The caution items are classified into “ Warning” and “ Caution”. The “ Warning” Warnings items are especially important since they can lead to death or serious injury if they are not followed closely. Insufficient safety measures may cause a fall accident. In case of R410A refrigerant models, be sure to use pipes, flare nuts and tools for the exclusive use of the R410A refrigerant. Never attempt to modify the equipment. The use of inappropriate parts or tools may cause an electrical shock, excessive heat generation or fire. If the plug has dust or loose connection, it may cause an electrical shock or fire. Be sure to install the product correctly by using the provided standard For unitary type installation frame. Faulty insulation may cause an electrical shock. Be sure to check the drainage of the indoor unit after the repair. Faulty drainage may cause the water to enter the room and wet the furniture and floor. Frequency Principle Main Control The compressor is frequency-controlled during normal operation. The target frequency is set by the following 2 parameters coming from the operating indoor unit: Parameters The load condition of the operating indoor unit The difference between the room temperature and the set temperature. Quick heating and quick cooling The compressor rotational speed is increased when starting the heating (or cooling). This enables a quick set temperature. The flap provides an optimum control area in cooling, heating and dry mode. Dual Flaps Heating Mode During heating mode, the large flap enables direct warm air straight downwards. This is done through rotation speed control, or phase Hall IC control. Since the microcomputer controls both the temperature and air flow volume, the temperature adjustment and fan adjustment buttons are inoperable in this mode. In Case of The microcomputer automatically sets the temperature and fan settings. Thermostat OFF Condition The temperature difference is in the zone A.http://www.progettorlando.unina.it/public/4-page-quality-manual.xml
Thermostat ON Condition The temperature difference is above the zone C after being in the zone A. The system resumes from defrost control in any zones except A. The Night Set circuit maintains the airflow setting made by users. The Night Set The Night Set circuit continues heating or cooling the room at the set temperature for the first Circuit one hour, then automatically raises the temperature setting slightly in the case of cooling, or lowers it slightly in the case of heating, for economical operations. This mode is particularly convenient for energy-saving-oriented users. It is also a major bonus for those whose breaker capacities do not allow the use of multiple electrical devices and air conditioners. But as thermostat is prone to be off by the fact that the set temperature has been shifted, the thermostat-off action is prohibited in 40 minutes so as to prevent this phenomena. The system sets a target discharge temperature according to the outdoor and indoor heat Exchanger exchanger temperature, and controls the electronic expansion valve opening so that the Thermistor. Exchanger The system sets a target discharge pipe temperature according to the outdoor and indoor Thermistor heat exchanger temperature, and controls the electronic expansion valve opening so that the target discharge temperature can be obtained. Exchanger The system sets a target discharge temperature according to the outdoor and indoor heat exchanger temperature, and controls the electronic expansion valve opening so that the Thermistor target discharge temperature can be obtained. Exchanger The system sets a target discharge pipe temperature according to the outdoor and indoor Thermistor heat exchanger temperature, and controls the electronic expansion valve opening so that the target discharge temperature can be obtained. The function is explained as follows. 1. For limiting lower limit Frequency management is carried out only when the frequency rises. 5.http://www.jdcampus.co.uk/uploads/4-port-manual-kvm-switch.xml
If the discharge pipe temperature rises above a certain level, the operating frequency upper limit is set to keep this temperature from going up further. Detail Zones (typical value) Management within the Zone. Detail Conditions for Start Controlling Judge the controlling start with the indoor heat exchanger temperature after 2 sec from. The defrosting time or outdoor heat exchanger temperature must be more than its fixed value when finishing. Detail Conditions for Starting Defrost The starting conditions must be made with the outdoor air temperature and heat exchanger temperature. Set the upper limit of the indoor heat exchanger temperature by its operating frequency of Hz. Separate into three zones, reset zone, keep zone and drooping zone and the frequency control must be carried out in such zones. If any is disconnected, open the electronic expansion valve according to the outdoor air temperature and the operating frequency and operate for a specified time, and then stop. Relating to Thermistor Malfunction 1. Outdoor heat exchanger thermistor 2. Discharge pipe thermistor 3. Fin thermistor 4. Gas pipe thermistor 5. If local wiring is unclear in the case of buried piping, for example, just press the wiring error check switch that is behind the right-hand panel of the outdoor unit. Setting to only heat (H): Short-circuit pins 1 and 3 of the connector. Setting to only cool (C): short-circuit pins 3 and 5 of the connector. The following specifications apply to the connector housing and pins. Every user would like to know the correct method of operation of the room air conditioner, to check if it is capable of cooling (or heating) well, and to know a clever method of using it. Incorrect work will cause electric shocks, fire etc. Although leaks should not occur, if for some reason any refrigerant happens to leak into the room, make sure it does not come in contact with any flame as of gas heaters, kerosene heaters or gas range.http://www.drupalitalia.org/node/67563
