The Room Freeze Protection (RFP) function is used in unoccupied spaces during the winter to protect equipment or appliances from being damaged by freezing temperatures. This function is not applicable if the unit is connected to a multi split outdoor unit.

Operation:

When RFP is selected by pressing the RFP button, the unit operates in Heat mode with high fan speed for proper room temperature monitoring. If the room temperature drops below the set temperature (50°F or 46°F), the compressor starts. When the temperature rises above the set temperature, the compressor stops. This cycle repeats continuously.

This operation overwrites the current operation mode and can be cancelled by pressing the MODE button.

Disclaimer:

This function may not work if the unit is not energized, is in protection mode, or in the event of a power failure. During RFP mode, POWERFUL, QUIET, and FAN SPEED selections are disabled. Consult with your HVAC installer for more details.

To cancel a timer: Press TIMER ON or TIMER OFF to select the respective setting (1 or 2), then press CANCEL.

To restore a cancelled timer: If the timer was cancelled manually or due to a power failure, press TIMER ON or TIMER OFF to select the setting (1 or 2), then press SET.

The nearest timer setting is displayed and will activate in sequence. The timer operation follows the remote control’s clock setting and will repeat daily once set.

The FIREPLACE function helps distribute heat equally from an external heat source (like a fireplace) throughout the room. It does this by continuously blowing air from the indoor unit even when the compressor is off. This function is only available during Heat mode operation and is not applicable if connected to a multi split outdoor unit.

• To activate: Press the FIREPLACE button during Heat mode operation.

• Fan Speed: The fan speed adjusts automatically based on the difference between the set temperature and the room temperature. A larger difference results in a higher fan speed.

• To change operation: You can change the operation mode by pressing the MODE or FIREPLACE button.

• To cancel: Press the FIREPLACE button again to cancel. The operation is memorized after the unit is turned off and on again.

• ECO mode and FAN SPEED/QUIET mode can be selected at the same time.

• POWERFUL mode, FAN SPEED, and QUIET mode cannot be selected at the same time.
