3.13.4 Interlock control settings on DIDO Controllers (66DC)

DIDO Controllers (PAC-YG66DCA) can control the following items of M-NET devices or the contacts on

DIDO Controllers depending on the change in input contact status.

*DIDO Controller: contact output
*Indoor unit: start/stop control
*Indoor unit: operation mode change
*Indoor unit: temperature setting

The interlock control settings can be made on Maintenance Tools. (Max. 24 patterns)


































Caution:

Before using the interlock control, you must agree to the following.

1. This feature must not be used for disaster prevention or security purposes.

(Not designed to be used in situations that are life-threatening)

2. No functions must be added that allow the malfunctioning unit to run by defeating the

safety features, such as an external ON/OFF switch or a short-circuit.

3. Those settings for the function that are not supported by the interlocked units must not

be made. All the settings must be made within the specified range.
(Failure to observe these precautions may result in malfunctions and failures.)

4. Perform a test run for interlock control, and confirm the correct settings and normal

operation.

5. The system must be configured in the way that integrates the operation of the

interlocked fire and emergency control systems.
