hi
My friend is having trouble changing his stat, he is not sure what the wires are, he has a blue, a brown and a yellow&green, the yg is lighting the bulb on the screwdriver tester and so is the blue, he has 2 terminals on the new stat, one says A one says B the third is COM but that is got a little plastic cover over it which can be broken off if the port is needed.
The wiring for this was done around 1986 and the wire is flex wire.
If he puts the blue in the port A and yg in port b what happens to the brown?? Also would that be the correct wiring method
If anyone has any ideas please post as ive never done anything with stats
thanks
p.s the instructions are available on the link
