Gently tap anchors (provided) into drilled holes until flush with the wall. s Reposition wallplate over holes, pulling wires through wiring opening. Loosely insert two mounting screws into holes. s Level for appearance only; thermostat functions properly even when not level. Tighten mounting screws. LEVEL M611B 17 69-0733--3 STEP 6 Adjust System On-Time, Clock Display, As Required s The thermostat on-time is factory-set for a warm air, gas or oil heating system. If you are installing it on another type of system, the ontime must be adjusted accordingly by setting screws 1A and 1B on the back of the thermostat, using the heating system table in the illustration as a guide. The system on-time should be optimized with the type of system to minimize room temperature swings. Setting the screw out one turn means turning the screw approximately 360° counterclockwise, or about one complete turn. In the unlikely event that you want longer furnace on-time, readjust screws 1A and/or 1B as follows: 18 69-0733--3 First, turn both screws in completely, then adjust for system type: · Hot Water or High Efficiency--Set at the Gravity Air/Water setting (1A--out one turn, 1B--out one turn). · Gas/Oil Warm Air--Set at the Hot Water or High Efficiency setting (1A--leave in, 1B-- out one turn). · Electric Warm Air--Leave at the Gas/ Oil Warm Air setting (1A--leave in, 1B-- leave in). INSTALLATION IMPORTANT: When using a high efficiency furnace such as a 90% or greater AFUE (Average Fuel Utilization Efficiency) unit, leave screw 1A in and screw 1B out one turn. s The thermostat is set to display the time as a 12-hour clock and the temperature in degrees Fahrenheit. If a 24-hour clock (e. g. , military time) or degrees Celsius readings are desired, adjust screws 2A and 2B as necessary using the illustration as a guide. s For an explanation of the Recovery Selection screws (3A), see pages 7 and 8.

This is the correct setting for most systems. If your system is an electric furnace, set the switch to the right (ELEC) position. The ELEC position allows the fan to turn on immediately with the heating or cooling system if the G terminal is connected to a fan relay. NOTE: Either the switch must be set before the batteries are installed, or the left battery must be removed to access the switch.

If unsure about household wiring procedures, call your local heating/air conditioning contractor. Refer to masking tape labels you placed on wires when you removed your old thermostat. s Match the letter of your old thermostat wire with the terminal of the corresponding letter on your new thermostat.
