Hope somebody can help.!
Basically replaced a faulty board on a york millennium screw chiller yae so415bsa, set dip switches 1-8 as on the old board, also used eeprom off the old board which is ok. Ive set in the programs that are accessible from the initial program menu, but when I come back to the status screen, im getting a message "reprogram type of refrigerant to run" ! Now when I check in 'options menu' the dip switch settings it tells me it is set to r407c which is what I want. However when I switch dip switch to r22 the reprogram message disappears and it is ok. But I need r407c! I have checked my eeprom again by putting it back onto old board and all is ok.... am I missing something that I need to program which I cant do from user manual? My head feels like its going to explode!!!!!
Thanks in advance. :-)
