Well McLain Goil Oil Boiler - runs, but no heat to one zone

New house. I'm used to the older systems. This one doesn't seem as straightforward so I wanted to be sure it wasn't something stupid before I called a proper tech.

Woke up and noticed the main house was cold. The bedroom was fine though.

There's a box containing some sort of fuses (I guess?) that is emitting a constant beep. A couple of the lights are yellow/orange (see image). I can't find a good troubleshooting doc.

I power cycled the system just for kicks and it did nothing. I checked out the thermostat, but wound up dropping it and i'll be heading to get a new one.

Any initial thoughts on what I should do?

Thanks

This is the only indication of what it might be on the outside. I can pop it open if that's not it.

Looks like the red light is "Priority On", which sounds like if it was off the zones would be independent, so perhaps not the problem?

Well, with the new thermostat I'm getting heat, but the relay is still beeping.

And beeping may be coming from elsewhere. So hard to tell. There's also another control board. Going to diagram this mess, but at least I have heat.

Know of any good resources for a system like this?

Hi, turn the control off and see if you still hear the beep, everything looks normal on that board.

That Argo relay definitely does not beep! If you look around I'll bet you find a Verizon box that needs a battery replaced.

Or a low battery on a smoke detector.
