First off, I am not quiet sure if I have the right forum here, but anyway if there is someone who has any ideas on the following that would be great. I have a climate master geothermal heat pump installed with a garden collector fitted. I am getting an error message E02 on the display, which is preventing the heat pump from working. I do not have any info on these messages. I have tried contacting the climatemaster office in Ireland but I have been unsuccesful in contacting them. Any advice??????
