Zanotti Temp. Controller

[fredyR717]

Could someone please help with a problem I have with a Zanotti unit, I got to the machine, and it was my first time working on one. It had ERROR 9 showing, I cleaned out the condensor and switched off and on at the mains. It fired up and now its not going into defrost and the evap fan is not running (A massive block of ice) from something that was working fine a couple of days back. Also any literature on how the controller functions and how to access the parameters etc. Its for a 2,4m x 2,4m x 2,4m freezer room that runs on R404. many thanks

What is the controller make and model?
Zanotti is not a controllers manufacturer.

Try changing the evap probe, on some zannoti's
evap fan is controlled by coil temp.
