Hello everyone! I do not speak English, so I will use google translate.

Compressor - single screw with stepless capacity control. From 25% to 100%.
Controller - Microtech III MT3006. Manufactoring date 2012.

With an increase in productivity, the compressor is working properly. By lowering the performance controller Microtech III displays the % decrease in performance, the solenoid valve can hear the clicks. But evaporation pressure and condensation mode the compressor is not changed. By lowering the productivity of up to 25%, there is a sharp jump in pressure, and a compressor actually starts to work by 25%.

Where to find the principle of work the solenoid valves manage the capacity ogf the compressor?
