Beskrivning
This is a driver to set Vallox Air handling unit's supply temperature and cell bypass temperature setting.
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.
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.
