c-pro 3 HPRU is a series of fully configurable controllers for running reversible air-water and water-water single-circuit residential heat pumps with up to 3 compressors.
As standard features, the controllers include the management of the DHW tank circuit (with stratification and priorities) and of the solar panels circuit. Complete control of BLDC compressors is given by the management of the "envelope” function , while unipolar stepper electronic expansion valves can be driven thanks to a built-in driver.
Optional features include the management of bipolar stepper EEVs through an external driver module.
The solution is available in the following hardware formats: - c-pro 3 nano (74x32 mm) with built-in LED display, capacitivetouch keys, 25 I/Os, IP65 frontal potection and panel fitting; - c-pro 3 kilo (4 DIN modules) in blind version or with built-in LED user interface, up to 31 I/Os, built-in driver for unipolar EEVs and DIN rail installation; - c-pro 3 micro (4 DIN modules) in blind version or with built-in LED user interface, up to 33 I/Os and DIN rail installation. Both formats can be connected, according to your needs, to the stylish panel- or wall-mounted interface EPJgraph or to Vled 3, a reduced-depth interface for panel fitting.
