Programming option, Viessmann B2HA
I yet again find myself in the highly unfortunate position of having to commission two Viessmann Vitodens B2HA boilers and the display of ancient hieroglyphics they call a control. I need to run them without the outdoor sensors for a week or so while some other work is completed on the building but the boilers don't like to run without it and they go into alert which is not ideal.
If someone here knows how to program the boiler to ignore the missing outdoor sensor, I would thank you for passing that process along to me.
