Referring to the operation and effects of the present invention configured as described above in detail.

First, the present invention is connected to the LCD monitor and the setting unit 19, and when the power supply is applied through the constant voltage unit 12 in the state of connecting the necessary devices for each terminal of Figure 2, the microcomputer 11 is initialized and the LCD By controlling the display (D) to control the display to the initial screen to the alarm sound through the alarm sound output unit 23 for a predetermined time. If the equipment was in operation before the power was supplied, if it was stopped in the fan start screen, the equipment stop screen is displayed.

When you want to operate normally on the equipment stop screen, press the Run / Stop key to display the fan start screen. When the operation starts, turn on the fan first and check whether the fan is normal. If the fan is abnormal, an alarm sounds and the fan error occurs. It is displayed on the screen and if the fan is normal, it is converted to the room temperature and humidity screen.

That is, when the operation / stop key of the LCD monitor and the setting unit 19 is pressed in the stopped state, the microcomputer 11 displays the LCD monitor D based on the data acquired from the temperature sensing unit 22 and the temperature sensing unit 21. The room temperature and humidity are displayed on the room temperature and humidity screen.

On the other hand, when the equipment is stopped during operation, pressing the Run / Stop key appears the fan delay screen and the microcomputer 11 applies a signal to the fan relay (FAN) to operate only the fan.

Here, the fan is displayed by the displayed number displayed on the fan delay screen and then stopped.

Thereafter, all outputs are stopped and key inputs other than the run / stop key are not recognized. In this case, it is preferable to maintain the stop state even after the power failure is restored.

Meanwhile, the controller of the present invention can automatically perform a corresponding operation when a user inputs various settings in advance, which is displayed as a setting temperature screen by pressing a selection key on the room temperature and humidity screen. In this state, you can change the setting value from 10 to 50 ° C by using the up or down key. If there is no key input after the change, it will be converted to the room on / humidity screen after a certain time and the setting value will be saved. The stored value is preferably not erased even when the power is off.

When the selection key is pressed once on the setting temperature screen, the sensing temperature is displayed. When the temperature of the room is detected to be higher than the setting temperature + sensing temperature, the microcomputer 11 applies the contact signal of the terminal unit 10. Turn on the cooling operation relays (CS, C, CF) and start the cooling operation of the room accordingly. If the temperature of the room is detected to be lower than the set temperature-response temperature, the microcomputer 11 contacts the terminals of the terminal 10. The heating operation operation relay (RH) is turned on by applying a signal and the heating operation of the room is started accordingly, and the heating operation is automatically stopped until the internal temperature is equal to the set temperature.

Afterwards, the cooling and heating operation is in progress until the internal temperature is equal to the set temperature. Here, the setting range of the sensitive temperature is 0.5 ~ 5 ° C. If there is no key input after the setting is completed, the set value is stored while switching to the room temperature and humidity screen after a predetermined time.

When the selection key is pressed on the response temperature screen, the setting humidity is displayed. In this state, the setting value can be changed from 35 to 65% using the up or down key. If no key is input after the change, the room is on after a certain time. Change to humidity screen and save setting value.

When the selection key is pressed once on the setting humidity screen, the humidity sensitivity is displayed. When the room humidity is detected to fall below the setting temperature-humidity, the microcomputer 11 applies the contact signal of the terminal unit 10 to humidify. The humidification operation is performed by turning on the operation relay (HU), and if the internal humidity rises above the set humidity + the humidity, the dehumidification operation of the room starts. Automatically stops. Here, the humidification and humidity setting range is 1 to 30% and if there is no key input after the setting, the setting value is stored while switching to the room temperature and humidity screen after a predetermined time.

When the selection key is pressed once in the sensitivity and humidity screen, the screen is switched to a screen for viewing the starting state of each part. The on state is indicated by the corresponding output abbreviation, and the off state is displayed as "-". Here, if there is no key input, the room temperature and humidity screen is switched after a certain time.

If you press the select key once in the starting status screen for each part, the screen changes to the screen where you can set the equipment number.If you want to monitor and control the equipment from a long distance, each equipment needs a unique number and set from 1 to 20 times.

When the select key is pressed on the equipment number screen, an alarm status display screen is displayed. In this state, a number of alarm messages is displayed, and the number of alarms generated is displayed and the corresponding alarm contents are displayed. If there are two or more alarms generated, it is desirable for the operation to change the alarm contents at regular time intervals.

For example, if a compressor alarm occurs, 1 is displayed. This alarm occurs after the delay time has elapsed when the high pressure, low pressure or overload safety device tripped and the MG. After restoring the tripped safety device, press the reset (cancel) key on the LCD monitor and the setting part to display the compressor alarm clear screen.If you press the up key in this state, the compressor alarm is cleared and cooling operation starts again. Here, if you do not want to clear the alarm, press the down key. If you do not clear the alarm, the compressor will not operate.

In the case of the heating heater alarm, the contact of the overheat prevention is opened due to the overheating of the heater during the heating operation.When the alarm occurs, the heater is completely turned off, and when the alarm is returned, the heater is sequentially turned on again.

Humidification heater alarm occurs when the heater is exposed to the water surface and overheated due to lack of water during humidification. The heater is turned off when the alarm occurs and the heater is turned on sequentially when the alarm is returned.

Leakage alarms are caused by leak detection of the water detector and determine the operation of the water supply valve.

If the temperature sensor is over or the cable connected to the sensor is cut off, both cooling and heating outputs will be stopped. If the humidity sensor is over or the cable connected to the sensor is cut off, a.

In addition, the present invention has a built-in test program for function-specific checks for easy commissioning and after-sales service, which is achieved immediately after pressing the LCD monitor switch in the off state (all functions are off). Press and hold down the down key to switch to the fan test screen. Pressing the up key starts the fan and displays On on the monitor. Press the DOWN key to turn off the fan and press the SELECT key to switch to the compressor test screen.
