Getting to Know Your Thermostat Standard Display The current room temperature and time are always part of the standard display. Other displayed data includes heating and air conditioning (Heat/Cool) status, day of the week, schedule period, water heater and appliance status, and the RSVP current price (see Fig. 2). The thermostat display automatically sequences several displays (see Fig. 3).
STANDARD 1 AM 2 HOLD A SERIES OF SCREENS THAT PROVIDE THE PHONE NUMBER TO CALL TO CONTACT YOUR ENERGY UTILITY. TEMPORARY BATTERY LOW INDICATION 1 THIS SCREEN IS ALWAYS PART OF THE DISPLAY SEQUENCE. 2 ONLY APPEARS: WHEN YOUR ENERGY UTILITY SIGNALS IT TO DO SO; DURING A LOSS OF COMMUNICATION, OR A THERMOSTAT FAULT. Fig. 3. Display sequence.
Replacing Thermostat Batteries IMPORTANT Install batteries to maintain the time in the event of a power loss. Although the thermostat has a low battery indicator, replace the batteries once every two years to prevent the thermostat from losing the time during a momentary power loss. Keypad Lift the front cover to see the keypad. From the keypad, you can operate and program the thermostat. To operate the thermostat, press and release the keys.
As the batteries run low, the thermostat display sequence includes an indication of this. The low battery indication appears one to two months before the batteries run out completely. Replace the batteries as soon as possible after the indication appears. You need two AA alkaline batteries (not supplied); non-alkaline batteries do not last as long, and can leak, damaging the thermostat or wall surface. To replace the batteries: 1. Use a coin to carefully remove the battery door (see Fig. 4). 2.
When the light is off, the emergency heat (or auxiliary heat) is off. When the light is on, the emergency heat (or auxiliary heat) is on. Indicator Light This light indicates primarily the emergency heat (or auxiliary heat). It also indicates whether Critical Time-of-Use Pricing is in effect, or is scheduled (see Table 1). Table 1.

Programming Overview User Operations Complete the Personal Programming Charts (Tables 3 through 6) before you program your thermostat. Present Setting Press and release the Present Setting key to return to standard display from any other display. The display first switches to show the current settings. After a few seconds the thermostat returns to the standard display. You can program the thermostat with separate schedules for heat, cool, electric water heater, and one appliance (such as a pool pump).
Overrides An override is a setting used to manually change the setting without affecting the program memory. Hold A hold is a setting used to override the program for an extended period of time. A hold maintains a setting until manually changed. From the standard display, press the Clear key to clear any temperature override in effect. The hold display indicates all items currently set on hold. M15508 M15505 Press and release the Hold key to get to the hold display.
Press Water or Appl keys to toggle the hold status. Water switches between: no hold and hold off. Appl cycles through: no hold, hold on, hold off, and back to no hold. RSVP Price changes to Critical, or the thermostat enters the next scheduled period. The temporary display indicates the items set on temporary. NOTES: — Only items being held appear on the display. — Water cannot be permanently held on, but it can be permanently held off. — With no temperature displayed, no hold exists.
— Press Water or Appl keys to display the temporary display and toggle the water or appliance state. — — — M15509 NOTES: — A temporary cannot clear or replace a hold. — With a hold in effect, an attempt to set a temporary changes the display to the hold display. — Only items being held appear on the display. In spite of period changes, a temporary Water override, by default, lasts for one hour. With no temperature displayed, no temporary exists. Press the Hold key twice to get to the temporary display.
This thermostat uses a recovery process that turns your heating/cooling equipment on or off at the time you program the temperature to change. For example, if you set the thermostat to heat to 72°F at 6:00 AM, the heating equipment comes on at 6:00 AM and begins warming the house to 72°F. If you want the temperature in the house to be 72°F at 6:00 AM, you must set the thermostat to turn on earlier; for example, 5:30.
has time to reach the desired temperature before you get there. NIGHT is the time you usually go to sleep. While you are sleeping, you can save energy by setting the thermostat to control the temperature higher or lower (depending on the season). MORN is the time you get up. Generally, you want the house at a comfortable temperature when you wake up. Set the MORN time earlier than your alarm clock so your home has time to reach the desired temperature. DAY is the time you leave for work or school.
As the cost of energy increases, the thermostat uses your pre-programmed choices to reduce usage by temporarily changing the setpoint; that is, it changes the temperature setting— increasing it for cooling, decreasing it for heating—or turns off the water heater and/or appliance. ture program for every period if your schedule does not require it; for example, if your home is occupied during the day on weekdays, you can program only the MORN and NIGHT times.
NOTE: Before programming the thermostat, remove the clear protective plastic display overlay. CAUTION Equipment Damage Hazard. Use of sharp fingernails or pencil points can damage the keypad beyond repair. Use the ball of your finger or a soft pencil eraser when pressing the keys. Entering Schedule Programming Refer to your Personal Programming Charts and proceed as follows: IMPORTANT The thermostat registers all programming inputs immediately and maintains them until manually changed.
IMPORTANT Because this procedure can affect up to seven days of programming, be careful when making changes with multiple days selected. NOTE: When setting a program time or temperature, the instructions direct you to “Press and hold until the display shows the desired time (or temperature).” This changes the setting quickly in the selected direction. Use this method when the change is large (for example, two hours, or ten degrees).

Troubleshooting IF… THEN… Display does not come on. • There is no power being supplied to the thermostat. Check fuse or circuit breaker. • Check the furnace air filter. A dirty filter will choke the airflow causing safety shutdown; replace or clean, if necessary. Temperature display does not go lower than 45°F or higher than 88°F during programming. • You have reached the thermostat setting limit. The setting range is 45°F to 88°F. Temperature change occurs at the wrong time.
Troubleshooting Guide (continued) IF… THEN… Heating unit does not come on. • Check that the thermostat is set to heat. If it is not, press the Heat/Cool key until the display indicates HEAT. • If the temperature setting is higher than current temperature, and display indicates HEAT, contact your energy utility. • Heat pump thermostats have a built-in five minute time delay for heating. After changing the setting, the thermostat delays before starting the heating to prevent equipment damage.
IF… THEN… Cooling does not come on (continued). • If temperature setting is lower than current temperature and the display indicates COOL, set the system control OFF for ten minutes. After ten minutes, return the system control to cool. If the cooling comes on, the compressor may have reached a safety limit and shut down. If the air conditioner does not come on after ten minutes and the display shows COOL, contact your energy utility. The house is too warm or too cool.
Troubleshooting Guide (continued) IF… THEN… Thermostat current setting • Be aware that it is normal for the current setting and display temperature to differ on occasion. does not match the display • During recovery from setback or setup, setting and display temperature. temperatures may differ during the recovery period. Incorrect room • The thermostat is factory-calibrated and cannot be adjusted. temperature is showing on thermostat display. Thermostat is flashing CALL followed by a phone number.
IF… THEN… Clock gives erroneous reading. • Check to see if display shows low battery, if so replace batteries. • Gulf Power sets the clock and it cannot be adjusted by the customer. If necessary, contact your energy utility. Clock occasionally changes more than one minute at a time. • Your energy utility periodically resets the clock to the correct time. This can change the time more than one minute (see Replacing the Batteries section). Thermostat displays: “bUSY”.
