I am experimenting with a dynamic glycol temperature setpoint. Basicly what I want to do is make the glycol temperature related to the beer setpoint with a static offset, for example the glycol must be 10 degrees cooler that the beer setpoint.
Well I got that working but the think I am struggling with is that my glycol chiller won’t go lower that -2,5 degree. I want to implement a minimum setpoint for the glycol to prevent the compressor from running constantly because it cannot reach the setpoint of below -2,5 degree.
Is this possible?
