WORKING IN PRESSURE (window visible only with this selection)
Working in PRESSURE allows the control of the condensation, evaporation pressure circuit. Working in the
pressure mode requires the input of other SETUP parameters, for a correct match with the characteristics of the
plant, from the equipment manufacturer.
