Nothing on the boiler. I used the Honeywell programmer with a built in thermostat.
 
Got it working. The face on the programmer wasn't connecting the pcb board. As I had it screw too tight against the wall. It's clicking off and off now. Great.

Yeah I know. When I remove the back case and put the front back on I heard the signal wire making a click sound to the boiler then it fired up. Thanks to your patience and expert advise now I have a new programmer working.
Thanks again.
