Lennox LCH Chiller

[SteveCass]

Anyone know of any access codes for these chillers? It has the LCD screen showing the chiller and individual circuits etc..

Cheers, Steve

I think you've only the DC50 display in the unit for userlevel?, for service you need also the DS50 servicedisplay, you can find further information in the manuals

[SteveCass]

you've lost me? The chiller has an LCD display on the front end, showing the chilled water flow and return and after some button pressing it can show the fridge circuits pressures etc. Its the one level used to access the setpoints (i think) that has some kind of password access section. I want to go in there and check HP settings plus fan diffs etc.

Any ideas?

most lennox kit uses a carel outstation for its control.the easiest way is unplugging j5 connector-telephone plug-plugging in a ds50 will allow access but at around £500 of lennox.plan b is usually a 4 digit code try 0000,1111 etc o4o6 is a common code.good luck
