It is recommended that as you read, understand and complete each step, you check  it off with pencil or pen. Check thermostat suitability for your home's system by reviewing the ratings listed above. Make certain that your heating system is working, especially if it has been inoperative for a length of time. If the system does not work, contact your local electrician for assistance. WARNING This thermostat is a line voltage control (120 Volts to 240 Volts.) Do not install it if you are not completely familiar with house wiring. If handled improperly, there can be risk of a 120 Volt to 240 Volt electric shock hazard, which may cause serious injury or death. Carefully unpack your new thermostat. To avoid damage to the sensing element, do NOT remove the thermostat cover until wiring has been completed. Save packages of screws, instructions, receipt and proof-of-purchase. 2 THERMOSTAT MOUNTING DIMENSIONS FRONT VIEW 80 • 70 • 60 • 50 • ˚F SIDE VIEW 1-3/4 (48) 3/4 (19) 1/2 (13) 4-3/8 (111) 2-1/8 (54) 3-1/4 (83) 2-7/8 (73) 1-1/2 (39) 1/2 (13) M5795A 3 REMOVE OLD THERMOSTAT WARNING Begin by turning off power to the heating circuit at the main service panel. Remove cover of old thermostat-cover normally snaps off when pulled firmly from the bottom. If it resists, check for a screw that locks the cover. Loosen screws holding thermostat base to outlet box and lift away. Disconnect wires from old thermostat. As you disconnect each wire, tape the end and label it with the letter of the terminal designation to make reconnection to new thermostat easier. Check the old insulation for cracks, nicks or fraying, and apply high quality plastic tape where necessary for adequate insulation. Retain the old thermostat for reference purposes and until your new thermostat is functioning smoothly. S.M. • Rev. 11-94 • ©Honeywell Inc. 1994 • Form Number 69-0829-1
