I have an RDJ10RF unit, which I believe is set up correctly.

Customer Question

I have an RDJ10RF unit, which I believe is set up correctly. I've watched the videos for temperature set up and communication issues.
My problem is that the boiler won't fire up. It does so on demand for hot water. The room temperature is lower than that set on the thermostat.
The water pressure is in the green.
Is there anything that I am missing?

Does the boiler fire if you press the button on the receiver?
