Vaillant ecoTEC pure automatic modulation and SetMode #242
Comments
Hello, based on #170 (comment) I redefined the record for SetModeOverride to:
I also redefined the invocation to:
and the boiler has started increasing its power after several minutes:
I will check during the winter how long it take the water to heat up. I have old charts to compare. Now it's too hot outside to turn heaters on for longer time. Thank you @wizu to guide me to the right topic. |
Hello @pawelmuszynski |
Hello @HiQual Answering to my previous question it looks like my change on SetModeOverride works fine with modulation. |
Hello @pawelmuszynski |
Hello,
I have Vaillant ecoTEC pure VC 226/7-2. It's detected as a MF=Vaillant;ID=BAI00;SW=0709;HW=1303. Configuration loaded: "vaillant/bai.308523.inc", "vaillant/08.bai.csv"
I'd like to emulate a room controller (like VRC700, etc.). I read that it sends SetMode command every 10 minutes and I checked when I stop sending SetMode, settings will be reseted after 20 minutes. According to john30/ebusd#179 (comment) I created SetModeOverride to have ability to send proper message. It turns out when I send "0;60.0;45.0;-;0;0;0;0;0;0" value my gas boiler keeps water at 60 degrees but the automatic modulation doesn't work. It works at minimal power (25%). When I send "-;60.0;45.0;-;0;0;0;0;0;0" value, ebus controller is not in use (d.90 register shows 'off') and automatic modulation starts working fine but the boiler doesn't use the values and set the water temperature to 55 (it's also showed in d.05 register) It looks like it's a default value when you stop sending SetMode (SetModeOverride). It's set manually in the boiler. Can someone show me what values of SetMode are sent by room controller? Or how to enable automatic modulation during sending SetModeOverride?
EDIT: Even if I set it to "0;-;-;-;0;0;0;0;0;0" ModulationTempDesired is suddenly decreased to 25%.
