I was painting my wall and I decided to remove my thermostat off the mounting plate, after I finish I put it back but it didn't work anymore, so I check the wires and noticed a black wire that was loose, all the other wires were in place, so I tried to tight those but a think I accidentally touch the red an blue wire together, so I went to turn the power switch off an d recheck, everything looks fine but when I turn the power switch back on the thermostat have no power, what can I do since I don't know where the black wire come from and whether I short circuit something, this is the diagram on the mounting plate, green G: blue C; red R; yellow Y; white L and W2; orange O; and W1,E,B don't have wires.
What should I do?:confused:

Find the cause of the power interruption. Check the transformer to see if it is working supplying 24 volts.

If you are lucky, you blew the fuse on the control board. If you need help finding the fuse, see https://www.askmehelpdesk.com/heatin...ons-58313.html
