How to fix Toshiba BMS-CT1280TU LCD not displaying?
If the LCD on your Toshiba Controller does not display, check that the power is not turned off by the breaker or similar issue. Look for the green LED at the lower rear of the main unit and on the AC adapter to confirm power is being supplied. Also, ensure that the wiring of the power outlet and AC adapter is properly connected, again checking for the green LEDs as indicators of power.
Why schedule setting changes have not been reflected on Toshiba BMS-CT1280TU?
If the schedule setting changes have not been reflected on your Toshiba Controller, make sure you are only making changes from either the main unit or the Remote Control Software, not both.
What to do if Toshiba BMS-CT1280TU schedule does not work?
If your Toshiba Controller schedule is not working, check your Scheduler Operation settings. Try operating another air conditioner to verify if the actual air conditioner responds. Note that if a day is set in both the Weekly schedule and a Special day schedule, the Special day schedule will take precedence for that day.
What to do if I cannot log in to Toshiba Remote Control Software?
If you cannot log in to the Toshiba Remote Control Software, remember that each user can only log in from one PC at a time. Also, select a display style other than classic style by going to [Start] - [Control Panel] - [Appearance and Personalization] - [Change the theme]. The supported operating systems of this software are Windows 10 and Windows 11.
How to turn off Toshiba BMS-CT1280TU?
To turn off the power on your Toshiba Controller, select [Menu]-[Functions]-[shut down].
Why Toshiba air conditioner doesn't cool or heat?
If your Toshiba air conditioner isn't cooling or heating, it might be due to demand control or power saving settings, which reduce the outdoor unit's capacity to lower power consumption, potentially increasing the time to reach the set temperature. Additionally, forced thermo OFF stops the outdoor unit's operation, causing the indoor unit to function only as a fan.
How to fix Toshiba Remote Control Software not starting?
If the Toshiba Remote Control Software won't start, download and install .Net Framework 4.8 from the software's download website. Ensure that your PC and the LAN of the Unit are connected properly by checking the LAN cable and network settings. The IP address to enter during installation should be the IP address of the controller main unit, not the PC's IP address. Also, confirm that your operating system is Windows 10 or Windows 11, as other OS versions may not be supported.
Why do air conditioner settings change arbitrarily on my Toshiba BMS-CT1280TU Controller?
If the air conditioner settings change arbitrarily on your Toshiba Controller, note that stopping the air conditioner with the local remote control or its schedule will override any settings made by the Controller. Similarly, stopping the air conditioner with the PC app "Remote Control Software" also overrides previous settings. Also, the air conditioner may stop automatically if an external input signal is received via the external interlocking function.
Why is the webpage of my Toshiba Controller not displayed?
If the Toshiba Controller webpage is not displaying, first ensure the System Controller is powered on. You cannot connect to the webpage if it is off. Also, verify that your PC and the Controller's LAN are properly connected, checking both the LAN cable and network settings. If a proxy server is in use, exclude the IP address of the System Controller. Note that you cannot connect to the Unit unless the IP address of the PC is set.
