CHANGING SET POINT

1. The current temperature in that zone will be displayed in the LCD.

2. Press UP or DOWN button once to display set point for that zone. The LCD will display the current

mode of operation, either heat or cool.

3. Press UP or DOWN button again as needed until new set point is shown.

4. Press SET TEMP button to change temperature between COOL set point and HEAT set point.

5. Pressing HOLD button will hold set point setting indefinitely. Pressing HOLD button again removes

HOLD function.

6. Pressing OUT button will program zone as being unoccupied. Pressing OUT button again changes

zone to occupied. When a zone is set to OUT, desired temperature will be displayed as dashes when
UP and DOWN buttons are pressed.

VIEWING OUTDOOR TEMPERATURE AND INDOOR HUMIDITY

1. Pressing both UP and DOWN buttons simultaneously will display outdoor temperature, if this feature

is included, and indoor humidity. Outdoor temperature will be displayed first for 5 sec, followed by
humidity for 5 sec. Smart Sensor will then return to normal. The humidity value will be humidity level
as measured at user interface.

NOTE:

If All Zone feature has been enabled from user interface, you will not be able to override settings

at Smart Sensor location. The desired temperature will be displayed as dashes when UP and DOWN
buttons are pressed. You must first remove All Zone function by pressing ALL ZONE button on user
interface.

A Smart Sensor does not remove or transfer features from User Interface. It only provides a location within
zone where access is provided to some of User Interface features. Any input that can be provided at Smart
Sensor can also be provided at User Interface.
