So I'm replacing an old analog thermostat with a new digital/programmable one, but I've encountered an issue with wiring.
Most of the wires from the old one had matching colors/codes on the new one, but I have two wires that I'm not sure about.
My white wire was plugged into the W2 connector on the old thermostat and my black wire was plugged into the E connector.
On the new thermostat, the W2 and E connector are one in the same. Do I plug both wires into that connector, does one wire go unused, or does one of them go in one of the other connectors that are open?
Can anyone here help? I haven't been able to find a definitive answer anywhere.
