Hi all,

I am having one unit of neslab chiller is failing for temperature setpoint.The unit model is Merlin 33,power supply is 115Vac,50Hz and single phase.
The problem is can't maintain the temp: setpoint.
Let say, example we desire temp: is +20 'C but the chiller run go through max: temperature and afterthat get back to min temperature, this cycle is repeatly.
Mostly, we want to know which part is may be faulty.
So anyone can help me about this problem.

Thks & Best Regards,
Bill
