2441TH Thermostat Does Not Power

Figured it out. The furnace had a terminal labeled "c". Connected the blue wire to that and everything works great.

gratz!

can you add some details about it? it would be perfect, if you provide a picture. I'm not sure, what I need to do with my system. the only thing I've found out: the wires from the thermostat go directly into the furnace (CONQUEST 90 series GLUA/GLDH):

so definitely I will need to open it and to do something inside.

so, do I understand correctly?

I need to connect this blue wire to the "C"?

From the furnace manual:

The significant detail was mentioned. Terminal C is the standard designation for the common wire. Here's a list:

R 24VAC
C Common
W/W1 First stage heating
W2 Second stage heating
Y/Y1 First stage cooling
Y2 Second stage heating
G Fan
O/B Heat pump reverse valve

Some HVAC systems may have a 3rd stage heating and/or cooling.

I understand. I just want to make sure I got everything properly.

so I'm going to connect the blue wire to the "C" terminal. I'll let you know, if it's a success.

thanks very much to all! especially to stusviews and jesn. it works!

I've connected the blue wire to "C" terminal on the furnace panel, and voila!
