Arcadia T250 Chiller Hysteresis value?

[Loonsbro]

Hi

just wondering if someone here is able to help :-) so i have a T250 chiller that has been running fine for a few years. Over the weekend my 2year old grandson managed to change the hysteresis setting on the menu. Looking through the destruction book it says in big print not change this figure but what it fails to say is what the figure should be if it happens to get changed?
thanks

Hello!

What are the values if you cycle through them?

Basically hysteresis is the difference between the on/off cycle temp and the setpoint.

Example, chiller setpoint at 78 degrees and it would cool until 77 degrees before it turned off and then turn back on once its probe sensed 79 degrees.

Thats a hysteresis value of 2

I would set it at 2 degrees and observe the chillers cycle and ensure its not short cycling.
