What have you checked so far.

car 10-07-2010 05:20 AM

I've changed the thermastat

Might want to check to see if the thermostat is getting any voltage. And then check to see if its sending voltage back tot he zone panel. And from there, if the zone motor is getting voltage.

You will have to work back until you find where power is lost

Where would i pick up a control box for furnace:(

beenthere 10-08-2010 04:33 PM

The furnace, generally doesn't provide power to the thermostats in a zoned system.

Or do you have 2 furnaces?

If you don't have a volt meter it's going to be tough to troubleshoot. Pics would help a lot. If you have two thermostats and one furnace, that "control box" sounds a lot like a zone panel. It's a part completely independent of the furnace.

i did use my voltmeter and checked voltage to my second box which i believe controls my second zone mounted on side of furnace.

Take pics and post them.

So we know what these boxes look like.
Also, post brand and model numbers. So we know how they operate.

Ok.

You have a boiler, not a furnace.

Check the terminals of the circulator panel(the one on the side of your boiler) and see it you have voltage at the terminals that the thermostat wires to.

If not. Then check if you have 120 volts to the L1 and L2(hot and common) terminals of that same box.

If you have 120 volts going to it, but no voltage on the thermostat terminals. then the panels transformer is bad.
