On a 2 wire heating control, the 2 wires would be connected to the "R" and "W" terminals of the thermostat. The thermostat is simply a switch that routes power to the different connections inside it for different applications. Power comes in on "R" and is sent to "W" when there is a call for heat.

Hi,
maybe a blown fuse if it has one... if not then you blew the transformer...
Check on the circuit board in the furnace or air handler for a fuse...
if there isn't one... then you will need to replace the 24v transformer... they blow very easily...

Amp problems


The main thing that comes to mind is whether you've checked the in-line fuse on the positive wire. Most amp installations are supposed to have a fuse within 1ft of the battery terminal for just such a reason. Next, if you have a voltmeter of some kind (or know someone who does), check to see if you still have 11VDC-14VDC at the power terminals of the amp. If you do, then check the remote turn-on lead (which is supposed to connect to either your head unit or the ignition). If my memory serves, the remote wire should be high (about 12V) when the amp is being told to turn on and low (less than 2V) when it's being told to turn off.

I had the same problem and decided to take a chance and call honeywell customer support. I am shocked, they solved my problem! At least in my situation we found that the blue wire ran the compressor. Instead of hooking up to "blue" on the thermostat, we hooked it up to "white." It works wonderfully now.

Singed wires suggest electrical fault or excessive heat, i personally suggest you have the unit checked out by a professional to ensure your own safety.
