Heat Controller
2.3.1 Description of Features and Functions
• Auto-Restart:
The unit will memorize the set conditions before a power failure and resume operation automatically when the
power re-starts.
• Sleep Mode:
This feature helps keep the room conditions at the most desirable levels when you sleep.
• Turbo Mode:
Turbo mode allows the unit to quickly heat or cool and room, at a high speed fan setting.
• Anti-Cold Blow:
In heating mode, this feature prevents cold air from blowing until warm air is ready to be delivered.
• Silver Ion Filter:
The silver filter sterilizes bacteria in the air stream by decomposing cell wall of bacteria.
• Low Ambient Operation:
Allows the unit to operate under low outdoor temperatures.
Gold Hydrophilic Condensers Fin Coating:
•
This coating improves the heating efficiency by accelerating the defrosting process. The anticorrosive gold
coating on the condenser helps withstand salty air and corrosive elements for sea side applications.
• Self Clean:
This function wicks away any moisture, essentially cleaning the inside of indoor unit to prevents bacteria for
forming. This feature is especially useful at the end of the season and/or when the unit will not be used for
an extended period of time.
• Follow me:
A temperature sensor is built in the remote control, which signals the unit to automatically change the
operation mode to supply a comfortable temperature. Using this feature allows the unit to sense the
conditions where you are in the room, rather than up high in the room where it traditionally senses the
conditions via the indoor unit.
• Low Room Temperature Protection:
Allows the unit to maintain a set temperature to protect the area it is installed in from freezing when you will be
away for an extended period of time in the winter.
• Louver Swing and Position Memory:
The louvers can swing to make a breeze like affect in the air flow from the indoor unit. When starting the unit
after shutting down, the louver will restore the user's settings for louver position.
• Refrigerant Leak Detection:
The refrigerant leakage detect function prevents the unit from freezing due to low charge and protects the
compressor from being damaged.
• Self-Diagnosis Function:
The system monitors itself for abnormal operations and turns of the unit automatically to protect it from further
damage, then displays an error code to help troubleshoot the problem for a quick solution.
• Sump Heater:
A PTC heater is installed in the base pan of the outdoor unit to prevent the rain, snow or defrosted water from
accumulating and icing up the unit.
• Compressor Crankcase Heater:
The oil dissolves easily into the refrigerant, especially in low temperature condition, therefore the crankcase
heating belt is used to warm the bottom of the compressor to avoid pumping out too much oil within the
refrigerant, which helps to protect the compressor.
