IX. REMOTE TEMPERATURE SENSOR

A remote temperature sensor is available to read the tem- perature from a space. If a remote temperature sensor is connected, the thermostat will ignore the reading of its in- ternal sensor. When the thermostat is using a reading from a remote sensor, the degree symbol above the tempera- ture reading will blink.

X. KEYPAD LOCK

To prevent unauthorized use of the thermostat, the front panel buttons can be disabled. To disable or lock the

keypad, press and hold the Mode button. While holding down the Mode button, press the UP and DOWN ARROW buttons simultaneously. The ``Locked'' icon will appear on the display.

The thermostat is unlocked by performing the same pro- cedure. Press and hold the Mode button. While holding down the Mode button, press the UP and DOWN ARROW but- tons simultaneously. The ``Locked'' icon will be removed from the display.
