    Hi Frank,

    I came up with a less complicated solution (I hope!), but untested so far. I purchased a Xpelair Humidi/Timer Extract Fan (XPEC4HTR) which should power when required.

    I won't know...

    Any electrician with some boiler experience should be able to do that. All the wiring diagrams with various examples for different boiler configurations are in the Evohome manuals. Honeywell do have...

    Hi,

    Why oh why, when speaking to the majority of electricians and plumbers do I get a look of shock when discussing any form of automation?! Automation systems have been around of years yet I'm...

    Just read the manual (doh!). The max and min temp can be configured in the menu. Phew! This means I can set different max/min per zone based on our UFH spec.

    Is there a way to configure a T87RF2033 Single Zone Thermostat with a max temp. I'm concerned that if the temp set using thermostat can never be reached, the HCC80R will be constantly calling for...

    It's an open plan kitchen area (9m x 9m) plus a loop into the utility room. I'd rather avoid multiple zones as I'm nearly maxed on on zones for the evohome controller due to HR92's. Could the 6...

    I've just received the Nu-heat design, which shows manifold ports 1-6 for zone 1 and ports 7-8 for zone 2. Each zone is going to be controlled with a T87RF2033 single zone thermostat. Just noticed in...

    My wish list:
    1. Support for more than 12 zones per controller (other solutions support 30), I don't want to have to buy another controller.
    2. Future-proof hardware, I'm annoyed I have to buy the...

    Hi,

    I'm going to open this thread up again as our building work is underway and sadly I'm getting concerned that Evohome is going to restrict our selection of UFH floor coverings. Let me explain...

    Hi sharpener,



    I had assumed it was a requirement to have the manifolds within a certain distance of the different UFH zones. As the UFH will be spread across some 160m2. I will get back to...

    Evohome and Nu-heat UFH

    Hi all!

    I have an existing Evohome (colour) with boiler and HR92's for the upstairs radiators. All is working fine.

    The next part of the project is to remove the 60mm screed (sitting on...

    This is a phased deployment. The upstairs radiators have been replaced and have new Honeywell manual valves ready for the HR92's. I've left the downstairs CH zone controlled by the Evo controller as...

    Hi Ian,

    I can't help on the wiring, but it's possible they've been incorrectly wired. I have 3 x BDR91's next to each other and I have no issues. I did make sure they were installed at a distance...

    Hi Rich,

    I will need to check on the wiring and get back to you.

    Are you saying that Honeywell advises its installers to convert existing zoned CH (upstairs/downstairs) with two valves, to a...

    Hi,

    Thanks to a failed oil boiler, I took the opportunity to replace the 20-year old heating controls with a system based around the new colour EvoHome. Our plumbed system consists of a single...
