Do not open mercury cells. If a cell becomes damaged, do not touch any spilled  

mercury. Wearing non-absorbent gloves, take up the spilled mercury and place into  

a container which can be sealed. If a cell becomes damaged, the unit should be  

discarded.

Do not use on circuits exceeding specified voltage. Higher voltage will  

damage control and could cause shock or fire hazard.  

Do not short out terminals on gas valve or primary control to test. Short or  

incorrect wiring will damage thermostat and could cause personal injury  

and/or property damage.

A. Remove base from subbase: Loosen the screws on the base and remove.  

B. Mount switching subbase: Use the screws provided to mount the subbase or  

wallplate to wall (see Fig. 1).  

PREPARATIONS  

1

Assemble tools required: power drill, flat blade screwdriver, wire cutter/stripper, level.  

C. Attach wires to appropriate terminals:  

• For two wire systems (Heat Only or Cool Only). Replace subbase with wall-  

plate. If you have a two-wire Heat Only system, attach one wire to R and one to  

wire W. If you have a two-wire Cool Only system, attach one wire to R and one to  

wire to Y. Tighten any unused terminals securely. (see Fig. 5 and 6).  

Failure to follow and read all instructions carefully before installing or operat-  

ing this control could cause personal injury and/or property damage.  

•

If your system has more than two wires: Use the cross reference chart to  

determine correct wire connections. If you have a four-wire heat/cool system leave  

the factory installed jumper between RC and RH attached (see Fig 2.). If your sys-  

tem has five wires remove the factory installed jumper between RC and RH (see  

Fig 3.).

•

Electric heat or single stage heat pump systems: These thermostats are  

configured from the factory to operate a heat/cool, fossil fuel (gas, oil, etc.) forced  

air system. This is correct 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,  

remove the yellow factory-installed jumper wire from the Y terminal and connect  

it to the A terminal. This will allow the thermostat to energize the fan immediately  

on a call for heat. If you are unsure if the heating system requires the thermostat  

to control the fan, contact a qualified heating and air conditioning service person.  

For single stage heat pump applications (no auxillary heat), install a short jumper  

wire (not included) across terminals W and Y. If the system has a reversing valve  

connection energized in Cooling, attach it to O. If the system has a reversing valve  

connection energized in Heating, attach it to B (see Fig. 4).This thermostat will not  

provide multi-stage heating or cooling.

D. Mount Thermostat Base: Gently push excess wire back into the wall opening  

and plug hole with a fire-resistant material, such as fiberglass insulation to prevent  

drafts from affecting thermostat operation. Mount the thermostat base to the sub-  

base using the three captive screws on the thermostat base. (See Fig. 1) Tighten  

the screws securely. Proceed to Step #5.

CAUTION  

!

To prevent electrical shock and/or equipment damage, disconnect electrical pow-  

er to the system at the main fuse or circuit breaker until installation is complete.  

CAUTION  

!

Before removing wires from old thermostat’s switching subbase, label each wire with  

the terminal designation it was removed from.  

Take care when securing and routing wires so they do not short to adjacent  

terminals or rear of thermostat. Personal injury and/or property damage may  

occur.  

1. Remove OldThermostat: A standard heat/cool thermostat consists of three basic  

parts:  

a. The cover, which may be either a snap-on or hinge type.  

b. The base, which is removed by loosening all captive screws.

White-Rodgers 1F56N-444 Thermostat User Manual Overview

Summary of Contents

• Page 1: If no heat anticipator/indication is showing, do not be concerned; move on to the next step. 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. Mercury must not be discarded in household trash. Thermostat installation and all components of the system shall conform to Class II circuits per the NEC code. Failure to follow and read all instructions carefully before installing or operating this control could cause personal injury and/or property damage. To prevent electrical shock and/or equipment damage, disconnect electrical power to the system at the main fuse or circuit breaker until installation is complete. Before removing wires from old thermostat’s switching subbase, label each wire with the terminal designation it was removed from. The heat anticipator pointer, if adjustable, will be set at one of a series of numbers representing the current rating of the primary control in your furnace. This thermostat will not provide multi-stage heating or cooling.
• Page 2: Set the heat anticipator to match the setting of your old thermostat or the current rating on your main heating control. The heat anticipator is adjustable from 0.15 to 1.2 amps. Adjust the anticipator by rotating the contact arm. Adjustments should not be greater than 1/2 marking at a time. For millivolt operation, rotate the contact arm to Millivolt Link. After power is turned on, use the system switch to select heating or cooling, or to turn the system off. When the fan switch is in the AUTO position, the fan will cycle with the heating or cooling system. For heat only, move the temperature lever to the highest temperature. For cool only, move the temperature lever to the lowest temperature. Temperature range is 50°F to 90°F (10°C to 32°C).
• Page 3: Troubleshooting section outlines common problems and solutions for heating and cooling systems. No heat, no cool, or no fan can be caused by a blown fuse, tripped circuit breaker, or a furnace power switch turned off. To resolve these issues, replace the fuse, reset the breaker, or turn the switch to on. A pilot light not lit or a broken anticipator wire can lead to no heat; re-light the pilot or have a qualified service person check the system. Loose connections to the thermostat or system may also cause heating issues. If the heating system is capable of operation and the no heat condition persists, replace the thermostat. Intermittent heat may require contacting the furnace manufacturer or local service person for assistance. Cooling issues can arise from loose connections, requiring verification of thermostat and system wires. The anticipation setting affects the heating cycle rate; adjustments may be necessary for optimal performance. Thermostat thermometer settings may require adjustment using a standard slotted screwdriver. Calibration of the thermostat setting lever may also be necessary for accurate temperature readings.

• Page 7: Ajuste del anticipador de calor en el valor del termostato viejo o en el valor nominal del control de calefacción principal. El anticipador de calor puede ajustarse de 0.15 a 1.2 A. Ajuste el anticipador girando el brazo de contacto. Si no está seguro del valor a ajustar, consulte al fabricante del calefactor. Para el funcionamiento milivoltio, gire el brazo de contacto a Conexión de milivoltio. Una vez encendida la alimentación, utilice el interruptor del sistema para seleccionar calefacción o enfriamiento. Cuando el interruptor del ventilador está en la posición AUTO, el ventilador se encenderá y apagará con el sistema. Para sólo calor, mueva la palanca de temperatura a la temperatura más alta. Rango de temperatura de referencia es de 50°F a 90°F (10°C a 32°C). Rango de humedad operativa es de 0 a 90 % sin condensación.
• Page 8: Cómo retirar el termostato viejo. Este producto no contiene mercurio. No abra las celdas de mercurio. El mercurio no debe desecharse con los residuos domésticos. La instalación del termostato debe ajustarse a las normas del código NEC. Retire la base de la subbase. Conecte los cables a las terminales correspondientes. Para evitar descargas eléctricas, desconecte la alimentación eléctrica. Identifique cada cable con la designación de la terminal. Un termostato de calor/frío estándar consta de tres partes básicas.
