Support newer version of Worcester HT-BUS

Acejames87

I just upgraded from a worcester bosch greenstar cdi to a worcester bosch greenstar 8000 life. On my old boiler I could connect to the digital low voltage interface bus however the new boiler the ht-bus is not supported and I couldn't simply change over I had to rewire to the old relay style. The bus interface is better and is easier to install. On the new boiler I could connect it but the tado just continuously called for heat even if the temperature was way above what was set. I think supporting these newer interfaces would really help sell Tado to friends and family with the ease of setup and not requiring to mess around with a 230v electrical current.

Any news on this? Would really like to use modulated control instead of the basic relay style interface.

Same here. I also have a greenstar 8000 life and would like to take advantage of flow temp modulation.

We are waiting

This needs priority

Got 18 Tado TRVs and had to replace the boiler - now have an Greenstar 8000. PLEASE can we have this working - otherwise it kind of makes no sense having the Tado kit.

Even the new controller (https://uk.installers-shop.tado.com/products/wireless-smart-thermostat-starter-kit-v3-eu-version) is still not compatible for modulation control

2023 and still not supported, is it really that hard to extend the programming on the thermostat to talk the same protocol?

Has anyone tried this yet, it looks like it might solve the issue?

This adapter is to use the Bosch EasyControl to control the below heating appliances:

• modulating heating systems with OpenTherm-protocol
• on/off-appliances and district heating systems
• older boilers with iRT-protocol

I doubt it would allow OpenTherm control of Greenstar 8000 Life boiler

It’s near the end of 2023. When will this be implemented? Lot of people have been asking this for last 2-3 years!!!!

Please implement this - lots of people in the same boat here

is there any alternative options to this? Getting rid of tado and installing something else? This on/off mode relay system is costing me a fortune!

Lemmings72

The only supported option for EMS is the WB own smart system. We have it but have just invested in Tado because it’s TRV heads are very poor. It was only during DIY installation that I found out that there are issues with compatibility. Does anyone have any idea regarding how much extra gas the on/off relay mode costs them. We have modulation but have had 5 x £75 TRV headers fail within 3 and a half years.
