Pioneer 3 is an innovative system to control different channels independently. Combined with a pressurized water TCU, it allows to differentiate the thermoregulation on each channel. The system measures the return temperature of each channel and controls the flow by means of pneumatic valves. Flow metering is also possible for each channel. The version Pioneer 3/PWM controls the flow through ON/OFF pneumatic valves, while in the version Pioneer 3/PROP, the flow is controlled by proportional valves. The system works with pressurized water up to a temperature of 200°C (392°F).
Pioneer 3 is a modular system with 4, 8 and 12 channels. Combination of more Pioneer 3 systems extend the number of channels to a maximum of 96 channels, all of them controlled by the same main panel.
