Display does not come on. Set the System switch to Off. Remove batteries. Insert them backward
for at least five seconds to reset the thermostat. Replace batteries
correctly. Display should come on.
Make sure batteries are fresh and installed correctly.
Temperature display does
not go lower than 45°F
(7°C) or higher than 88°F
(31°C) during programming. You have reached the temperature setting limit. The setting range is
45°F to 88°F (7° to 31°C).
Temperature change occurs
at wrong times. Check the program times for the questionable period. Be sure that AM
and PM indications are correct. Make sure the current day and time
are correct. Reprogram, if necessary.
