Prohibited items
1. M-NET and MA remote controllers can not be connected to-
gether to the indoor unit within the same group.
2. MA remote controller of 3 units or more can not be connected
to the indoor unit within the same group.
3. When the total number of indoor units exceeds 26 units In-
cluding that above Type 200, a transmission booster is re-
quired.
4. In the case when start/stop input (CN32, CN51, CN41) is used
by indoor group operation, the "Automatic address set-up"
can not be employed. Please refer to 1. (2) " Manual address
set-up."
5. For the connection of LOSSNAY with more than 2 units in a
