If a voltage spike or static discharge blanks out the display 
or causes erratic thermostat operation, you may need to 
reset the thermostat. To reset, the System Switch must be 
in 

Cool or Heat. Simultaneously press 

 and 

 buttons 

for approximately 10 seconds until the display goes blank. If 
the thermostat has power, has been reset and still does not 
function correctly contact your heating/cooling service person 
or place of purchase.

1. Blown fuse or tripped circuit breaker.
2. Furnace power switch to OFF.
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.

1. System Switch not set to Heat.

2. Loose connection to thermostat or 
    system
3. Heating System requires service or 
    thermostat requires replacement.

1. Set System Switch to Heat and raise setpoint above 

room temperature.

2. Verify thermostat and system wires are securely 

attached.

3. Diagnostic: Set System Switch to Heat and raise 

the setpoint above room temperature. Within a five 
minutes the thermostat should make a soft click 
sound. This sound usually indicates the thermostat 
is operating properly. If the thermostat does not click, 
try the reset operation listed above. If the thermostat 
does not click after being reset contact your heating 
and cooling service person or place of purchase for 
a replacement. If the thermostat clicks, contact the 
furnace manufacturer or a service person to verify the 
heating system is operating correctly.

1. System Switch not set to Cool.

2. Loose connection to thermostat or 
    system.
3. Cooling System requires service or 
    thermostat requires replacement

1. Set System Switch to Cool and lower setpoint below 

room temperature.

2. Verify thermostat and system wires are securely 

attached.

3. Same procedures as diagnostic for No Heat condition 

except set the thermostat to Cool and lower the 
setpoint below the room temperature. There may be up 
to a five minute delay before the thermostat clicks in 
Cooling if the compressor lock-out option is selected in 
the configuration menu (Item 6). 

1. Possible short in wiring.
2. Possible short in thermostat.
3. Possible short in Heat/Cool/Fan 
    system.
4. Fan Switch set to Fan On.

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 as described above. If the condition persists, 
the manufacturer of your system or service person 
can instruct you on how to test the Heat/Cool/ system 
for correct operation. If the system operates correctly, 
replace the thermostat.

1. The location of the thermostat and/or 
    the size of the Heating or Cooling 
    System may be influencing the cycle 
    rate.

Item 4 (CR Heat) or 5 (CR Cool) in the Configuration 
Menu is the adjustment that controls the cycle rate. If an 
acceptable cycle rate is not achieved using the FA (Fast) 
or SL (Slow) adjustment contact a local service person 
for additional suggestions.

1. Thermostat thermometer setting 
    requires adjustment.

The thermometer can be adjusted +/- degrees as listed in 
item 8 of the Configuration Menu (see page 5). No other 
adjustment is possible.

If a voltage spike or static discharge occurs use the Reset 
Operation listed above.
