General description
The
XW 40L
is a regulator with microprocessor aimed at medium or low temperature refrigeration applications. It
has 3 relay outputs to control the compressor, light and ventilator and 1 NTC or PTC probe input to control
temperature.
Regulation is obtained by the temperature measured by an atmospheric probe with positive differential with respect
