Greenstar 28i with digistat optimiser

I have installed a tado system into our WB greenstar 28i which has the digital clock /RF unit. The tado works on its own and you can hear the relay click when you set a demand for CH, but this does not fire the boiler. The remote Digistat optimiser still operates the CH, and I can't figure out how to change this over. Any ideas?

  • Hi @Billbells52. Two things:

    1. Contact Tado via the App, explain that you have no heat - this is important to be prioritised.
    2. Would you explain what you did when you installed your Tado kit?
      1. Identify the Tado products you've put in place.
      2. What mode did you set them up to work in? That boiler has two potential modes in which Tado can engage it:
        1. The simplest way, is to wire in in what Tado call R01 mode (Relay) whiich is wired into connector ST10.
        2. The one with more long term benefit is to wire it in what Tado call D17, HT-BUS mode, which engages the Greenstar boiler's EMS-BUS (aka E-BUS, and which Tado call the HT-BUS connection).

    Having been on this forum for about 11 months, have noticed that the Greenstar series can have glitches in its implementation but a few people have found ways through it. The most common solution is to dismount the ribbon for the front panel controller - however would suggest that you search through the Greenstar threads and see if something makes sense for you.

    If you are still uncomfortable let us know and we'll ask a few people who've handled this themselves in their own homes, and hopefully they'll have something to offer. We tend to have a full response within a week from members.
