1.7 BACnet Object List
Central control (lower central control disable) and forced system stop are only available for 000, 064, 128, and 192.
(Note 1) The room temperature is measured with the suction air. Since the indoor unit fan stops when the thermostat is disabled or the
air conditioner is stopped, or in a special operation such as defrosting, temperature measurement may be affected by the heat
exchanger, and may detect and transmit a different temperature from the actual room temperature. For this reason, this value
should be considered as a reference for the room temperature.
If the building management system manufacturer uses this value for system control (e.g., switching the air-conditioning mode or
preset temperature), the manufacturer must take on the whole responsibility.
(Note 2) The air conditioner saves the settings for the temperature, start / stop status, air-conditioning mode, air direction, and air flow
rate in the nonvolatile memory each time they are changed, so that the settings will not be lost when a power cut occurs. This
nonvolatile memory has a write count limit and may cause a failure if it is written exceeding the limit count.
Therefore when the temperature, start / stop status, air-conditioning mode, air direction, and air flow rate of each indoor unit are
automatically controlled from the central monitoring panel, be sure that the number of changes for each setting should not
exceed 7,000 times per year
