Does anyone have factory/service passwords for a lennox climaic 620 controller.I spoke to lennox they wouldn't tell me them as they say there for lennox use only.
I need to check the parameters for the system
thanks

i'm afraid getting blood out a stone comes to mind! i was told "all the manuals are on line, if you cant sort it from them you need a proper engineer a lennox aproved dealer" gob smacked, shocked and disgusted! i ripped out the controller and put my own design pannel in and unless necessary i wont deal with them again!!! good luck hope sombody else can help!!

sorted it out in the end lennox hed de configured two of the compressors due to water flow it never occured to their hot shot engineers to check the strainers why they did it electronically i dont know
