  1. Hi All Kingspan Aeromax ASHP fault 22 Looking for any thoughts on A Kingspan Aeromax ASHP Recently had a call to look at one which was tripping the main mcb, which was identified as the inverter board eventually got to speak with Carrier and sourced a replacement inverter, this was fitted which aliminated the initial fault. However I now have a alarm 22 temp sensors, I have checked these both where reading the same including the cables back to the control pcb. I have a nagging memory from looking at one of these years ago the water temperature needs to be above a minimum value, I am failing to get any assistance from Carrier tech possibly down to the COVID restrictions etc. I don’t have a back up heater to boost the temperature unfortunately. If anyone has any experience of these units that can assist I and the home owner would be very great full. Marcus
