Hi all
Hoping to get some help as I can't seem to get the VR33 module working or even powering on. I've had 2 engineers out now and so the cost is starting to add up.
Previously had a vaillant controller (VRC470f) with my boiler. I have now upgraded to a Drayton Wiser but I'm struggling to get the VR33 working so I can't use OpenTherm at the moment.
The VRV470f and it's radio receiver that fits into the front of the boiler were removed. Engineer wired a wallplate for me as I didn't have one before and the Drayton is connected to that which works fine as a smart thermostat.
The VR33 is installed as per the instructions but there is no green LED on it and the boiler doesn't recognise any ebus controller (as well as the Drayton wiser doesn't recognise any opentherm connector.)
I have attached pictures below, the engineer also tried removing 230V RT and leaving it empty but that didn't work and the VR33 still has no power.
Thanks
