Ciat chiller trip

[twisty]

Hi everyone,

I'm looking for some information on a controller for a
Ciat water chiller/heat pump,
My problem is possibly a HP trip due to recent warm weather but there is no manual on the site and a reset allowed it run for a couple of days.Pressures seem fine.
Is there a way to check alarm history from the PCB?
I'd be grateful for any service manual or links!

details; AQUACIAT ILZHE year 2003

Thanks!

Which user interface uses.
Does "Connect" or Carel

Hi Sasa,It doesn't have an interface,the PCB has a basic LED display and displays a "P" value with up and down arrows,a button marked"ESSAI" and a button marked "reset"
there is about 30 parameters accessed by the arrows which can be modified but i don't know what they represent?
