Hi, I have a 2009 York Chiller on a client site, model no. YLAA455HE on R410A. It went out on a low pressure fault recently, dug deeper and found the controller had reverted back to R22 refrigerant and all transducers were reading a lot lower than actual. Checked the program settings and found the Refrigerant setting, but was unable to change it back to R410A. Anyone got any ideas? Looks like it has defaulted to an R22 configuration?
