Precautions for the use of central air conditioning thermostat
What is a thermostat? What is the thermostat used for? How does the thermostat work? This series of questions is that I want to talk to you today, let’s increase our knowledge!
1. What is a thermostat
The temperature controller is an electric switch device that controls the temperature of an air-conditioned room. Central air-conditioning thermostats are specially developed and designed for controlling fan coil units, and are widely used in heating, cooling, and ventilation control. The speed of the fan can be controlled manually or automatically by adjusting the wind speed button to achieve the purpose of controlling the room temperature. There are two types of central air-conditioning thermostats, one is mechanical and the other is liquid crystal. Nowadays, LCD is generally used. One of its advantages is that it is equipped with a remote control, which can realize remote control operation. The thermostat is used to turn on and off the air conditioner. It is mainly used to control the fan and solenoid valve. Its functions are mainly to adjust the air temperature, humidity, airflow speed, cleanliness, timing, etc.
2. The working principle of central air conditioning thermostat
The working principle of the central air-conditioning thermostat is actually not as complicated as we thought. Speaking of thermostats, it is actually an electronic switch device that can regulate the temperature of air-conditioned rooms. Generally, the temperature control range of a thermostat is between 18°C and 28°C. Its working principle is actually to regulate and control through the principle of pressure action, and push the contact points in the controller to work through pressure.
Three, central air conditioning thermostat precautions
1. The wiring must be operated in accordance with the correct wiring diagram. Do not allow magazines such as water, mud, dust, etc. to be mixed into the thermostat, otherwise the parts will be damaged.
2. The output control power of the thermostat is related to the safety and stability of use. If it is selected incorrectly, it may cause serious consequences. The thermostat products are marked with output control voltage and current, and output control power can be obtained by multiplying the output control voltage and current. The operating power of the controlled equipment must be less than the output control power of the thermostat. Otherwise, the thermostat will be damaged, and serious fire will be caused!
3. It is better to have free flowing air around the place where the thermostat is installed and the temperature should be stable. Also avoid installing the thermostat in a place exposed to direct sunlight. When the interior is being decorated, it is best not to install the thermostat first.
4. Some brands of thermostats support multi-voltage input central air-conditioning thermostats. Ensure that the input voltage is consistent with the allowable input voltage. There is another point that needs to be raised, that is, some thermostats do not support the on and off of DC power, or the DC voltage that can be switched on and off is relatively small. When buying a thermostat, please consult with the merchant to avoid unnecessary Trouble.
