Thermostat Honeywell White Rodgers
|Symptoms||Possible cause||Corrective Action|
|No Heat/No Cool/No Fan
1. Blown fuse or tripped circuit breaker.
|Replace fuse or reset breaker.
Turn switch to ON
Replace door panel in proper position to engage safety interlock or door switch.
|No Heat||1. Pilot light not lit.
2. System Switch not set to Heat.
3. Loose connection to thermostat or system.
4. Furnace Lockout Condition. Heat may also be intermittent.
5. Heating System requires service or thermostat requires replacement.
Set system switch to Heat and raise set point above room temperature.
Verify thermostat and system wires are securely attached.
Many furnaces have safety devices that shut the system down when a lockout condition occurs. If the heat works intermittently contact the furnace manufacturer or local service person for assistance.
Diagnostic: Set system switch to heat and raise the set point above room temperature. Within a few seconds the thermostat should make a soft click sound. This sound usually indicated the thermostat is operating properly. If the thermostat does not click, try the reset operation listed above. If the thermostat does not click, it may indicate the need for a new thermostat. If the thermostat clicks, contact the furnace manufacturer or a service person to verify the heating system is operating correctly.
|No Cool||1. System Switch not set to Cool.
2. Loss connection to thermostat or system
3. Cooling system requires service or thermostat requires replacement
|Set system switch to cool and lower set point below
Verify thermostat and system wires are securely attached.
Same procedure as diagnostic for no heat condition except set the thermostat to cool and lower the set point below the room temperature. There may be up to a five-minute delay before thermostat clicks in cooling if compressor lockout is selected.
|Heat, cool or fan runs constantly.||1. Fan switch set to fan on
2. Possible short in wiring.
3. Possible short in thermostat.
4. Possible short in Heat/cool/Fan system.
|Check each wire connection to verify they are not shorted or touching together. NO bare wire should stick out from under terminal screws. Try resetting the thermostat. If the condition persists the manufacturer of your system or service person can instruct you how to test the Heat/Cool system for correct operation. If the system operates correctly, replace the thermostat.|
|Furnace Cycles Too Fast or Too Slow.(narrow or wide temperature swing)||1.The location of the thermostat and/or the size of the heating system may be influencing the cycle rate||Most of our thermostats allow you to adjust the cycle rate. Consult your operation manual for specifics.|
|Cooling Cycles Too Fast or Too Slow.(narrow or wide temperature swing)||1.The location of the thermostat and/or the size of the cooling system may be influencing the cycle rate||The cycle rate for cooling is fixed and can not be adjusted on most models. If this is a need, use the White Rodgers 1F90 series which allows the cooling cycle rate to be adjusted.|
|Thermostat setting and thermometer disagree||1.Thermostat thermometer setting requires adjustment.||The thermometer can be adjusted +/- 4 degrees on most digital thermostats we stock. No other adjustment is possible.|
|Clock loses or gains time||1. Loss of power to thermostat and low batteries.||The thermostat will maintain its program in memory even with no power o r no batteries but the clock time will be incorrect when power is restored. See no Heat/no Cool/No fan (common problems) above for items to check in the system.|
|Thermostat does not follow program||1. AM or PM set incorrectly in program
2. AM or PM set incorrectly on the clock.
3. Voltage spike or static discharge.
|Check current clock and program settings including the AM or PM designations for each time period. If a voltage spike or static discharge occurs reset your thermostat following the instructions in your manual.|
|Blank Display and or Keypad Not Responding||1. Loss of power and dead batteries.
2. Voltage spike or static discharge.
|Replace batteries and check heat/cool system for proper operation. If a voltage spike or static discharge occurs reset your thermostat following the instructions in your manual.|

3. Why is it important to have accuracy within 1°?
Most people sense a temperature change around 1.8°. Honeywell and White Rodgers thermostats are more accurate than some electronic thermostats which can vary up to 9°. Do not be fooled by off-brand or cheap thermostats at home centers.
4. What is the difference between a programmable and a non-programmable thermostat?
A non-programmable thermostat has the ability to regulate room temperature to one desired setpoint. The setting on the thermostat must be manually changed if a new temperature setpoint is desired. Programmable thermostats allow flexibility to homeowners because they can be programmed to match their lifestyle. A programmable thermostat will keep you and your home comfortable while you are there to enjoy it, and will change the setpoint at programmed times to an energy savings level when you are not home. By simply planning your schedule, you can enjoy the benefits of personalized comfort and enhanced energy savings.
5. Why select a programmable thermostat?
Installing a programmable thermostat can save you up to 33% on heating and cooling costs. The thermostat will pay for itself, usually in the first season of use, and will continue to save you money year after year. Programmable thermostats are also good for the environment since they help save energy. Our thermostats even come preprogrammed with standard settings that can be easily modified.
6. What is Smart Response?
Honeywell's patented Smart Response Technology takes the guesswork out of programming your thermostat. This exclusive feature maximizes energy savings and comfort by providing you with the right temperature at the right time. Want it 72° at 6am? Simply program the unit that way. There is no need to set your thermostat for 5:15am and hope your home is comfortable by 6am.
7. What is Energy Management Recovery?
White Rodgers EMR allows you to program a time and temperature and will calculate when the unit should come on to reach that temperature. It allows for more efficiency and precise control of your program. If you want it to be 68 degrees at 8:00 pm, the thermostat will take care of the rest.
8. What is 5-2, 5-1-1, and 7-day programming?
We design our thermostats to be easy and convenient for you. We offer 5-2 programming which enables you to set two temperature schedules - one for weekdays, the other for weekends. 5-1-1 programming provides you with the added flexibility of setting different programs for Saturday and Sunday. And our 7-day programmable units enable you to have varied settings for each day of the week.
9. How easy is it to install a thermostat?
Installing a thermostat is a simple do-it-yourself home improvement that can be done in under 30 minutes. Follow these steps and remember to check the owner's manual before installation. 1. Turn off power and remove the old thermostat. 2. Label wires, attach thermostat mounting plate to wall and connect wires to terminals. 3. Snap thermostat onto mounting plate.
