Intergas hr36/30 Evohome R8810 opentherm

[Jb1577]

The first thing to say is sorry for my English.
I have an intergas hr boiler, a system with 12 zones evohome integrated wifi version with hr92 headers and the r8810 thermostat.
My boiler turns on and off constantly, I have played with the boiler parameters and I cannot make it work, even when the opentherm appears at 0% in the evotouch, the boiler turns on even though all the radiator valves are also closed at 0 %
I need help, I'm desperate.
It was mounted on the same system in my previous home but with a br91 thermostat and it worked wonderfully.
That modulation thing is driving me crazy.
Thanks in advance.
a greeting

Lo primero pedir perdón por mi inglés.
Tengo una caldera intergas hr, un sistema con 12 zonas evohome versión wifi integrada con cabezales hr92 y el termostato r8810.
Mi caldera de enciende y se apaga constantemente, he jugado con los parámetros de la caldera y no consigo hacerlo funcionar, incluso cuando en el evotouch aparece el opentherm al 0% la caldera se enciende aunque todos las válvulas de los radiadores estén cerradas también al 0%
Necesito ayuda, estoy desesperado.
Tenía montado en mismo sistema en mi anterior domicilio pero con un termostato br91 y funcionaba de maravilla.
Eso de la modulación me está volviendo loco.
Gracias de antemano.
Un saludo

Anybody?

It will be an RF comms issue with the OT Bridge or something not switching 100% off.

I also believe that because all the zones and the r8810 appear at 0% and the boiler does not turn off is not normal, also if I physically disconnect the r8810 the cashier if it turns off.
I have gotten another evotouch to rule out that, if it is not the reason I would only need to check the r8810 opentherm, but if someone who has had the same problem can better guide me where to look for the fault, I would be very grateful.
Thanks for the reply

Eso creo yo también porque que todas las zonas y el r8810 aparezcan al 0% y la caldera no se apague no es normal, además si desconecto físicamente el r8810 la cajera si se apaga.
He conseguido otro evotouch para descartar que sea eso, si no es el motivo sólo me faltaría comprobar el r8810 opentherm, pero si alguien que haya tenido el mismo problema me puede orientar mejor por donde buscar el fallo estaría muy agradecido.
Gracias por la respuesta

The OpenTherm Bridge keeps doing what it was last told until it is told to do something else. If the 0% command doen't get through because of RF comms between it and the evohome Controller, it will carry on doing what it was doing last.

We have two OpenTherm systems setup here running on 17.03 firmware and they operate as expected.

Do you have any pictures of the installation?

And in this situation the boiler is always on with the radiator icon given and logically all the hr92 radiator valves closed

Y en esta situación la caldera está siempre encendida encendida con el icono del radiador dado y lógicamente todos las válvulas de radiador hr92 cerrados

And in this situation the sleeping chamber is on with the radiator icon given and logically all the hr92 radiator valves closed

OK, why is the evohome Controller used as the sensor in this zone? Can I have a wide angle image of your R8810 please?

In all areas I use external thermostats (dts92) somewhat far from the radiators to get a more realistic reading of the room temperature (since the hr92 valves are attached to the radiators). In the "living room" area instead of a dts92 I use the evotouch itself.
I already had it configured like this in another house and it worked correctly with the bdr91 on / off thermostat, the problem has come when placing an identical system except for the opentherm r8810 thermostat.
Here I do not have images of the set, but I will send some as soon as I can.
Thank you

En todas las zonas uso termostatos externos (dts92) algo alejados de los radiadores para recibir una lectura más real de la temperatura de la habitación (ya que las válvulas hr92 están pegadas a los radiadores). En la zona "salón" en vez de un dts92 uso el propio evotouch.
Eso ya lo tenía así configurado en otra casa y funcionaba correctamente con el termostato on/off bdr91, el problema ha llegado al colocar un sistema idéntico excepto por el termostato opentherm r8810.
Aquí no tengo imágenes del conjunto, pero mandaré alguna en cuanto pueda.
Gracias

OK, well I would go back to basics. Reset and setup just one zone with a HR92 and DTS92E. Get this working so you are happy first, then add another zone. It is painstaking this way, but only way you will find any errors.

I will reconfigure everything from scratch but this will be my fourth time.
I will use a new evotouch that I got from the installer.
I will comment on the results and if I have been successful.
Thanks and best regards


Lo volveré a configurar todo desde el principio pero esta será la cuarta vez que lo hago.
Usaré un nuevo evotouch que he conseguido del instalador.
Ya comentaré los resultados y si he tenido éxito.
Gracias y un saludo
