    I see MsgID 17 Relative modulation level every minute.
    MsgID 0 containing Flame status almost every second.

    Do you still see the OTBridge requesting that information from the boiler? I canít monitor the Controller messages but do see these requests from the bridge with the OTGW connected.
  3. Which message stops with the OTGW connected?

    You could rotate the T87RF to set the temperature to 30C and look for the zone with this setting on the panel.
  5. There is no difference on the OpenTherm Bridge...

    There is no difference on the OpenTherm Bridge side, its green LED flashes every 10 seconds or so.

    On the OTGW, in Gateway mode, you should see a green LED lit when OpenTherm messages are...

    That's actually incorrect. If you refer to the "Weather - compensation adjustment" section in the Intergas manual you'll see "The maximum supply temperature (Tmax) is set via the temperature...

    Are you seeing the "Thermostat disconnected" message at any time?

    I have seen this happen. There was a period last week when RF interference appeared to affect Evohome and my Smart Meter display....

    Thatís very strange because in Monitor mode there is no firmware intervention to transfer data across the gateway. If you can just double check that no LEDs are lit, Iíll take another look at the...

    Bruce, when you have switched the OTGW to Monitor mode do you see any flashing LEDs?

    In Monitor mode you should see no LED activity and the OTGW should not be modifying data. If you are definitely...

    Thanks! Indeed as I found out, at least for me, the system works better with proportional temperatures calculated from a 90C maximum, rather than the 60C I have set at the boiler.

    So I ended up...

    When there is a DHW demand, Evohome will issue a 100% request to the OpenTherm bridge. The bridge will map this to your boilerís Max CH Setpoint water temperature. This is 90C with my Intergas...

    I ran a short experiment, reducing the Max CH Setpoint and found with it set at 60C, for an outdoor temperature of 5C, the proportionally lower requested temperatures via OpenTherm resulted in my...

    As you have both radiators and UFH, I can't think of an easy way to do this with Evohome. You could detect when the UFH pump is not running and stop the boiler, but there could still be a demand...

    The min run time parameter only applies to the boiler relay, not UFH relay.

    With the OpenTherm gateway the boiler will continue to run even when the UFH pump has stopped.

    I changed my UFH...

    Iím looking at adding weather compensation to my Evohome Intergas OpenTherm setup by customising the OTGW firmware.

    The good thing is that the OTGW can read the Outside temperature from the...

    Evohome HM80 does a great job of maintaining single zone UFH temperature compared to the BDR91 I used before.

    Temperature maintained within 0.2C over 4hrs this evening.

    I confirmed S4 is the DHW cylinder temperature reading. Also indicated I had an issue with my Priority DHW setup.

    One of the DHW BDR9s that was supposed to be normally closed and connected in...

    I currently see:

    S1 95.2
    S2 46.7
    S3 - (will try priority DHW later to see whether this returns DHW temperature)
    S4 53.2
    S5 -2.3

    Temp Flow 63.7
  19. Paul, are my guesses correct? Do you know?

    Paul, are my guesses correct? Do you know?
  20. Intergas Diagnostic Software S1-S5 temperatures

    Does anyone know what the S1-S5 temperatures logged in IDS are?

    S1 Flow sensor?
    S2 Return sensor?
    S3 DHW sensor?
    S4 ???
    S5 Outside temperature sensor?


    Thanks!

    Yes, that should be the case.

    Ian, you can configure how many hours optimum start will pre-heat, maybe you need to increase that parameter.

    It took a while (largely due to lack of support for this in the UK) but I now have the HM80 controlled solution for my single-zone UFH in place. And it works great, I no longer see the 1 degree...

    I donít see that as the issue. Evohome should be able to balance any heat loss for any zone when the set point is reached. As it stands, at set point, the zone still has a 50% heating demand leading...

    I think the key difference is that I am only heating our UFH zone in the evening. In an experiment, running 24/7, Evohome could maintain a stable temperature when the set point was set to the...
