(Building Management System controlled across to Modbus RTU Master device) and it
can be managed from the BMS, the Remote Controller or the MH-RC-MBS-1.
-
1:
Remote lock
On/Off
(Center). The indoor unit is being controlled by a BMS (Building
Management System controlled across to Modbus RTU Master device) and it can only be
managed by the BMS. In this situation, the MH-RC-MBS-1 is disabled for the On/Off
function.
-
2:
Remote lock
All
(Center). The indoor unit is being controlled by a BMS (Building
Management System controlled from Modbus RTU Master device) and it can only be
managed by the BMS. In this case, the MH-RC-MBS-1 keeps its status as disabled, like
when the device disablement register (7/8) is set to 1.
-
3:
