Common Installation Issues
• E1 fault – if using 4 core method make sure that the W terminal has been switched to 1(L) at the condenser
• Power to indoor is fine but no display – check and double check the connection between the display board and the
main pcb
• Wifi dongle wont connect – the wifi signal requires 2.4ghz from the router. Make sure that this is not set to 5ghz.
Make sure you are trying after powering down the unit and restarting it. You have 8 minutes to set it up
• P1 error – make sure the service valves are open
• P4 error – make sure the coil is clear of debris. Check the connection between the compressor and main pcb
• Louvre wont fully close – switch of the unit via the mains power and restart. This will reset the louvre position after it
has been manually maneuvered out of sync
• Low heat exchange performance – in order to protect the environment and stop non trained persons fitting Midea
equipment, all high wall split systems comes pre-charged for 5m liquid length. Does the system require additional
refrigerant?
• The app wont let me have two users registered with the same system – only one account can have the system
registered as a primary system. The main account must share the system to the secondary account who must add this
as a shared system
• I have an extra cable hanging from the display board labelled up ABCDE – unless you are connencting a KJR29B
hardwired controller this cable isn’t required. Feel free to leave it in place or remove it from the display board
