Thermostat Keypad
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).
HEAT
The indicator is illuminated when the thermostat is in heat mode. The key is used to select
heat mode or turn the furnace off.
COOL
The indicator is illuminated when the thermostat is in cool mode. The key is used to select
cool mode or turn the air conditioner off.
HOLD
The indicator is illuminated when the thermostat is in hold mode. The key is used to select or
cancel hold mode. When in hold mode, the current set point will be used regardless of what is
scheduled. Note that the web and mobile portals can still override this setting.
FAN
The indicator is illuminated when the fan is running manually. The key is used to manually
turn the fan ON, or set it in automatic.
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.
