Robertshaw Smart Sense Series Installation Manual page 50

Turn ON the equipment and power the SMART 2000. When power is first applied,
the thermostat will perform a test display that lights all the segments of the LCD.
This is followed by the software version, then the running display.
Enter the Advanced Installer settings menus. If making changes proceed through
the functions and make any changes that are required. Exit the settings and
perform the following tests.
Test fan operation
With the thermostat OFF (press the MODE button to show OFF in the LCD), press
the FAN button to cycle through the available fan speeds. As the LCD changes to
show the fan speed or fan mode you should hear faint "clicks" as the thermostat
internal relays change. The equipment fan speed should change accordingly.
Test heating and cooling (if both fitted)
Turn the SMART 2000 to Auto changeover mode by pressing the MODE button
until the words HEAT and COOL are shown on the LCD.
Use the Temp p or  buttons to set the desired temperature a few degrees
below the ambient temperature. After a few moments, you will hear a click and
the word HEAT will change to HEATING. Verify that the heating system is ON and
operating correctly. If stage 2 heat is being called for, the thermostat will display
MODE. (with a period after the word MODE) to indicate 2nd stage heat. Stage 3
heat is indicated by MODE with a flashing period.
