Videos
The presentation films, the wiring and the before / after comparison, in one place. No sound, on-screen text in French, German and English.
EC-SWAP
The film
The film goes through the “automation” and “electrical wiring” lines of a retrofit quotation one by one, then shows what is left with EC-SWAP. 58 seconds, no sound needed.
The wiring on video
The existing two-speed motor cable connects as is to the PV-GV input; the output feeds the EC motor with 400 V three-phase, no neutral.
Terminal block J3 “MOTOR” is wired terminal to terminal, each label to the same label (24V · GND · D1 · E1); the motor fault signal arrives on J9 “FAULT”. The motor output stays live: a stopped motor is not de-energised.
98 seconds, no sound.
Before / after
Before: an induction motor with two fixed speeds. After: EC-SWAP sits between the existing feeders and the EC motor; the control selects the speed, the module translates it into a 0–10 V setpoint.
What changes: the connection of the contactors, one module per airflow. What stays the same: the control system and the controller program.
54 seconds, no sound.
WS-SMART-HG
The film
A boiler-room controller can be replaced without touching the hydraulics. The film shows the modules chained circuit by circuit, the detection of manually forced valves and stopped pumps, then the Modbus opening. 56 seconds, no sound needed.
WS-SMART-IO
The wiring on video
The bus arrives on J1 and leaves on J2 (24 VAC, Modbus RTU, A to A, B to B). The 230 V arrives on J10 and leaves on J11; the pump connects to J12 and its enable contact to J13.
PT1000 sensors on J14, safety thermostat on J5, 24 VAC actuator on J3. One address per module, TERM on ON at the last module only. Switch off at the cabinet before opening a module: the 230 V arrives through the chain.
52 seconds, no sound.
