Beskrivning
This is a partial driver for a Vallox air handling unit.
The protocol is Vallox Bus Protocol 31.12.20013.
OBS! The unit uses NTC temperature sensors with their own translation table. This driver implements a formula that gives resonable values in the 0-30 degrees Celsius range.
Values:
- Input fan (1=on, 0=off)
- output fan (1=on, 0=off)
- Supply air after cell temperature
- Exhaust air temperature
- Extract air temperature
- Error number
- Heating target temperature
- Cell defrosting (1=on, 0=off)
- Freezing prevention (1=on, 0=off)
- Supply setting temperature
Bruksanvisning
Sender emulates a control panel with address 33-47.
Receiver is one of the units mother boards with address 17-31.
The script has been tested with sender=41 and reciever=17.
