controls heating at 68°F (20°C) and cooling at 78°F (26°C), 24 hours a day. Also, you do not need to enter a time and temperature program for all periods if your schedule does not require it. For example, a house that is occupied during weekdays would not require programs for LEAVE and RETURN. Select RETURN if you want the house at a comfortable temperature for activities before bedtime.

Setting Fan and System Switches First set the fan switch. Then set the system switch. Auto On AUTO: Normal setting for most homes. A single-speed fan turns on automatically with the air conditioner or furnace. A two-speed fan usually runs on high with the air conditioner and runs on low with the furnace. COOL: The thermostat controls your air conditioning system. Cool Off Heat OFF: Both the heating and air conditioning systems are off.
Changing Batteries After the batteries are completely dead, the bAt Lo indicator disappears, leaving the display completely blank and the heating and/or cooling system not operating. • Use two AA alkaline batteries; nonalkaline batteries do not last as long. • Make sure the thermostat is set to the OFF position. • Use a coin to remove the battery door. IMPORTANT Batteries are required for programming and operation of the thermostat and heating/cooling system.
INSTALL TWO AA ALKALINE BATTERIES AS SHOWN To remove batteries, press down on the left ends of the batteries. If you insert new batteries within 20 to 30 seconds of removing the old ones, the thermostat does not require reprogramming. However, if the display is blank, the batteries are dead or incorrectly installed and the thermostat requires reprogramming. • Install the fresh batteries, as shown, making sure positive and negative terminals are oriented correctly. • Replace the battery door.
