White Rodgers 1F56N-444 MOUNTING AND WIRING

  1. Remove base from subbase: Loosen the screws on the base and remove.
  2. Mount switching subbase: Use the screws provided to mount the subbase or wallplate to wall (see Fig. 1).
  3. Attach wires to appropriate terminals:
    • For two wire systems (Heat Only or Cool Only). Replace subbase with wallplate. 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).
    • 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 system 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 heatpump 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.
  4. 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 subbase using the three captive screws on the thermostat base. (See Fig.Thermostat Features) Tighten the screws securely. Proceed to Step #5.

White Rodgers 1F56N-444 SET HEAT ANTICIPATOR

Set anticipator to match the setting of your old thermostat you noted in Step 3, or, the anticipator should be set to match the current rating stamped 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 (see fig. 5). The anticipator setting is indicated by the numbers on the base that the pointer points to. If you are unsure where to set the anticipator contact the heater manufacturer for a recommended setting. Move the pointer counterclockwise to lengthen heating system cycles; move clockwise to shorten heating cycles. Adjustments should not be greater than 1/2 marking at a time. For millivolt operation, rotate contact arm to Millivolt Link. Snap on Cover: Carefully align the cover with the base and snap the cover onto the base.

White Rodgers 1F56N-444 NEW THERMOSTAT OPERATION

Thermostat on Subbase. After power is turned on, use the system switch to select either heating or cooling, or to turn the heating/cooling system off. Use the fan switch to control fan operation. When the fan switch is in the AUTO position, the fan will cycle with the heating or cooling system (the fan will not run if the system switch is in the OFF position and the fan switch is in the AUTO position). When the fan switch is in the ON position, the fan will run continuously, regardless of system switch position (even if the system switch is set to OFF, the fan will run if the fan switch is in the ON position). Thermostat on wallplate. For heat only move the temperature lever to the highest temperature. For cool only move the temperature lever to the lowest temperature.

White Rodgers 1F56N-444 Troubleshooting

Symptom Possible Cause Corrective Action
No Heat/No Cool/No Fan (common problems) 1. Blown fuse or tripped circuit breaker.
2. Furnace power switch to OFF. Turn switch to ON.
3. Furnace blower compartment door or panel loose or not properly installed.

1. Replace fuse or reset breaker.
2. Turn switch to ON.
3. Replace door panel in proper position to engage
safety interlock or door switch.

No Heat

1. Pilot light not lit.
2. Broken or melted anticipator wire.
3. Loose connection to thermostat or system.
4. Thermostat or heating system requires replacement or service.
5. System Switch not set to Heat.

1. Re-light pilot.
2. Excessive current or dead short in system. Have a qualified service person check the system before replacing thermostat.
3. Verify thermostat and system wires are securely attached.
4. Your furnace manufacturer or service person can describe how to test the heating system to verify it is operating correctly. If the heating system is capable of operation and the no heat condition persists, replace the thermostat.
5. Set System Switch to Heat and raise temp above room temp.
Intermittent Heat 1. Furnace Lock-Out Condition Many furnaces have safety devices that shut the system down when a lock-out condition occurs. If the
heat works intermittently contact the furnace manufacturer or local service person for assistance.
No Cool 1. Loose connection to thermostat or system.
2. Thermostat or cooling system requires replacement or service.
3. System Switch not set to Cool.
1. Verify thermostat and system wires are securely attached.
2. Your cooling system manufacturer or service person can describe how to test the cooling system to verify it is operating correctly. If the cooling system is capable of operation and the no cooling condition persists, replace the thermostat.
3. Set System Switch to Cool and lower temp below room temp.
Heat, Cool or Fan Runs Constantly. 1. Possible short in wiring.
2. Possible short in thermostat.
3. Possible short in heat/cool/fan system.
Check each wire connection to the thermostat to verify it is neatly looped under the terminals. No extra wire should stick out from under the terminals.
Furnace Cycles Too Fast or Too Slow Narrow or wide temperature swing See Step 5, Adjusting the Anticipator. The anticipation setting is the only adjustment that effects the heating cycle rate. If an acceptable cycle rate is not achieved using the anticipator contact a local service person for additional suggestions. The location of the thermostat, size of the Heat/Cool System and current draw can influence the cycle rate.
Cooling Cycles Too Fast or Too Slow (narrow or wide temperature swing) 1. Poor thermostat location for sensing room temperature.
2. Cooling system over or undersized.
3. Excessive Current draw influencing thermostat.
The cycle rate for cooling can not be adjusted. The location of the thermostat, size of the Cool system and current draw can influence the cycle rate. Contact a local service person for suggestions.
Thermostat Setting and Thermostat Thermometer Disagree 1. Thermostat thermometer setting requires adjustment.
2. Thermostat setting lever requires calibration.
The thermometer can be adjusted by using a standard slotted screwdriver. Turn the thermometer pointer screw located inside the front cover to change the setting. For calibrating the setting lever contact a local heating and cooling service person.
Adjusting Thermometer 1. Thermostat thermometer disagrees with other room thermometers. The thermometer on the thermostat is accurately calibrated at our factory but you can adjust it by using a standard slotted screwdriver. Turn the thermometer pointer screw located inside the front cover to change the setting.
