If the thermostat is unable to control your system due to an
unexpected battery problem, the thermostat will enter Error
Mode. In this condition, the thermostat flashes “ERR-” on the
LCD display, and shuts off your system.
To correct this problem, replace the batteries with 2 new AA
alkaline batteries, even if you have recently replaced them. Next,
use a paper clip to press the RESET button next to the keypad.
You will need to reprogram your thermostat and confirm normal
operation.
If Error Mode returns, please call Hunter Technical support at
(901) 745-9222 for further information.
Your thermostat will automatically cut-off in Heat mode if the
room temperature rises above 95°F (35°C). It will cut-off in Cool
mode if the room temperature drops below 40°F (4°C).
NOTE: If your system has malfunctioned and no longer
responds to thermostat controls, the Auto Cut-Off will have
no effect.
