Valve Node

This is a peripheral slave controller and valve added to a Node-HIU controller using USB. Up to four peripherals can be added before a USB hub is required.

  • iHIU-Micro slave controller
  • ESBE control valve (2s travel, Kv=5m3/h, 1.5 bar DP max)
  • Digital temperature sensor, bus based to enable additional sensors
  • Enclosure for Micro

Not the Micro expands the input/output capability considerably, adding realtime PWM outputs and analogue inputs, and can be used to interface with other sensors and systems - in this case the ESBE control valve. Uses include:

  • Control over heat exchange process
  • Underfloor heating temperature control (weather compensated by internet data)

Other Peripherals

All Node-HIU controllers can make use of various peripherals to add functionality.

  • Camera - for taking photos or providing remote monitoring services.
  • Speaker - to add sound and internet radio.
  • USB Power Pack
  • Ethernet Cable, 0.5m
  • Ethernet Cable, 5m
  • Ethernet Cable, 25m
  • USB Micro Cable

Switches

  • 4 port PoE Switch
  • 8 port PoE Switch
