display unit is connected to the trial-run-mode controller, enters control signals capable of performing control and monitoring operations of the trial run mode executed after the multi-airconditioning system has been installed, and outputs information associated with the control signals.
