INTRODUCTION

Bryant’s Legacyt Series programmable thermostats are wall-mounted, low-voltage thermostats which maintain room temperature by controlling the operation of a heating and/or air conditioning system. Both heat pump and air conditioner models are available, each in programmable and non-programmable versions. A variety of features are provided including battery operation, separate heating and cooling setpoints, auto changeover, keypad lockout, backlighting, and built-in installer test. Programming features include 7-day (all days the same) and 5/2 (Mon-Fri and Sat-Sun) with 2 or 4 periods per day.

This Installation Instruction covers installation, configuration, and start-up of all four versions of the Legacy Series line of thermostats. For operational details, consult the Owner’s Manual for the specific thermostat you are installing.
