I purchased a manual heat-only thermostat, the CT87K. The instructions say that I should label the old wires with the letters provided in the package. Unfortunately, those wires have no letters, and both are white. Does it make any difference which terminals I connect them to? Or how do I tell the difference? Thank you.
