6.7. Remote sensor (optional parts)
For the installation method, please refer to the INSTALLATION MANUAL of remote sen-
sor.
Connection method
• Remove the existing connector and replace it with the remote sensor connector (ensure
that the correct connector is used).
• The original connector should be insulated to ensure that it does not come into contact
with other electrical circuitry.
• Use conduit hole when external output cable is used.
Setting for room temperature correction
When a remote sensor is connected, set the function setting of indoor unit as indicated
below.
• Function Number “30”:
Set the Setting Number to “00”. (Default)
• Function Number “31”:
Set the Setting Number to “02”.
* Refer to “7.4. Function setting” for details about Function Number and Setting Number
6.8. IR receiver unit (optional parts)
Connection method
• For the installation method, please refer to the INSTALLATION MANUAL of IR receiver
unit.
(1) Use 9 pins for receiver unit cable.
(2) At first, connect the receiver unit cable to the controller PCB.
(3) Attach the core that comes between controller PCB and the clamp.
(4) Use conduit hole when external output cable is used.
6.9. Drain pump unit (optional parts)
• For the installation method, please refer to the INSTALLATION MANUAL of drain pump
unit.
