I would like to hook up a Honeywell YTH6320R1001 thermostat to a Taco SR503 panel. Can you get 24 volts from the Taco panel or do you need a separate transformer? And, how do you wire it?

From the looks of things the unit only has a 1 amp fuse so pulling 24 volts off it to power a thermostat does not look good. I suggest you contact by email someone in support from taco to get a final answer. Click the link and ask the question. Taco is pretty good at answering.
