Set Temp Auto
AV_xxxx26
°F/°C
• Make a setting of set room temperature in auto mode of
the specific group from BMS.
After doing so, check that the set room temperature in
auto mode of the group renews the temperature using
system controller or remote controller.
• Change the set room temperature in auto mode of the
specific group using system controller or remote
controller.
After doing so, check that the set room temperature in
auto mode of the group renews the temperature on BMS.
Set High Limit
Setback Temp
AV_xxxx27
°F/°C
• Make a setting of set upper limit temperature in setback
mode of the specific group from BMS.
After doing so, check that the set upper limit temperature
in setback mode of the group renews the temperature
using system controller or remote controller.
• Change the set upper limit temperature in setback mode
of the specific group using system controller or remote
controller.
After doing so, check that the set upper limit temperature
in setback mode of the group renews the temperature on
BMS.
Set Low Limit
Setback Temp
AV_xxxx28
°F/°C
• Make a setting of set lower limit temperature in setback
mode of the specific group from BMS.
After doing so, check that the set lower limit temperature
in setback mode of the group renews the temperature
using system controller or remote controller.
• Change the set lower limit temperature in setback mode of
the specific group using system controller or remote
controller.
After doing so, check that the set lower limit temperature
in setback mode of the group renews the temperature on
BMS.

INACTIVE : Normal
ACTIVE : Error
• Disconnect the cable that is connected to the BAC-HD150 (LAN
2 port). Confirm that the Expansion Controller communication
status changes to “Error (ACTIVE)” on the BMS.
