Q: What does it mean when the * (asterisk) shows above the temp that you have set it for? What does it mean when the * flashes? What does it mean when the * is not showing? THANKS VERY MUCH
Asked by Sam 12 years ago

Verified Reply- SupplyHouse StaffThe Thermostat has a time delay between cooling cycles to allow the head pressure of the compressor to stabilize. If the temperature is adjusted to call for cool within 5 minutes of the last cycle the * icon blinks indicating the thermostat is locked out and the compressor is stabilizing. After 5 minutes, the * icon will stop flashing.

Verified Reply- SupplyHouse StaffCheck the wire connections 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 on how to test the Heat/Cool system for correct operation. If the system operates correctly, replace the thermostat.

Verified Reply- PexSupply StaffAccording to the troubleshooting guide in the manual: If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation you can reset the thermostat by pressing the up and down buttons at the same time while moving the SYSTEM switch from OFF to HEAT. This also resets the factory defaults.

Q: Could you explain why after you replace the battery that unit will show the last temp plus a flame

Verified Reply- PexSupply StaffThe flame appears when the system switch is set to heat. It should have nothing to do with the battery. Refer to the manual ( http://s3.pexsupply.com/manuals/1249544570102/White_Rodgers_1E78-144_Instructions.pdf ) for more information.
