These wires are not used during the installation of your new 3200 thermostat and must be insulated from each other to avoid damaging your electrical circuit. Locate the wires that are connected to the clock terminals marked C or C1. Wrap the wires separately, using electrical tape to insulate the wires. Place the wires where they will not interfere with the operation of the new thermostat. Continue with the installation as instructed on page 4 at step 2e. Six or more wires If your old thermostat has six or more wires (excluding clock wires attached to the C or C1 terminals), your heating/cooling system is most likely a variation of a heat pump or multistage system. Your 3200 thermostat will NOT work with such systems and should be returned to the place of purchase. See the compatibility table on page 2 for information about which programmable thermostat WILL work with your system. Three thermostat wires If you have three wires for heating only and can operate the fan using the fan ON switch, the 3200 thermostat will work with your system. If you have a three-wire heating-only system and cannot operate the fan using the fan ON switch, the 3200 thermostat will probably NOT work with your system.
