TEMPERATURE SETTING AND CONTROL THE ECP COOLER
The gas cooler is set by manufacturer to a control temperature of +5°C.
This temperature can be adjusted with a trimmer Potentiometer P3 within a range of 0°C to +20°C.
This Potentiometer is located in the ECP ..000 case behind the front sheet metal.
Turning clockwise will increase the temperature and turning counter clock will decrease the
temperature respectively.
To set the temperature it is measured at the reference terminals yellow (X7/2) and blue (X7/3) using
an external DC-Voltmeter (0,1Volt/°C).
