    Probably the best thing that Honeywell could do right now is open the Evohome controller up to developers. The hardware is, for the most part, pretty good with only minor niggles. The software is...

    I would say that it can be done, because you could use the DHW kit but never actually install the thermostat, just leave it in free air. The system will never sense that the tank is hot, therefore...

    I'm not sure what you want is achievable with evohome. If you want to use wireless TRVs (HR80s or HR92s) then you need them fitted to every radiator. If I've understood your current setup correctly,...

    I can't explain why your pressure isn't fluctuating any more, but I am not at all surprised that removing a litre of water dropped the pressure by about 0.8 bar. Remember that water isn't exactly...

    You're right, it isn't possible, because evohome seems to consider economy mode in the same way as any other mode. To my mind, it would make far more sense if economy was considered a separate...

    I suppose it depends on your work schedules, but is it really a problem? On the average day, we only use hot water early in the mornings before work and in the evenings for washing up and the...

    I'm not sure why everyone is suggesting that re-using the existing wiring centre will be such a hardship. Seems like it should just be a case of the following:

    - Remove all wiring to existing...

    Rotor, can you post a picture of the inside of the wiring centre?

    EDIT: I did post some directions a few moment ago, but realised I made a bit of a ****up. Will re-post again later when I get...

    I don't see why not. If sticking with S plan, all that would be required would be change the wiring on the room start and programmer terminals. Some of the wiring may become redundant, but that's...

    Sounds like it would work, if all you want is on/off control. However, in your original post, you spoke about full control over each zone. That, to me, suggests that you should be able to remotely...

    It all depends how you're going to run the system. If you check pages 42 and 43 of the installation guide, you'll find some sample systems. Will you be fitting a HR92 to every radiator, or having the...

    Pretty sure you can have a T87RF for every zone (so up to 12) with evo. As far as the controller is concerned, it doesn't care whether the temp sensor is a HR92 or a T87RF. The limit you mention with...
  13. Three T87RF/BDR91 packs and the evohome...

    Three T87RF/BDR91 packs and the evohome controller should do it, but it's still an expensive proposition to only gain web based control. How many radiators do you have? If it isn't many, you might be...

    You only bind one sensor for the zone, but you can bind as many actuators as you like. Pick the HR92 that's in the most sensible place to measure the room temperature to be the sensor.

    Had the same problem in my master bedroom, just unlocked and removed the HR92, spun the top of the valve assembly fully counter-clockwise and refitted the HR92. It ran through a cycle and has, touch...

    I doubt you can do it, if I remember correctly then you need to set up a sensor and an actuator for the zone before the evo touchscreen will let you complete the device binding process. Even if...

    Hopefully someone from Honeywell will reply, but I very much doubt it's signal strength. More likely it will be to do with the discharge curve of the battery, allowing the HR92 to make a good attempt...

    You could buy a 'dumb' 868Mhz repeater and see if that gives you any joy. I'm not hopeful, but at less than $25 it has to be worth a pop:

    Dave's instructions above should get you going, but I would also add that using the earth conductor for anything other than earth is poor practice, even when sleeved as a live conductor at either...
