NOTE It is not necessary to designate indoor unit address
when using group control. The address is automati-

Precautions
1. A single switch can be used to supply power to units on the
same system. However, branch switches and branch circuit
breakers must be selected carefully.
2. For a group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions.
3. Do not ground the equipment on gas pipes, water pipes, light-
ning rods or crossground with telephones. Improper grounding
could result in electric shock.
Control by 2 Remote Controllers (Controlling 1 indoor
