SYSTEM FUNCTIONS
MODE BUTTON
The unit can be set to five different operating modes: HEAT, COOL, DRY, FAN ONLY and AUTO.
NOTE:
AUTO MODE has fixed setpoints of 68° F heating and 77° F cooling, which are
not adjustable. The system will automatically select heating or cooling to maintain room
temperature within this band.
SLEEP MODE
The Sapphire offers three selectable sleep modes for your comfort. The unit will automatically
adjust room temperature during your sleep time. This slight change in temperature will not
affect your comfort level due to the natural effects that sleeping has on the body, but it will
save on energy consumption and will lower electric bills.
X-FAN MODE
When operating in humid areas, Sapphire has a Dry Coil function that will allow the indoor fan
to run for a pre-determined amount of time after the unit is turned off (cooling or dry modes)
to ensure that additional moisture is removed from coil.
FAHRENHEIT °F / CELSIUS °C
The remote controller and
Sapphire indoor wall unit displays can be set to display in either °F or °C.
LOCK MODE
The wireless remote controller has a Lock feature. The Lock averts unauthorized access or
tampering with system settings.
