Call the card companie and see if you have funds on the card. Sometimes I think I do and then I didn't realize the fees ate it up. Or they could have shut off your card.

The color code for thermostat wiring is as follows.
The "R" terminal is power into the stat from the boiler control transformer. Normally 24 volts. The "Y" terminal is for cooling. Normally left blank for a boiler. The "W" terminal is for heat. This one used to start the heating cycle.The "G" terminal is for fan operation. Probably not used for a boiler. Check the boiler terminal board for these functions and write down the wire color on each one. Match the boiler colors to the right function on the stat. If you need more than this, let me know.

You do realise that the itme you are asking about is not a computer motherboard, don't you? It is a heating system controller.
