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.
