[4] An Example of a System to which an MA Remote Controller is connected
1. System using MA remote controller
PFAV-P500VMH-E and PUHY-P500YSHM-A
(1) Sample control wiring
(1) Cautions
1) Connecting the terminal block (TB5) of a different refrig-
erant indoor unit in a daisy-chain is prohibited.
2) Three or more MA remote controllers cannot be connect-
ed to indoor units in the same group. If there are three or
more indoor units, ensure there are no more than two MA
remote controllers.
(2) Maximum allowable length
1) Indoor/outdoor transmission line
Maximum distance (1.25 mm
2
[AWG16] or larger)
L1+L2 200m[656ft]
2) Transmission line for centralized control
No connection is required.
3) MA remote controller wiring
Maximum overall cable length (0.3 to 1.25 mm
2
)
[AWG22 to 16])
m1+m2 200m [656ft]
(3) Wiring method and address setting
1) Indoor/outdoor transmission cable
Connect terminals A and B of the terminal block (TB3) for
the indoor-outdoor transmission cable of the outdoor unit
(OC, OS) and terminals A and B of the terminal block
(TB5) for the indoor-outdoor transmission cable of the in-
door unit (IC). (Non-polarized two-wire)
* Only use shielded cables.
[Shielded cable connection]
Use the earth of the shielded cable to connect the earth
terminal of OC ( ) and the S terminal of the IC terminal
block (TB5) in a daisy-chain.
2) Transmission cable for centralized control
No connection is required.
3) MA remote controller wiring
* This cable is not needed when operation will not be per-
formed with two remote controllers or a group.
[In the case of operation with two remote controllers]
In the case of two remote controllers, connect terminals
1 and 2 of the IC terminal block (TB15) and the terminal
block of the MA remote controller. (Non-polarized two-
wire)
* Set the connected MA remote controller to the sub re-
mote controller with the main/sub setting. (Refer to the
operation manual for the setting method.)
The MA remote controller is built into the indoor unit.
4) Switch Setting
Refer to Chapter 3-[2]-(1) "Address Setting". (page 19)
