the link you posted, Pat, clearly shows that R (24VAC hot) and C (24VAC common) need to supply power to the thermostat itself. The block seems like an extension of the R C terminals as you describe them, and as the picture shows just as a matter of convenience in wiring. do you read 24VAC between R and C with your meter?
you need to follow Nooner's advice and get a competent tech there,me thinks
It's the hot/common connections that I'm not sure about. The R/C terminals already have wires inserted and these wires go over to a block...which also has screw terminals.
Do I wire directly to the terminals (which have a metal flange partially covering them, as if to prevent you from using them) or to the block(s)?
The directions don't say ANYTHING about the on-board wires, other than don't remove them.

No Problem: its a Lummox with a WR stat
- I only need it to control heat (W), fan (G) and AC (Y)
- The R and C terminals on the unit have red and black wires (respectively) soldered to a block which has 3 terminals on it (see
formatting link
If I connect W/G/Y plus the R wire, the display does not light up - presumably because it needs a full-time connection to T (transformer common)
Has anyone wired up one of these successfully and can I adapt it to my single-stage furnace?
Yup, lots of times
