White Rodgers 1F87-251 Operation, Configuration Menu, Thermostat Buttons and Switches, Display

OPERATION

Before you begin programming your thermostat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons. Your thermostat consists of two parts: the thermostat cover and the base. To remove the cover, pull it straight out from the base. To replace the cover, line up the cover with the base and press until the cover snaps onto the base.

The Thermostat Buttons and Switches

1Raises temperature setting.

2Lowers temperature setting.

3 TIME button.

The Display

9 Indicates day of the week.

10Flame icon () is displayed when the SYSTEM switch is in the HEAT position. Snowflake icon ()is displayed (non- flashing) when the SYSTEM switch is in the COOL position. Snowflake is displayed (flashing) if the thermostat is in lockout mode to prevent the compressor from cycling too quickly.

11Displays "LO BATT" when the 2 "AA" batteries are low and should be replaced. Nothing else will be displayed.

12Alternately displays current time and temperature. Displays "LO" in the minutes field when batteries are low.

13The word "HOLD" is displayed when the thermostat is in the HOLD mode.

14Displays currently programmed set temperature (this is blank when SYSTEM switch is in the OFF position).

15Displays "FLTR" when the system has run for the pro- grammed filter time period as a reminder to change or clean your air filter.

CONFIGURATION MENU

The configuration menu allows you to set certain thermostat operating characteristics to your system or personal require- ments.

Press RUN to make sure the thermostat is in the run program mode, then press PRGM and RUN at the same time to enter the configuration menu. The display will show the first item in the configuration menu.

The configuration menu table summarizes the configuration options. An explanation of each option follows.

Press HOLD to change to the next menu item or press TIME to go backwards to the previous item in the menu. To exit the menu and return to the program operation, press RUN. If no keys are pressed within fifteen minutes, the thermostat will revert to normal operation.

1)Select FA or SL (Fast or Slow) Heating Cycle Rate - The FA setting is frequently used for gas, oil or electric heat. The SL setting produces a longer heating cycle which is nor- mally for hot water or steam (hydronic) systems. Both settings produce very accurate temperature control and can be set to your personal preference. FA cycles the system just under 1°F and the SL setting cycles at approxi- mately 1.5°F.

2)Select backlit display - The display backlight improves display contrast in low lighting conditions. Selecting back- light ON will keep the light on for a short period of time after any key is pressed. Selecting OFF will keep the light off.

3)Select Energy Management Recovery OFF or ON - Energy Management Recovery (EMR) causes the thermo- stat to start heating or cooling early to make the building temperature reach the program setpoint at the time you specify. Heating will start 5 minutes early for every 1° of temperature required to reach setpoint.

Example: You select EMR and have your heating pro- grammed to 65° at night and 70° at 7 AM. If the building temperature is 65°the difference between 65°and 70°is 5°. Allowing 5 minutes per degree the thermostat setpoint will change to 70° at 6:35 AM. Cooling allows more time per degree because it takes longer to reach temperature.

4)Select filter replacement run time - The thermostat will display "FLTR" after a set time of operation. This is a reminder to change or clean your air filter. This time can be set from 0 to 1950 hours in 50 hour increments. A selection of 000 will cancel this feature. When "FLTR" is displayed, you can clear it by pressing HOLD and RUN at the same time. This resets the timer and starts counting the hours until the next filter change. Changing the time in the menu also resets the timer.
