3. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat.
4. Disconnect the wires from old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL.
5. Install new thermostat using the following procedures.

ATTENTION!

This product does not contain mercury. However, this product may replace a unit which contains mercury.

Do not open mercury cells. If a cell becomes damaged, do not touch any spilled mercury. Wearing nonabsorbent gloves, take up the spilled mercury with sand or other absorbent material and place into a container which can be sealed. If a cell becomes damaged, the unit should be discarded.

Mercury must not be discarded in household trash. When the unit this product is replacing is to be discarded, place in a suitable container. Refer to www.white-rodgers.com for location to send product containing mercury.

ELECTRIC HEAT OR SINGLE-STAGE HEAT PUMP SYSTEMS

This thermostat is configured from the factory to operate a heat/cool, fossil fuel (gas, oil, etc.), forced air system. It is configured correctly for any system that DOES NOT require the thermostat to energize the fan on a call for heat. If your system is an electric heat or heat-pump system that REQUIRES the thermostat to turn on the fan on a call for heat, locate the GAS/ELECTRIC switch on the back of the thermostat and switch it to the ELECTRIC position. This will allow the thermostat to energize the fan immediately on a call for heat. If you are unsure if the heating/cooling system requires the thermostat to control the fan, contact a qualified heating and air conditioning service person.

ATTACH THERMOSTAT BASE TO WALL

1. Remove the packing material from the thermostat. Gently pull the cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit. If necessary, move the electric heat switch (see ELECTRIC HEAT SYSTEMS, above).
2. Connect wires beneath terminal screws on base using appropriate wiring schematic (see figures 2 through 7).
3. Place base over hole in wall and mark mounting hole locations on wall using base as a template.
4. Move base out of the way. Drill mounting holes.
5. Fasten base loosely to wall, as shown in Figure 1, using two mounting screws. Place a level against bottom of base, adjust until level, and then tighten screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure subbase.

Figure 1. Thermostat Base

BATTERY LOCATION

2 "AA" alkaline batteries are included in the thermostat at the factory with a battery tag to prevent power drainage. You must remove the battery tag to engage the batteries.

If "LO BATTERY" is displayed, the batteries are low and should be replaced. For best results, replace all batteries with new premium brand alkaline batteries such as Duracell® or Energizer®. To replace batteries, install the batteries along the top of the base (see Fig. 1). The batteries must be installed with the positive (+) end to the left.

HYDRONIC (HOT WATER OR STEAM) HEATING SYSTEMS

This thermostat is set to operate properly with a forced-air heating system. If you have a hydronic heating system (a system that heats with hot water or steam), you must set the thermostat to operate properly with your system. Change the second option in the configuration menu to SL (see CONFIGURATION MENU, page 4).

CHECK THERMOSTAT OPERATION

If at any time during testing your system does not operate properly, contact a qualified service person.

Turn on power to the system.

Fan Operation

If your system does not have a G terminal connection, skip to Heating System.

1. Move FAN switch to ON position. The blower should begin to operate.
2. Move FAN switch to AUTO position. The blower should stop immediately.

Heating System

1. Move SYSTEM switch to HEAT position. If the heating system has a standing pilot, be sure to light it.
2. Press [Up Arrow] to adjust thermostat setting above room temperature. The heating system should begin to operate.
3. Press [Down Arrow] to adjust temperature setting below room temperature. The heating system should stop operating.

Cooling System

To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system.

1. Move SYSTEM switch to COOL position.
2. Press [Down Arrow] to adjust thermostat setting below room temperature. The blower should come on immediately on high speed, followed by cold air circulation.
3. Press [Up Arrow] to adjust temperature setting above room temperature. The cooling system should stop operating.

OPERATION

Before you begin using 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 (see fig. 8)

• (1) Raises temperature setting.
• (2) Lowers temperature setting.
• (3) FAN switch (ON, AUTO).
• (4) SYSTEM switch (COOL, OFF, HEAT).

The Display

• (5) Flame 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.
• (6) Displays current temperature.
• (7) Displays "FILTER" when the system has run for the selected filter time period as a reminder to change or clean your air filter.
• (8) Displays set point temperature (this is blank when SYSTEM switch is in the OFF position).
• (9) Displays "BATTERY" and "LO" in the current temperature location when the 2 "AA" batteries are low and should be replaced.

CONFIGURATION MENU

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

Move SYSTEM switch to the OFF position, then press [Up Arrow] and [Down Arrow] at the same time to enter the configuration menu. The display will show the first item in the configuration menu.

Press [Up Arrow] and [Down Arrow] to change to the next menu item. To exit the menu, move the SYSTEM switch to HEAT or COOL. If no keys are pressed within fifteen minutes, the thermostat will exit the configuration menu.

Configuration Menu

* Press [Up Arrow] and [Down Arrow] to advance to next item

Comments on Configuration Options:

• 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 normally 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 approximately 1.5°F.
• Select Display Backlight (d-L OFF or ON): The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will keep the light on for a short period of time after any key is pressed. Selecting OFF will keep the light off.
• Select filter replacement run time: The thermostat will display "FILTER" after the selected 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 "FILTER" is displayed, you can clear it by pressing [Up Arrow] and [Down Arrow] at the same time. This resets the timer and starts counting the hours until the next filter change.
• Select Compressor Lockout (LOC OFF or ON): Selecting LOC ON will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. It will also wait 5 minutes minimum between cooling cycles. This is intended to help protect the compressor from short cycling. Some newer compressors already have a time delay built in and do not require this feature. Your compressor manufacturer can tell you if the feature is already present in their system. When the compressor time delay occurs it will flash the (snowflake icon ❄️) for about five minutes then turn on the compressor.
• Select Temperature Display Adjustment (4 LO to 4 HI): Allows you to adjust the room temperature display 4° higher or lower. Your thermostat was accurately calibrated at the factory but you have the option to change the display temperature to match your previous thermostat.
• Select Temperature Display (°F or °C): Changes the display readout to Celsius or Fahrenheit as required.

OPERATING FEATURES

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.

• SIMULTANEOUS HEATING/COOLING SETPOINT STORAGE: You can enter both your heating and cooling set points at the same time. There is no need to change the thermostat at the beginning of each season.
• CONFIGURATION MENU: Allows you to customize certain thermostat options.

SETTING THE THERMOSTAT

This thermostat is very easy to operate. Set the SYSTEM switch to either HEAT or COOL then press [Up Arrow] or [Down Arrow] until the temperature you want to maintain is shown on the right side of the display. If you want to turn the system off, just move the SYSTEM switch to OFF.

The FAN switch controls the fan operation. When the FAN switch is set to AUTO, the fan will cycle with the furnace or air conditioner. When the FAN switch is set to ON, the fan will run continuously, regardless of SYSTEM switch position.

TROUBLESHOOTING

No Heating

With the SYSTEM switch set to HEAT, when the setpoint temperature is raised or lowered past the room temperature, the thermostat will make a soft click sound. Usually, the sound indicates the thermostat is operating correctly. If the system does not come on, check the system or contact your heating/ cooling service person. If the thermostat does not click try the Reset Operation listed below.

No Cooling

Same procedure as heating except set SYSTEM switch to COOL. There can be up to a 5 minute compressor lock-out time delay before the thermostat clicks in COOL.

Blank Display

A blank digital display usually indicates the thermostat has received a voltage spike, static discharge or requires new batteries. If the display remains blank after replacing the batteries, see Reset Operation below.

Reset Operation

If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation you can reset the thermostat by pressing [Up Arrow], [Down Arrow] and move the SYSTEM switch from OFF to HEAT at the same time. This also resets the factory defaults to the configuration menu. If the thermostat has power, has been reset and still does not function correctly contact your heating/cooling service person or place of purchase.

Menú de configuración

* Presione [Up Arrow] y [Down Arrow] para pasar a la siguiente opción del menú.

Comentarios sobre las Opciones de Configuración:

• Seleccione FA o SL (rápida o lenta) para la velocidad del ciclo de calefacción: La configuración FA suele utilizarse para sistemas de calefacción de gas, aceite o eléctricos. La configuración SL produce un ciclo de calefacción más largo que lo normal para sistemas de agua caliente o vapor (hidrónicos). Ambas configuraciones producen un control de temperatura sumamente exacto y pueden ajustarse según su preferencia personal. La configuración FA apaga y enciende el sistema debajo de 1°F y la configuración SL lo hace a aproximadamente 1.5°F.
• Seleccione luz de fondo de pantalla (d-L OFF [desactivada] u ON [activada]): La luz de fondo mejora el contraste de la pantalla en condiciones de poca luz. Si selecciona backlight ON, la luz se mantendrá encendida durante un breve tiempo después de presionar cualquier botón. Si selecciona OFF, la luz se mantendrá apagada.
• Seleccione tiempo de ejecución de reemplazo de filtro: El termostato mostrará "FILTER" después del tiempo de funcionamiento seleccionado. El propósito de este mensaje es recordarle que cambie o limpie el filtro de aire. El tiempo puede ajustarse desde 0 hasta 1950 horas en incrementos de 50 horas. Si elige 000, se cancelará esta función. Cuando aparece "FILTER", puede borrarlo presionando [Up Arrow] y [Down Arrow] al mismo tiempo. De esta manera volverá a cero el reloj y se comenzarán a contar las horas que faltan hasta el siguiente cambio de filtro.
• Seleccione bloqueo del compresor (LOC OFF [desactivado] u ON [activado]): Si selecciona LOC ON el termostato esperará 5 minutos para encender el compresor si el sistema de calefacción y refrigeración deja de recibir alimentación eléctrica. También esperará 5 minutos como mínimo entre ciclos de refrigeración para evitar que el compresor realice ciclos de encendido y apagado cortos. Algunos compresores más nuevos ya tienen incorporada una demora de tiempo y no requieren esta función. Consulte al fabricante de su compresor para saber si su modelo incluye con esta función. Cuando se produce la demora de tiempo del compresor, el (icono del copo de nieve ❄️) se pone en intermitente durante unos cinco minutos y luego enciende el compresor.
• Seleccione ajuste de la pantalla de temperatura (4LO [más abajo] a 4HI [más arriba]): Le permite ajustar la pantalla de temperatura ambiente 4° más arriba o más abajo. El termostato viene calibrado con precisión de fábrica pero usted tiene la opción de cambiar el valor de temperatura que aparece en la pantalla para que coincida con el de su termostato anterior.
• Seleccione visualización de temperatura (°F o °C): Cambia la unidad en que aparece la temperatura en la pantalla a grados Celsius o Fahrenheit según su preferencia.

FUNCIONES DEL TERMOSTATO

Ahora que está familiarizado con los botones del termostato y la pantalla, lea la siguiente información para conocer las diferentes funciones del termostato.

• ALMACENAMIENTO SIMULTÁNEO DE TEMPERATURAS DE REFERENCIA DE CALEFACCIÓN/REFRIGERACIÓN: Puede ingresar sus temperaturas de referencia de calefacción y refrigeración al mismo tiempo. No es necesario realizar modificaciones en el termostato al comienzo de cada estación.
• MENÚ DE CONFIGURACIÓN: Le permite personalizar ciertas opciones del termostato.

AJUSTE DEL TERMOSTATO

Este termostato es muy sencillo de operar. Ajuste el interruptor SYSTEM en HEAT o COOL y luego presione [Up Arrow] o [Down Arrow] hasta que la temperatura que desea mantener aparezca a la derecha de la pantalla. Si desea apagar el sistema, simplemente mueva el interruptor SYSTEM a la posición OFF.

El interruptor FAN controla el funcionamiento del ventilador. Cuando el interruptor FAN se coloca en AUTO, el ventilador se encenderá y se apagará con la caldera o el aire acondicionado. Cuando el interruptor FAN está ajustado en ON, el ventilador funcionará de manera ininterrumpida, independientemente de la posición del interruptor SYSTEM.

SOLUCIÓN DE PROBLEMAS

El sistema no calienta

Con el interruptor SYSTEM ajustado en HEAT, cuando la temperatura de referencia se sube o se baja por encima o debajo de la temperatura ambiente, el termostato emitirá un chasquido suave. Por lo general, el sonido indica que el termostato está funcionando correctamente. Si el sistema no se enciende, verifique el sistema o póngase en contacto con su servicio técnico de calefacción/refrigeración. Si el termostato no emite un chasquido, siga el procedimiento indicado en la sección Operación de reajuste a continuación.

El sistema no enfría

Siga el mismo procedimiento que para calefacción colocando el interruptor SYSTEM en COOL. Es posible que haya una demora del bloqueo del compresor de hasta 5 minutos antes de que el termostato se active en COOL.

La pantalla está en blanco

Por lo general, una pantalla digital en blanco indica que el termostato ha recibido un pico de voltaje o una descarga estática o que es necesario cambiar las pilas. Si la pantalla permanece en blanco después de cambiar las pilas, vea la sección Operación de reajuste a continuación.

Operación de reajuste

Si un pico de voltaje o una descarga estática pone en blanco la pantalla o hace que el termostato funcione de manera errática, puede reajustarlo presionando [Up Arrow] y [Down Arrow] y moviendo el interruptor SYSTEM de OFF a HEAT al mismo tiempo. De esta manera, también reajustará los valores predeterminados de fábrica según el menú de configuración. Si el termostato tiene alimentación y se ha reajustado pero aún no funciona correctamente, póngase en contacto con su servicio técnico de calefacción/refrigeración o con el lugar donde realizó la compra.
