T8131C Programmable Thermostat OWNER'S GUIDE Weekday/Weekend Programmable Heat and/or Cool Thermostat and Mounting Plate 1 69-0812-2 69-0812--2 Welcome to the world of comfort and energy savings with your new Honeywell programmable thermostat. Your new T8131 Thermostat is designed to provide you with reliable, precise temperature control. By following the simple programming instructions in this manual, your thermostat will automatically control the temperature in your home. Temperature control saves energy and allows you to awake (or return home) to a comfortable level of heating or air conditioning. Direct questions concerning the operation of this thermostat to Honeywell Customer Assistance at 1-800-468-1502, Monday-Friday, 7:00 a.m.-5:30 p.m., Central time. 2 69-0812--2 Table of Contents Page Programming Thermostat ............................................................................................................... 4 Program Schedule .......................................................................................................................... 6 T8131C Programming Guide .......................................................................................................... 8 Setting Fan and System Switches .................................................................................................. 12 Installing Batteries ........................................................................................................................... 13 Troubleshooting Guide .................................................................................................................... 15 Limited One-Year Warranty .................................................................................... Inside Back Cover 3 69-0812--2 Programming Thermostat NOTE: When batteries are installed, your T8131 Thermostat can be programmed in your hand (armchair programming), or when it is mounted on the wall. Batteries are not required for normal thermostat operation; however, installed batteries are recommended to retain your personal temperature program in memory if ac power is lost. See Installing Batteries section. When you program the thermostat, set one schedule for weekdays and another for weekends, because your temperature requirements probably vary. (During weekends, only the WAKE and SLEEP time periods are available.) Use the personal Program Schedule for planning your program schedule of time and temperature settings for various times of the day. Four time periods are available during weekdays --WAKE, LEAVE, RETURN, and SLEEP. View these periods individually on the display when you press the Set Schedule key. Select WAKE if you want the house at a comfortable temperature when you get up, while you get ready for work or school. When deciding what time to set for your WAKE period, include extra lead time, depending on the outside temperature and your furnace response time, to give the furnace a head start to heat the house before you get up. (This will be a higher temperature during heating season, or a lower temperature during cooling season.) 4 69-0812--2 Select LEAVE if you want an energy-saving temperature while you are away at work or school. (This will be a lower temperature during heating season, or a higher temperature during cooling season.) Select RETURN if you want the house at a comfortable temperature for activities before bedtime. When deciding what time to set for your RETURN period, include extra lead time, depending on the outside temperature and your furnace response time, to give the furnace a head start to heat the house before you arrive home. (Again, higher for heating or lower for cooling.) Select SLEEP if you want an energy-saving temperature while you are sleeping. (For more comfortable sleeping, some people choose not to raise the cool temperature during the night.) 5 Fill in the times and temperatures you desire for weekdays and weekends. If you decide not to program the thermostat, it automatically 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. When pressing the keys, use the ball of your finger or a soft pencil eraser. NOTE: Using sharp fingernails or pencil points can damage the keypad. If you make an error at any time during programming, just press the Run Program key, and continue again at the last step. 69-0812--2 Program Schedule HEATING PROGRAM SCHEDULE Weekdays WAKE 1 LEAVE RETURN 1 SLEEP Weekends WAKE 1 SLEEP 1 Start Time Heating Temperature 2 WAKE and RETURN start times should include extra lead time, based on outside temperature and furnace response time, to give your furnace a head start to heat the house. 2 The temperatures cannot be set any higher than 88°F (31°C) or any lower than 45°F (7°C). 6 69-0812--2 COOLING PROGRAM SCHEDULE Weekdays WAKE 1 LEAVE RETURN 1 SLEEP Weekends WAKE 1 SLEEP 1 Start Time Heating Temperature 2 WAKE and RETURN start times should include extra lead time, based on outside temperature and furnace response time, to give your furnace a head start to heat the house. 2 The temperatures cannot be set any higher than 88°F (31°C) or any lower than 45°F (7°C).
