The Installer Options section allows the system and programming parameters
to be set up at installation. The Installer Options mode is menu driven. As the

normal operating mode after the last Installer Option mode has been set or by
pressing the RETURN and PROG buttons at the same time.
NOTE: The thermostat will return to normal operating mode automatically after
30 seconds if no key is pressed.
NOTE:
