Room Freeze Protection Function (RFP)
Room Freeze Protection function (RFP) is used in spaces that are unoccupied during the winter, for the purpose of
protecting any equipment or appliances which may be destroyed as a result of freezing temperature.
To select Room Freeze Protection
When selected, the unit will circulate the air in High mode for monitoring the temperature. When the sensor detects the
temperature drops below 46°F / 8°C the compressor/heat pump operation begins, when the temperature reaches 50°F /
10°C, the compressor stops and repeat this cycle.
ROOM FREEZE PROTECTION FUNCTION (RFP) OPERATION
When the RFP is selected, the unit will operate the fan at high speed for proper room temperature monitoring. When the
sensor detects that the room temperature has dropped below 46°F / 8°C, the compressor/heat pump operation begins.
When the room temperature reaches 50°F / 10°C, the unit shuts off, then will repeat continuously if the temperature
drops below 46°F / 8°C again.
<Disclaimer>
This function may not be performed if the unit is not energized, or under a certain condition that unit is unable to operate
such as in protection mode. Please consult with the HVAC installers or professional for details.
The Room Freeze Protection function (RFP) cannot be used unless the unit is energized and set into the RFP mode.
In the advent of a power failure this mode will not function. During the RFP mode, POWERFUL OPERATION, QUIET
OPERATION and FAN SPEED selection are all disabled. Please consult with you HVAC installer or professional for
more details.
