Answers
Up to 8 controllers.
• The same address cannot be assigned to multiple remote
controllers
• If the same address is assigned to multiple controllers, the
address can be assigned to only the last paired remote con-
troller.
• Once the remote controller is paired, its pairing address
cannot be changed by remote controller. Use the wireless
receiver to reset pairing information.

• The batteries on the wireless remote controller are running
out.

cations on the main controller and take appropriate measures.
Please also check installation and service manuals for the in-
door unit.

ure. Check the resistance of the thermistor. (When the room
temperature is between 0 and 40°C, the resistance must be
between 5 and 28 kΩ.)

controller and the wireless receiver. Check the following pos-
sible causes.

ler does not reach the wireless receiver.
