I give up. I switch to bdr91 and praying that it works as it did in the other house. My last attempt was to change the r8810 in case it had a problem and it did not communicate well with the boiler. I have configured a single zone with the new opentherm relay, it does the same, the hr92 opens at P10 ...

In fact, if I do not screw the hr92 head completely, making the water flow with a small opening (no matter how small), the operation is optimal, but logically it is not the appropriate solution. De echo si no rosco del todo el cabezal hr92 haciendo que con una pequeña apertura (por pequeña que sea) ...

Once I have better understood each parameter of the boiler thanks to your indications I have managed to find the problem, but not the solution. The problem, as you said, is that although the zone has reached the setpoint temperature and marks 0% in the evotouch, it wants to heat the zone a little ...

I have tried many combinations in the parameters but not the one that you recommend, I definitely get on with it. The minimum OT setting is 10 degrees (parameter E 10-60). I would like to know what to put in parameter E. OT reaction (0 = ignore OT when <than E; 1 = limit OT when <than E; 2 = OT on ...

This operating logic seems very reasonable to me, I understand that when all the zones mark 0%, some hr92 is still a little open (for example, valve position 15) so that it waits for the temperature of that zone to rise somewhat before stopping. the entire boiler. This adding 12 zones makes the ...

I have placed a new evotouch and I have configured a single zone, as basic as possible. With a single zone it does exactly the same, it modulates until the zone's set point and the real temperature are equal, then it marks 0% on the thermostat and on the radiator (although the hr92 has a P16 valve ...

I will try to reprogram everything from the beginning, but the truth is that the behavior of the system is very confusing. It is as if when no zone demands temperature, the r8810 asks the boiler for just a little bit of heat, instead of that 0% for 1%, which makes it turn on and go into a loop. I ...

What confuses me the most is that the system works correctly if I remove it from the stable zone, let me explain. If I put the economic plan or off, the r8810 relay stops demanding the temperature of the boiler and it turns off, if I demand much more temperature than the real one in some area or in ...

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 l ...

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 ...
