Could you add points: 19,77 and 85 to your firmware?

Hi,

ID 19 - DHW flow rate, it is already supported.
What do ID 77 and 85 mean for your boiler?

[VladaWaas]

Hello,
thx for fast respose. ID19- flow rate is permanently zero on interface. Can I have any mistake in my setup?
ID 77 represented intake relative ventilation level 0-100%
ID 85 represented actual inlet fan speed in rpm

I don't necessarily need the last two values, but I thought why not show them if there was an option. :D

I have one more question about setting the equithermal constants.
I have
N = 1.2
K = 0.1
T=2
instead of power modulation, the boiler is switched off after reaching T-in 22°
which constant should I correct?

[Laxilef]

I will add polling ID 85 to the new version.

Well, not all boilers report this parameter.

Immergas is not in the OpenTherm association, but its extension modules are based on OpenTherm protocols. According to a non-public information from their developer, ID 19 should be active. But it is possible that the query string may differ in some small way from the OT spec.

I reading it last week. I did exactly according to your instructions immediately after installation. But I'm a pretty impatient person. Any intervention in the system has a long inertia. I will have to improve! :))))

Hmm, in the firmware we interpret response as float. Can you open the hot water tap and start logging?

yes I do. Can I acces via telnet in debug mode?

ID: 19 Request: 80130000 Response: 70130000 Attempt: 1 Status: INVALID
Your boiler responds with INVALID response to DHW flow rate request

[VladaWaas]

yes i noticed it as soon as i opened telnet. But I don't want to give up yet. I will ask the developer technician from the manufacturer if it is the same request at Imerrgas as specified by opentherm. Can you please send me the script of your command to fetch the values?

[VladaWaas]

so I don't have positive information :(
ID19 is active only in models with direct flow heating without a hot water storage tank
