Opentherm controls for Ethos boiler

[coolblue13]

After much searching and comparing of spec's, I've finally ordered an Ethos 54 boiler. Finding a supplier of the boiler was hard enough but it's turning out to be nothing compared to trying to buy Opentherm thermostats/controllers.

Could anyone recommend thermostats/timers/outside sensors (description and model numbers would be appreciated) suitable for this boiler and where I can purchase these from?

Are the benefits of Opentherm protocol kit worth searching it out?

I've not yet tried any of my local plumbing & heating merchants but can't find any suppliers on the web.

Danfoss-Randall make Opentherm controls.

Honeywell also make them, but they are not sold in the UK.

Siemens and Timguard sell Opentherm, it is definately worth having Opentherm controls
