- One air-conditioner connecting adaptor (SkyAir adaptor, etc.) is counted as one group.
- One Di unit is counted as 8 groups.
- One Dio unit is counted as 4 groups.
- When the output of Dio unit is set to an instant contact point, one unit is counted as 2 groups.
* Regarding Di/Dio units, if you specify the number of groups to be connected to each unit, you can reduce the number of groups
connected to one unit.
