Hi All, Hoping you can help. I'm having a problem with my RX2C and timer. The reciever will not run the CH. Hot water, no problem. Flick the diverter valve into manual, and it runs both - that's fine, albeit some rads D/S don't heat up (thinking this is a power flush needed as well). The...

Hi All, I am curious to hear if anyone knows if the Vaillant VR33 Module that can be used to convert Vaillant Boilers to support OpenTherm also works together with the Vaillant AroTherm ASHP range? As far as I can understand Vaillant uses a very old protocol (eBus) for communications between...

Hi, I have an Evinox UA10 Room Controller showing an LP message and flickering constantly (like this). I have looked into the user manual but there's no mention of any LP. My first guess was that it stands for "Low Pressure" but the boiler shows a normal pressure. My second guess would be "Low...

Got a small problem with my Vaillant VRC 470f wireless weather compensating heating controller that is used with my Eco Tec Plus 937 boiler. Every now and then (a few to several times a week), the clock on the controller randomly resets its self as if new batteries were put in. This has lead to...
