* Complete warranty details available from your local dealer or at franklinhvacsystems.com. To receive the 10-Year Parts Limited Warranty, the control must be installed in conjunction with a new furnace or air handler containing a communicating system that is compatible with the control and, if that furnace/air handler is a Franklin® brand unit, that furnace/air handler must have been registered online within 60 days of installation of the furnace/air handler. Failure by Quebec or California residents to have registered a Franklin brand furnace/air handler does not diminish their warranty rights.
