Nowadays, most of the families are using air conditioners, which can be said to be one of the more common electrical appliances. All air conditioners will display the temperature when they are operating, and most air conditioners will have an LCD display on the surface, which will show the indoor temperature, outdoor temperature, and functions and modes of the air conditioner. Many people do not know what is the air conditioner temperature display, what is the principle of the air conditioner temperature display? We will learn more about the details of the air conditioning temperature display today, we understand the principle and operation of the air conditioning temperature display.
A, LCD
LCD thermostat by the electronic logic circuit of its measured temperature compared with the set temperature, control of the central air conditioning end of the fan, water valves, etc., applied to hotels, office buildings, shopping malls, industrial, medical and especially villas and other civilian buildings, so that the controlled ambient temperature is constant for the set temperature range, this The temperature controller is equipped with a remote control, which can realize long-distance control.
Two, installation method
1.? The controller's driver board (power board) according to the requirements of the diagram to connect the fan coiler, electric valve (solenoid valve or air valve) and power cord.
2.? Connect the LCD motherboard with the power driver board Hu line.
3.? Remove the back cover of the LCD motherboard and embed the power driver board into the pre-embedded box.
4. Fix the back cover with screws.
5.? Snap the panel into the back cover and the installation is complete.
3. Operation
1. For the on/off button, press the button to select the system's on or off state.
2, M: mode key, key to select the control mode of the system, whether it is cooling or heating. Refrigeration is to reduce the ambient temperature, and vice versa is both heating.
3, wind speed key, press the button to select the size of the output wind, wind speed can be divided into three categories: low, medium and high grade, different blades, from more to less on behalf of high, medium and low.
4, set the temperature. You can set the temperature of the high and low, if you need to heat, at this time you set the temperature should be higher than the indoor temperature, the mode is heating, and vice versa lower than the indoor temperature, the mode is cooling.
Four, the principle
Temperature controller is the temperature of the air-conditioning room to control the electrical switching equipment. Temperature controller controlled by the air conditioning room temperature range is generally 18 ℃ -28 ℃. Window air conditioning commonly used temperature controller is the principle of pressure action to promote the contacts on and off. Its structure consists of bellows, temperature-sensitive package (test tube), eccentric wheel, microswitch, etc., composed of a sealed induction system and a system to transfer the signal power.
The above is the introduction of air conditioning temperature display. Everyone now knows what is the air conditioning temperature display? The operation of the air conditioning temperature display is also relatively simple, because all the air conditioning remote control above the display mode, we only need to follow the mode prompts to operate, you can see the air conditioning display temperature. The principle of the air conditioning temperature display is also relatively simple, because the temperature inside the air conditioning room is controlled using an electric switching device, so the temperature will automatically display the temperature in the case of a certain temperature.
