Install Batteries

1)
Pull out the battery cover.
2)
Install the batteries as shown. Observe the
polarity.
3)
Reinstall the battery cover. You will hear a clicking
sound.
After the batteries are installed, the thermostat per-
forms a series of tests for approximately 5 seconds.
Afterwards, the screen displays the actual tempera-
ture. It is normal that the displayed temperature be
higher than the ambient temperature if you are holding
the thermostat. The thermostat will display the ambi-
ent temperature once it is installed on the wall. By
default, the setpoint is 70 °F (21 °C).
