SYSTEM FUNCTIONS (Continued)
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
The system 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 this 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 Slim Duct B Series
system will automatically return to the last operating mode.
INTELLIGENT DEFROST
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.
FAHRENHEIT / CELSIUS
The remote controller and wired controller can be set to display in either °F or °C.
REMOTE LOCK-OUT
