I went to install a programable thermostat in my dads house the other day and came into a problem. He has baseboard heating. So I pulled the thermostat off the wall and looked at the back of it and it was connected with 12/2 wire. So I went to test the voltage thinking that it would be 120 but it was 24 volts.
So I go into the basement to the boiler and the wire coming off the boiler is 18/2 wire and then about 10 feet down the line they splice the 18/2 wire to 12/2 wire.
Its been like this for a long time and he never knew that it was spliced to bigger wire.
So what I was going to do was just splice it again in the box that the thermostat is in to 18/2 wire.
But the problem i was having with that is the old thermostat wires are on the terminals labeled 1 and 2 so I wasnt sure what the would cross reference with the new thermostat.
Any suggestions?
Thanks
