Dear all, I would like to share this small long term side project for speed control of a water pump and an air pump to provide satisfying media throughput to allow for a strong bathtub massage on a budget. The Program takes commands from a quad attached KNX input (blinder up/down) switch with Long/Short press or manual control switches. It controls the external power drive systems. A sensor ensures that the required water level is within the allowed limits. In simulation mode, I1/I2 control the air pumpt and I3/I4 the water pump. I7/I8 are the the main power drive switches. The water level input is set with AI2. Leakage alarm is not implemented yet as are three electromagnetic valves to allow for different air flow. The logic detects short/long presses and determines a preset value for the motor outputs. ZIP File with photos and the .lsc file attached.
