How to control the Cooling Block temperature with a pwm driven pump via PID (or bang-bang)?

Water cooling can be that strong that you want to reduce the cooling power for the hotend.
I have a Thermistor in the cold part of the hotend and like to PID-control the temperature of the cold end, which is water cooled.

How can I tell the temperature_control module not to heat but to cool?
Or is there another solution?

Hi,
What do you mean cooling block? Are you referring to the heat sink on a 3D printer or some other application? You need to better describe what you’re doing if you want help, from what you’ve written, it’s confusing.
