Hi there,
I'm switching my thermostat for a newer digital one, though when I took out the old thermostat, there were only 2 black wires with white stripes on them.
The new thermostat calls for an RH wire and a W wire, but I have no way of distinguishing the two apart.
How can I tell which wire is which?
Thanks for the help.
*EDIT*
Would it be wise to get myself a Volt Ohm Meter and check to see which wire is sending 24 volts?
