arduino-xpl-heatpump-controller

Control a Panasonic heat pump/split unit air conditioner with Arduino using the xPL protocol Currently supports at least models

  • Panasonic E9/E12-CKP and E9/E12-DKE (Panasonic remote control P/N A75C2295 and P/N A75C2616)
  • Midea MSR1-12HRN1-QC2 + MOA1-12HN1-QC2, sold as Ultimate Pro Plus Basic 13FP in Finland (Midea remote control P/N RG51M1/E)

Some xPL-perl example commands:

xpl-sender -m xpl-cmnd -t xpl-arduino.heatpumpctrl -c aircon.ckp power=0 mode=2 fan=3 temperature=23
xpl-sender -m xpl-cmnd -t xpl-arduino.heatpumpctrl -c aircon.dke power=0 mode=2 fan=3 temperature=23
xpl-sender -m xpl-cmnd -t xpl-arduino.heatpumpctrl -c aircon.midea power=0 mode=2 fan=3 temperature=23

Supported parameters

  • Common to Midea and Panasonic CPK and DKE-series
    • power
      • OFF: 0
      • ON: 1
      • Note! There is no direct ON/OFF command on the Panasonic CKP series. As a workaround the timer is set to stop or start the unit in one minute from the current time

Bill of materials

  • Arduino :)
  • Arduino Ethernet shield
  • IR led
  • 1 kOhm resistor for the IR led

Connect an IR led (with 1k resistor in series) between GND and digital pin 3
