Address Setting - Toshiba MCY-MAP0401HT Installation Manual

Regulation of high frequency wave
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to Ssc (*1)
at the interface point between the user's supply and the public system. It is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is connected
only to a supply with a short-circuit power Ssc greater than or equal to Ssc (*1)
Furthermore, when similar equipment or other equipment which may cause harmonic current emissions are to be
connected to the same interface point with this equipment, to reduce the risk of possible problems which may be caused
from addition of those harmonic current emissions, it is recommended to make sure that the short-circuit power Ssc at the
interface point is greater than the sum of the minimum Ssc required by all the equipment which will be connected to the
interface point.

3. It requires a maximum of 10 minutes (Usually, approx. 5 minutes) to automatically set-up an address for 1
system.
4. To set up an address automatically, the set-up of the outdoor unit needs to be completed.
(Address setup cannot be performed by power-ON only.)
5. To set up an address, the air conditioner does not need to be in operation.
6. Manual address setup is also available besides automatic setup.
Automatic address : Setup from SW15 on the interface P.C. board of the outdoor unit
Manual address : Setup from the wired remote controller
* It is temporarily necessary to set-up the indoor unit as a 1:1 using a wired remote controller.
Automatic Address Setup
Without central control : To the address setup procedure 1
With central control : To the address setup procedure 2
(However, go to the procedure 1 when the central control is performed in a single refrigerant system.)
(Example) In case of central control in a single refrigerant system In case of central control over refrigerant system
