しかし、室外ユニットに設けた試運転操作手段により室内機および室外機を試運転すると、試運転前の室内機および室外機の運転状態に関する情報は室内機操作リモコンの指令値としてのみ残っているので、室外機側の点検が終了した後で空気調和機を復帰するためには室内機が設置されている各部屋に移動しなければならない。そのために作業員の動線が長く、点検時間がその分余分に掛かるという問題がある。
また、室内機操作リモコンを操作して空気調和機を試運転前の運転状態に復帰させるとき、室内機操作リモコンの操作ミスの可能性があるという問題がある。 However, if the indoor unit and the outdoor unit are trial run by the trial run operation means provided in the outdoor unit, the information about the operation state of the indoor unit and the outdoor unit before the trial run remains only as a command value of the indoor unit operation remote controller. In order to return the air conditioner after the side inspection is completed, it is necessary to move to each room where the indoor unit is installed. For this reason, there is a problem that the flow line of the worker is long and the inspection time is increased accordingly.
Further, when the air conditioner is returned to the operating state before the trial operation by operating the indoor unit operation remote controller, there is a problem that there is a possibility of an operation error of the indoor unit operation remote controller.

この発明の目的は、試運転しながら点検を行った室外機側から試運転前の運転状態に復帰することができる空気調和機の室外機を提供することである。   The objective of this invention is providing the outdoor unit of the air conditioner which can return to the driving | running state before test operation from the outdoor unit side which checked while performing test operation.

上記室外制御基板に設けられたコネクタと接続することにより上記室内機と通信することができる保守用基板を備え、上記保守用基板は、上記リモコンからの指令により運転しているときの空気調和機の運転状態を上記室内機から取得して記憶する状態取得手段と、上記記憶された運転状態で運転を復帰するように上記室内機に指令する復帰指令手段と、を有する。 An outdoor unit of an air conditioner according to the present invention is capable of communicating with an indoor unit whose operation is controlled from its own side by a remote controller, and includes a test operation operation unit that executes and stops a test operation regardless of the control of the remote controller. In an outdoor unit of an air conditioner including an outdoor control board that performs
A maintenance board capable of communicating with the indoor unit by connecting to a connector provided on the outdoor control board, and the maintenance board is operated by a command from the remote controller. State acquisition means for acquiring and storing the operation state from the indoor unit, and return instruction means for instructing the indoor unit to return to operation in the stored operation state.

この発明に係る空気調和機の室外機の効果は、室外制御基板につながるコネクタが実装され、保守用基板に実装されたコネクタにより接続することにより保守用基板を用いて室内機の運転状態を取得し記憶できるとともに点検が完了した後で記憶された室内機の運転状態の情報を用いて運転を復帰することができるので、リモコンを用いなくても室内機の運転を復帰でき、作業員が再度室内に戻る動作が必要なくなり点検時間が短縮することができることである。   The effect of the outdoor unit of the air conditioner according to the present invention is that the connector connected to the outdoor control board is mounted, and the operation state of the indoor unit is acquired using the maintenance board by connecting with the connector mounted on the maintenance board. Since it can be stored and the operation can be restored using the stored information on the indoor unit operation state after the inspection is completed, the operation of the indoor unit can be restored without using the remote control, The operation to return to the room is not necessary, and the inspection time can be shortened.
