The cooling controller ST181-VP4KAR.112 offers a high power at considerably small loads, and thus optimal installation possibilities for design-oriented refrigerators. Behind the elegant front, four power exits run a high switching performance. The relays can switch 16A each at 230V mains voltage, for engines (compressors) 1HP is the maximum performance.
Beside the refrigerating chamber sensor, a second temperature sensor for the evaporator can be activated. This allows economic and technically optimised defrosting, both with passive and active cooling with electrical heating elements or hot gas. There is a reserve exit for lighting or other functions.
The timer allows a 1-week time management for the defrosting periods as well as for setting the cooling chamber temperature at night or on the weekend.
Networking of the controller takes place via the ST-Bus interface.
