*1: When the operation mode is set to “AUTO (single set point)” on the remote controller, this setting will be used as the set
temperature for the AUTO mode on BAC-HD150.
When the operation mode is set to “AUTO (dual set points)” on the remote controller, [Set Temp Cool (AV_xxxx24)] and
[Set Temp Heat (AV_xxxx25)] will be used as the set temperatures for the AUTO mode on BAC-HD150.

(1) Monitoring and setting temperatures from BMS
When setting the temperature settings for single set point indoor unit groups from BMS, use [Set Temp (AV_xxxx10)]. If BMS
uses the dual set point objects to send commands to single set point indoor unit groups, BAC-HD150 will send an error to
BMS.
Use [Set Temp (AV_xxxx10)] and [Set TempCool (AV_xxxx24)]-[Set Low Limit SetbackTemp (AV_xxxx28)] temperature setting
objects for dual set point indoor unit groups.
(2) When the BMS supports only the single set point function
Enable “Old Model Compatibility Mode” of the BAC-HD150 Setting Tool. BAC-HD150 will start up in the single set point mode.
Refer to section 8.2 “System Settings” in BAC-HD150 Setting Tool Instruction Book for details.
