Mitsubishi Ecodan fault code

[Leesparkykent]

I wired up two 14kw mitsubishi ashp at the same property last year, had to use a kanmor 264e and wire it in conjunction with both flow temerature control units to sequence the units, the kanmor also has weather compensation so it only runs 1 unit at a time or both if it needed it. Good bit of kit but gave me a few headaches installing and programming it lol.

Out of interest what was the correct sequence Rock?

All off, turn on the internal/tank controller first, then the compressor after a couple of minutes.
