We are having problems with a Hitema water chiller. It is a 4 x scroll compressor unit with 2 refrigeration circuits.
The unit has tripped on high pressure activation. The manual reset HP switches do not appear to have been activated as there was no clicking or resistance when pressing the reset button.
Currently we are having a problem resetting the alarms on the IChill 200CX controller. The alarms being displayed are:
b1hp, b2hp, ctr1, ctr2, ctr3 & ctr4.
When entering the menu to carry out a reset 'no' is displayed. I believe that the 'no' requires that the alarm is cancelled in a higher level. We have tried in levels 1, 2 and 3 but we have manuals that conflict on the parameters that we need to enter. The ones we have tried do not work. We can easily reset any alarms that have rst displayed.
I am hoping that one of you chiller experts can shed some light on the controller and how to carry out a reset.
