C3 control

This control unit is specially programmed to control air-water
chillers and heat pumps with four capacity stages. These

are distributed in two independent cooling circuits with two
tandems that act upon a common water circuit. Both systems
have two fans each, with speeds controlled by pressure sen-
sors. This control unit operates by means of the following
intakes and outlets.
