The SZ-CR2 is a Two-Compressor Controller with separate Set Points for each
Compressor. They are specifically designed for Refrigeration applications wherein the
Compressor cuts off at Set Point and is restarted at a Temperature of Set Point plus
Differential. Amongst other features, an important one is that in case one Compressor
is not capable of handling the load, the second Compressor will activate and both
Compressors will cutout at the lowest Set Point.
