Common questions about manuals, registration, and support for this brand.
To adjust the swing (cycle rate), hold down the Up and Down keys together for 3 seconds. Use the arrow keys to adjust the setting between 0.2°F and 2.0°F. A smaller swing causes more frequent cycles, while a larger swing allows for longer cycles.
The C (common) wire is optional if you use batteries. If the thermostat is hardwired without batteries, the C-wire must be connected to power the display and electronics.
A flashing battery icon indicates that the 2x AAA batteries are low. You should replace them immediately to avoid freezing or overheating issues if the system becomes inoperable.
Select OFF with the system switch, then hold the Up and Down keys for 3 seconds. Use the Up/Down keys to adjust the temperature display offset (from -4°F to +4°F) to match your room thermometer.
