Controller not working


The units were set up as master/slave by removing a jumper on the indoor board of the 0V unit. The CENTRALISED CONTROLLER display was removed by changing one of the indoor boards dipswitch settings.

P8 eroor code


P8 error is abnormal pipe temperature indoor. If you are running it on heating P8 error will appear because the disc pressure is too high. It could be overcharged.
