THE OPTIMUM COMFORT AND ENERGY SAVINGS SOLUTION ■ This thermostat is actually a small but powerful computer. When calculating the exact time to turn on your furnace or air conditioner, it considers (1) air temperature, (2) the temperature of the wall and (3) when you want the comfort temperature established. ■ During programmed recovery, the thermostat gradually increases the control temperature and turns the equipment on and off several times to save energy by avoiding overshooting the comfort temperature.

Recovery Setting Your thermostat includes a screw on the back marked 3A, allowing for the Programmed Recovery/conventional recovery choice. Your thermostat was shipped from the factory with the screw positioned for Programmed Recovery. Your installer may have left the screw in this position, or may have changed it to conventional recovery. Before programming, you must know the recovery method selected for your thermostat.

Programming Your Thermostat The thermostat can be programmed in your hand before it is installed or after it is on the wall if you make sure the batteries are installed. If you need to install or replace the batteries, refer to the Maintaining Your Thermostat section. ECON D'ENERGIE SYSTEME TEMPERATURE ACTIVER PROGRAMME 5-1-1 PROGRAMMING The Program Schedule chart can be helpful for planning your program schedule of time and temperature settings for various times of the day.

Cooling Program The program times are the same for both heating and cooling. Program only the cooling temperatures if you have already programmed for heating. To set times as you program the cooling temperatures, use the AVANCER and RECULER keys. But if you change the times for cooling, you are also changing them for heating. 1. Move the system switch to the REFROID. position, following the same instructions as for the heating program. 2. After programming, adjust fan and system switches as desired. 3.

Maintaining Your Thermostat ■ Replace the thermostat on the wall. See page 15. ■ Reprogram, if necessary. REPLACING THE BATTERIES Your thermostat uses three AAA alkaline batteries. We recommend Energizer® batteries. The display will flash “BAT” when the batteries get low. Unless the display is blank (indicating the batteries are dead) when you start, you won’t have to reprogram the thermostat if you can insert the new batteries within 20 to 30 seconds of taking out the old ones.

Setback Reducing the temperature in the house for a set period every day in winter for energy savings. The lower temperature is the energy saving temperature. RÉVEIL— The time period when you want the house at a comfortable temperature while the family gets up and gets ready to leave for work or school. This is the only period that must contain a time and temperature. Setup Raising the temperature in the house for a set period every day in summer for energy savings.

Troubleshooting Guide IF… Display will not come on. THEN… ■ Check that heat or cool system power is on. If you use batteries, replace with fresh ones. ■ Make sure thermostat is correctly mounted on base. Display flashes during programming. ■ You have reached the temperature setting limit. The setting range is 7° C to 31° C. The cool temperature setting must be a least 2° C above the heat temperature setting. Display flashes during operation. ■ Programming has been lost because of a power outage.
