Based on the schematics, it looks like Astuff is correct about the terminals. You can always confirm "W/Z" is the common by checking with a voltmeter that there is 24V across "Tv" and "W/Z".

Just to add. the cheaper non EXP version of the taco I listed above should work; at first I didn't think it had a transformer built in but I believe it does. It is just the SR501-4.

I second all of PJ's comments. Check for a loose fuse or connection at ac input. Everything else is wired up properly now.

Just to confirm you have just one heating zone, right?

If so, two alternative approaches that won't require you messing around with the aquastat:

Thanks, maarkr and PJmax. Leaving it open seems to be the more common opinion. It seems that while cooling the attic is less ideal, decreasing airflow is much worse. Eitherway, both the second floor...

the "R" to the thermostat should make 24V with the common, "C". That will power your stat. Unfortunately, they typically don't advertise a 24V "C" terminal on the aquastat because they aren't...
