〈When including a BS unit〉
[PRECAUTIONS]
There is not need to set the indoor unit address when using group control. (It is automatically set when the
power is turned on. ) However, since the HRV (outside air processing type) uses two remote control
addresses per unit, the number of units which can be group controlled is as follows.
No. of indoor air conditioner units
No. of HRV units
Note
If a simultaneous cooling system is used, a single BS unit should connect to HRV (outdoor air-processing
type) and indoor units under group control. If a single BS unit connects to the HRV unit only, fix the
operating mode of the HRV unit to cooling, heating, or ventilation.
