ADJUSTABLE STATIC PRESSURE SWITCH By using the switch on the control board of the device it is possible to set manually the external static pressure of the unit REFRIGERANT LEAKAGE DETECT If the unit detects refrigerant leakage, a message EC will appear on the indoor unit display and the air-conditioner stops operation. This function additionally protects the compressor against damage. TEMPERATURE COMPENSATION The temperature measured by the sensor placed inside the air conditioner, depending on the unit installation height may differ from the temperature at ground level, even by few degrees. The temperature compensation function allows setting appropriate adjustment, to ensure more accurate temperature control and increase the comfort of air conditioner exploitation. ANTI-COLD AIR FUNCTION By activating the “Anti-cold Air Function” the air conditioner automatically blows hot air to ensure maximum comfort. EMERGENCY OPERATION In case of temperature sensor malfunction, the air conditioner displays an error code without stopping operation. This enables the air conditioner to operate in emergency mode until the arrival of service in cases, where the air conditioning is actually necessary. 2-WAY DRAINING Both left and right sides of indoor unit are possible for drainage hose connection, easy for installation. FOLLOW ME Temperature sensor built in the remote controller will sense its surrounding temperature. So the unit can adjust room temperature more accurately to give you comfort. CENTRAL CONTROLLER The central controller enables you to control up to 64 indoor units. The control can be done individually or in groups. The maximum cable length is 1200m. ERROR ALARM PORT The built-in PCB can output alarm signal, which makes setting up an external alarm light or vibration gauge possible. LOUVER POSITION MEMORY The air conditioner stores the recent setting of the air louvres and restores them every time you turn it on. FRESH AIR Outdoor air can be supplied to the air conditioner with use of additional ventilation duct. This provides the necessary oxygen, making the room conditions even more comfortable. LOW AMBIENT COOLING With a built-in low ambient kit or special designed PCB, outdoor fan speed can be changed automatically according to condensation temperature. The air conditioner can run cooling operation even when the outdoor ambient temperature down to -15℃. WIRED CONTROLLER Compared with an infrared remote controller, a wired controller can be fixed on the wall and avoid mislaying. It’s mainly used for a commercial zone and makes air conditioner control more convenient. 24-HOUR TIMER Set the unit to start and stop operation automatically in a 24 hours period. BUILT-IN DRAIN PUMP The drain pump can lift the condensing water up to 750mm.
