Hy all,

had a nice one today,looking for a fault on a chiller (mcquay 45Kw) ho made the main jumper tripping by switching on the main button.the chiller was constructed for cooling only and worked normal for 6 years.the fault was a thermo sensor on the plate heat exchanger for working in heating mode. WHY do they build units and put parts in that they never going to use anyway? it was connected to the electrical board but has no use.
something to look out for,unused connected extra parts.:rolleyes:

Perhaps it was on of those

"It might come in useful one day" parts ;)

It is common place in modern manufacturing practices

I refer to it as Fault by Unecessary Component, Knowingly Engineered at Design.

If the acronym is inexcusable please feel free to delete.

Maybe because they use same controller for cooling only and for heat pump models. If they disconnect or not place that probe at all, then controller will register that as faulty probe and then stopped operation with error announcement.

Nop, disconnected the sensor and everything works normal,no fault codes, no differences in temperatures. its like Trash101 pointed out,its a "****ED".

Plank!

Think yourself lucky!
I recently had to set up two new units from the same manufacturer, only they forgot to fit the discharge temp sensors - "Discharge temperature fault 999.9c" :eek:

Ice, it was joke! :cool:
Don't take it personally! I also have found that European (and US) product quality is worse when manufacture day is Monday.:D
