Simultaneous Operation - York TIWM006B21S Engineering Manual

OPTIONAL PARTS

3.3.10 Simultaneous Operation

● Turn OFF the power supply completely before setting the DIP switch and electrical wiring work for the
IR receiver kit. Not doing so can cause an electric shock.
● Accurately perform the electrical wiring work. If the electrical work is not completed correctly, heat
generation at the connection, a fire, or an electric shock may occur.
● Make sure that the electrical wires are adequately clamped with a cable clamp and not in a manner that
applies too much external force to the terminal connections of the wirings. If done correctly, the result
could cause heat generation or a fire.
● Do not run the connecting cable for IR receiver kit and the power supply cable (208/230V) in parallel.
It may cause a malfunction of the IR receiver kit.
Up to 16 indoor units can be simultaneously
controlled using one wireless controller.
When multiple indoor units are installed in a large
room, all the indoor units can be controlled to start/
stop with only one wireless controller.
NOTE:
Do not apply a simultaneous operation for the indoor
units installed separately in different rooms.
Some units may be left without turning OFF the
power supply.
Installation of IR Receiver Kit
In an instance of simultaneous operation of multiple (up to 16 ) indoor units by the wireless controller, install
the IR receiver kit only to the unit to be operated. Other units should be the standard units without the IR
receiver kit. If multiple IR receiver kits are required to be installed, two IR receiver kits are the maximum.
