and time
Low Battery Indicator:
Replace batteries when
this indicator is shown.
Programmable
Time Period Icons:
This thermostat has
4 programmable time
periods per day.
HOLD is displayed when
thermostat program is
permanently overridden.
The low battery indicator is displayed when
the AA battery power is low. If the user fails to
replace the battery within 21 days, the screen
will only show the low battery indicator but
maintain all functionality. If the user fails to
replace the batteries after an additional 21
days (days 22-42 since rst “low battery”
display) the set points will change to
55˚F(Heating) and 85˚F(Cooling). If the user
adjusts these setpoints away from these it will
hold for 4 hours then return to either 55˚F or
85˚F. After day 42 the batteries must be
replaced immediately to avoid freezing or
overheating because the thermostat will shut
the unit o until the battery is changed.
