Hi!

Due to a faulty display on a "ciat LW M 1600z 2" I was forced to replace it. After the switch I have noticed that the machine can't manage to get down to the desired setpoint (as it did before). The machine goes down to 0.5 degrees from setpoint but never stops. I reckon it's a problem with the capacity regulation because the capacity used lowers when the water temp lowers but it never gets down to setpoint. It may be a small problem but as it never stops it can't switch the running compressor either so I'm currently only using one comp all the time. I have checked every parameter I can think of but I must be missing something. (Another weird thing is that I cant access the parameter p24 which is the parameter for min position of slide valve.)

Has anyone had the same problem before? Anyone got any pointers?

Kind regards

Fredrik
