Connect the wires from the receiver to the remote control terminal strip on the indoor unit. (Polarity does not
matter)
Test Operation
Implementing a Test Run
1. Turn the #1 DIP switch [S003] on the receiver’s PCB
from OFF to ON and operate the wireless remote
control with its Start/Stop button.
2. During a test run, all display lamps on the display will
light up.
3. During a test run, it is not possible to adjust the
temperature.
4. After completing a test run, be absolutely sure to turn
the #1 DIP switch from ON to OFF and make sure none
of the display lamps are blinking. Also, replace the PCB
cover back as it was and fasten it; while holding the
wiring with the cable clamp, tighten its screw.
<Note 1> This is hard on the device, so only use this for
the test run.
<Note 2> After turning on the power, the unit will not
receive any commands from the remote control
for about 1 minute. This is not an error. (In fact
it does receive signals, but they are cancelled.)
Setting Address Switches
When more than one receiver and remote control are installed in the same room, setting up addresses allows
them to avoid interfering with each other.
Refer to the Users Manual for information on how to change the addresses of the remote controls.
Changing the address of a receiver can be done after removing the screw to the receiver’s PCB cover. Once the
change is complete, put the cover back in place; while holding the wiring with the cable clamp, tighten its screw.
