Hello
Yesterday i successfully build and run OpenthermGateway with ventilation only device: Viessmann Vitovent 300. The transmission log file is already uploaded to device matrix.
I found only one problem with timings in transmission from controller(thermostat?), something is wrong with last "bit" (see attached file with diagnostic). This results in Error 01(or Error 03 if ignore non-significant transitions) in transmission:(.It is possible to workaround this problem?
My second question, is there a possibility to override "Control setpoint V/H", like for heating?
In otmonitor for few msgId("Relative ventilation","Control setpoint V/H",... ) program shows only one byte of data but important information is in the second byte .
Regards
Michał Konopiński
Edit:
Changing firmware to gateway-4.0b1.hex removes all transmission errors
Edit2:
I'm found some documents about this device:

Re: Viessmann Vitovent 300 Opentherm Gateway
I have added a VS command in firmware version 4.0b3, that will allow you to override the Ventilation Setpoint. Since I don't have a ventilation/heat-recovery system myself, I could only do limited testing. Please let me know whether the command works correctly.
I will fix the incorrect display of the V/H message ID's you mentioned in the next version of otmonitor.

Thnk You,
it looks like it works fine, but how to cancel this command?
The descripion for VS command may be inappropriate in my case, the controller sends only 3 special values:
0 - Off
1 - Reduced ventilation
2 - Standard ventilation
3 - Maximum ventilation
the values for this modes can be read/write by "TSP setting V/H" command.

Re: Viessmann Vitovent 300 Opentherm Gateway
You can cancel the override by specifying a non-numeric value, e.g.: VS=-, or VS=N.

Yes, it works
I checked more closely :
0 - Off
1 - Reduced ventilation
2 - Standard ventilation
3,4,5 - Maximum ventilation
6-16 makes ventilation at 16%(probably technical limitation, ventilators can't go slower?)
17-100 makes ventilation at 17% to 100%
>100 makes 100%
For me, everything works even better than I expected, thank you very much
