Error Codes

The thermostat may display an error code to alert you of problems. When an error code is
displayed the temperature is replaced with "E#", where the number represents an error
described below. To clear the error code, press any key on the keypad. Refer to the
Troubleshooting section for corrective action.
The Thermostat Keypad module senses the current
temperature and provides an interface for manual control.
Normally the displayed number (68 in this case) indicates the
current temperature.
To change the set point, press the up or down arrows. The
display will switch to the current set point. Note that a decimal
point is displayed while showing the set point. The display will
automatically revert to the current temperature after a few
seconds if no keys are pressed.
The display will show "LO" to indicate locked if a key is
pressed when the keypad has been locked (using the web
portal).
