hello. i've got no power to my thermostat. i've got a dual climate zone in my house, and the upstairs unit has no power. i attemped to replace thermostat with a programmable one today, and mid-way through the job, found out i couldn't use the new one, so i decided to put the old one back on. wired it back based on the diagram i jotted down before i took the old one off. blue going to L, green going to G, black going to c, red to r, orange to o, yellow to y, and a jump bar between y and W1, and white going to E and W2. now, no power and i've checked all circuits and everything is fine. any ideas??? i need some major help here. thanks!
