SLEEP MODE
Sapphire offers three selectable Sleep Mode functions 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.
ENERGY SAVINGS MODE
This feature will automatically select the optimal compressor and fan speeds to allow for energy savings while
operating in Cooling or Heating modes. The compressor and fan will automatically slow down as the room temperature
reaches the set point.
SELF-DIAGNOSIS
Sapphire has a built-in computer which uses real-time diagnostics which help prolong the unit’s life. The automatic
diagnosis feature continuously scans for errors or malfunctions and fault codes are shown on the unit display to
facilitate troubleshooting and repair.
POWER FAILURE MODE
Power interruptions are no problem for the Sapphire system. User selections and system parameters are stored in
non-volatile memory. These parameters are retained during a power failure. When power is returned, the 3VIR system
will automatically return to the last operating mode.
INTELLIGENT DEFROST
Sapphire’s Intelligent Defrost function increases room comfort and saves energy by eliminating unnecessary defrost
cycles. In heating mode, the unit will monitor the outdoor coil for frost build up. Once frost buildup has been detected,
the system will switch into a defrost mode to remove the frost.
WASHABLE POLYMERIC AIR FILTER
The polymeric mesh filters save energy by preventing the indoor coils from being plugged with dirt and lint. This
economical and sturdy filter may be washed, vacuumed and reused.
FAHRENHEIT / CELSIUS
The remote controller and indoor wall unit front panel can be set to display in either °F or °C.
REMOTE LOCK-OUT
The wireless remote controller has a Lock feature. The Lock averts unauthorized access or tampering with system
settings.
