Thermostat Quick Reference
Important
The low battery icon is displayed when the AA battery power is low. Whenever the
thermostat detects low battery voltage from the AA batteries, the low battery icon will
begin flashing on the screen for 21 days (if the batteries are not changed). If the batteries
are not changed 22 days after the thermostat detects low battery voltage, the thermostat
screen will only show the flashing battery icon until buttons are pressed. If the batteries
are not changed 43 days after the thermostat detects low battery voltage, the thermostat
screen will only show the flashing battery icon until buttons are pressed and the set points
will offset to 85°F/29°C in cooling and 55°F/13°C in heating. At this stage, set point changes
can be made temporarily but, the set points will change back to defaulted values after a
4-hour period. The thermostat will continue to perform this low battery flashing,
temperature offset condition until the internal voltage threshold is reached. When the
thermostat internal voltage threshold is reached, all relays will be opened and the
thermostat will become inoperable until new batteries are installed.
About The Badge
All of our thermostats use the same universal magnetic badge. Visit the
company website to learn more about our free private label program.
Use the bevel on lower ridge
Magnet in door
Gently slide a screwdriver into the bottom edge
of the badge. Gently turn the screwdriver counter
clockwise. The badge is held on by a magnet in the
well of the battery door. The badge should pry off
easily. DO NOT USE FORCE.
