Low Battery Warning
Your thermostat has a low battery warning system. When the
batteries are detected to be weak, the low battery warning is
indicated by “Low Batt” alternating on the LCD display with
the day. You then need to replace the batteries with 2 new AAA alkaline batteries. You
have 30 seconds to change
the batteries before the set-
tings are lost.

49 Error Mode
E r r o r
If the thermostat is unable to control your system due to an
unexpected problem, the thermostat will enter Error Mode. In
this condition, the thermostat flashes “Error” and a code num-
ber on the LCD display, and shuts off your system.
To correct this problem, replace the batteries with 2 new
AAA 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 888-830-1326 for further information.
