| 13-2-13 | The floor, tenant, area, or air conditioner is not displayed in the proper order. | The floor, tenant, and area are displayed in the order of the floor number, tenant number, and area number set in the setting file. Change the display order as needed. The air conditioners are displayed in the order of outdoor system number and indoor units number set in the air conditioner. Change the display order as needed.

| 13-2-15 | The value of air temperature is incorrect. | The air temperature displays the intake temperature corrected for the room temperature control of the air conditioner. The displayed and actual temperatures differ because correction amount varies depending on an operation mode (cooling or heating). |
| 13-3-1 | The date or time change is not applied. | The internal processing of the controller may be given priority over a setting operation from the browser. Try to change the date or time again. |
| 13-3-2 | The air conditioners do not operate as scheduled. | 1. Turn on the controller. 2. Check that the operating schedule of each air conditioner is correctly set. Check that the air conditioner for which the operating schedule is set matches the air conditioner to be operated. Check that the date and time setting is correct. Correct the settings above if necessary, and set operating schedule so that the air conditioner operates after 3 minutes and see if it operates as scheduled. 3. Turn off the controller, then turn it on again after 30 seconds. |
| 13-3-3 | The operation is unavailable with the remote controller. | Check with the controller LCD that the control is set to "CENTRAL". To enable the operation with the remote controller, change the setting in the controller to "No indication". |
| 13-3-4 | The air conditioner does not operate according to the operation setting, such as operate or stop, made from the browser. The settings go back to the previous state after a while. | 1. Check if the communication error with the air conditioner is detected. 2. Change the setting in the setting file so that air conditioner is set as the main unit. 3. If the setting falls outside the set temperature range, the temperature will be set to the upper or lower limit value of the set temperature range. If the setting falls outside the range of the set operation mode, the air conditioner does not operate in the mode set. It operates in the mode before the change. |
