3.15.5 20-4* Thermostat/Pressostat Function
The Thermostat-Pressostat Function (TPF) can be used to stop and start the compressor when running in closed loop. The TPF monitors and compares
the resulting feedback with the Cut-out value in par.20-41. When the resulting feedback gets below par. 20-41 a stop signal is generated and the
compressor stops. When the resulting feedback gets above the Cut-in value in par. 20-42 the stop signal is removed and the compressor starts again.
The Set-point should be set to a value in between Cut-in and Cut-out.
