Question about Honeywell Programmable Thermostat Heater
The Rc and Rh should have a jumper wire between them let it in. and hook the red wire to one of them it does not matter which one as they are jumpered. The white wire goes on the "w" terminal and the Blue wire will go on the "G" green terminal to run your fan.
This should get you up and running again!

Here is what you need to do. You're 3 wires R= 24volts hot. White is heat or w. Blue more than likely was used for cooling Y terminal or G for fan. Lay out of a new stat is rc with a jumper wire to rh. rc =r cooling, rh = r heating. Connect your red wire to rh or rc and make sure to leave the jumper in place. Connect the white to W. On a central heat and air, you would normally have 4 terminals as rc and rh count as one.Y= yellow, but you dont have a yellow. So, if you do have cooling on this system, the blue wire will connect to the Y terminal. Green or g is used for fan. Since you have no green wire, i would know that the fan is controled through the blue terminal and will come on in heat or cool. On most heat only systems, they only have 2 wires, red and white. Same connections rc jumpered to rh, and white to w. But since you have a blue wire, I am assuming that you do have cooling also? If so, connect to Y as I said. If no cooling, leave it connected to Y anyway. I have hooked up hundreds of these heating and cooling stats, or heat only and cool only. After you connect the wiring as I have explained, and just to see what they were useing the blue wire for , either Y cooling, or fan G, turn the power back on and set you're stat to come on like you normally did with the old round honeywell.Don't get confused just follow the connections as I said and you will be fine. What I want to determine, is if you have heat only or both and you can let me know. Just connect as I said, very easy. After you turn the unit on and lets say thet the blower fan doesnt come on like it did with the old stat. Then I would know that you have heat only, and you would only have to make one change.ONLY if the fan didnt come on though. This would be the blue wire only. So, after all is connected as I said, and you start it up and the main blower fan never comes on, the only wire you need to move is blue from the Y terminal to G terminal. Try and get back to me to let me know if it is heat only one way or another.This was a long explanation, but I am a perfectionest, and want you to completly get the whole picture. I could have told you in a lot less words, but wanted you to understand in detail.Please let me know though if you are heat only. Good Luck, Sincerely,
Ps, I will be waiting to hear back, Thanks :-)
