The base module is designed to be mounted behind the front grille
of a packaged terminal air conditioner (PTAC). Refer to the PTAC

Staging Indicaators:
If these or the fan indicators are flashing, it means that the system is in a delay of some
type (compressor delay, cooling fan delay, or staging delay) or a pending change.
Energy Efficient Globe:
Indicates you are making an energy efficient set at
temperature.
Wireless Symbol: Indicates you have a wireless connection.
Low Battery Indicator: Replace batteries when this indicator
appears.
Important
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 first “low battery”display) the setpoints will
change to 55˚F (Heating) and 85˚F (Cooling). If the user adjusts the setpoint away from
either of these, it will hold for 4 hours then return to either 55˚F or 85˚F. After day 63
the batteries must be replaced immediately to avoid freezing or overheating because
the thermostat will shut the unit off until the batteries are changed.
