Installation

Verify that you have the right thermostat

Make sure that the CT3300 is the right thermostat for your heating/cooling system. Read the compatibility chart below to determine which system you have. If your system is not compatible with the CT3300, the table recommends an alternate Honeywell model. If you are unsure what type of thermostat is right for your system, visit us on the Web at www.honeywell.com/yourhome or call Honeywell Customer Relations at 1-800-468-1502.
