- DIDO Controllers and AI Controllers have an interlock control function.
DIDO Controllers can also change the operation status of M-NET devices (such as indoor units, DIDO
Controllers) by sending operation commands. DIDO Controllers can output contacts on DIDO Controllers
themselves depending on the change in input contact status.
AI Controllers can change the operation status of M-NET devices (such as indoor units, DIDO
Controllers) by sending operation commands depending on the change in measurement values.
"Interlock operation conditions" for the "interlock control function" can be set on Maintenance
Tools.

Before using the interlock control function, plan carefully how the air-conditioners will be used. If
the interlock control function is used without thorough consideration, unexpected operation may
result.
