Red is power
White is Heat
Green is fan
What terminals do you have hooked up to what wires?
so if i touch all three wires together, the heat should come on right? Also since there is no mercury switch how level does it have to be?
If it is not 100% level it should be ok as long as it is close. It shouldn't have too much of a bearing if there is no mercury. Well if you touch the red and white wires together the heat will come on, Green is usually for a fan, i'm not really sure what it is in your application since you don't have a fan. So really green should do nothing, unless you have air conditioning as well, then green would be fan and yellow would be cooling
is there a way to test the thermostat with a continuity tester?
when i touch the red and white the boiler doesn't turn on. but now i touched the green and red and the heat came on so i guess the wires were wrongly coded, on the old thermo the colors were green red white in that order from top to bottom
how could i tell? iam not understanding the question
Sorry, i meant on the old thermostat. You said it was wired green red white top to bottom, what terminals were at the top middle and bottom?
I dug the old thermo out of the trash and the front of it (the actuall thermostat) was paired up to the back plate (the wires from the boiler) like this ? to green red out of wall to white on thermo & white out of wall to yellow on thermo. i guess i should repeat this setup on new thermostat?
your best bet would be to wire it up the same way. They definately did not wire that "correctly" Technically its wired correctly because it worked, but they did not use the standard procedure.
Wire = purpose (suppoced to be)
Green = Power (Red)
Red = Heating (white)
White= Cooling (yellow)
yea i hooked it up the old way and it is working, they had it labled wrong to.
they had it labled blue black and red when the wires were red white and green. its the last time I hire a colored blind one eyed chinaman to do hvac work.
Haha yea, not so good of an idea
If you need anything else please feel free to ask!
