    Hi everyone,

    We have what I think is the Mira Platinum Ceiling Fed High Pressure/Combi Boiler shower that was installed by the previous owners of our house (Mira Platinum Ceiling Fed - High Pressure / Combi Boiler by Mira Showers)

    We had to replace the wireless controller a couple of years ago, but now we're getting this icon appearing: 20180811 090201

    When changing the batteries 'r03' appears. I've tested the fuse and power to the valve unit which is all fine. I've then gone through the re-registration process several times, (power down valve unit, press and holding power and + until END displays, power up valve unit, press power and +), but this always then displays ERR rather than SET.

    Is there anything else I can check before calling Mira out?

    Many thanks,

    The symbol in your picture means it's out of range...when you repaired to mixing valve did you bring controller next to the valve and go through the pairing process's?

    The mixing valve is in the loft and I was standing directly underneath it, so less than 1 metre away. A lot closer than it normally is when it's in the bathroom.

    I would suggest standing inches away from the unit in the attic and try pairing it again.
