Description

Background

Temperature thermostat is an electrical switching device that controls the temperature of air-conditioned rooms. The central air conditioner temperature controller is specially designed for controlling fan coil units, and is 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 control the room temperature

Working principle

The working principle of the central air conditioner temperature thermostat is an electronic switch device which can control the temperature of the room where air conditioning is installed.

Its structure consists of bellows, temperature sensor (test tube), eccentric wheel and microswitch, which form a sealed induction system and a system for transmitting signal power.Temperature controllers generally control the temperature between 18℃ and 28℃. Its working principle is to regulate and control by the principle of pressure, and push the contact point in the controller to work by pressure.

Type of temperature controller:

FCU room thermostat is widely used in Fan Coil Unit system Which to control fans and motorized zone valves of heating/cooling central air-conditioning，There are availble options includes Wifi, 3 speed,LCD  etc.

Precautions for temperature thermostat  of central air conditioner

• The wiring must be operated according to the correct wiring diagram. Do not mix magazines such as water, mud and dust into the temperature controller, otherwise the parts will be damaged.
• The output control power of temperature controller is related to the safe and stable use, which may cause serious consequences if it is not properly selected. Temperature controller products are marked with output control voltage and current, and the 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 temperature controller. Otherwise, the temperature controller will be damaged and a fire will be caused seriously!
• It is best to have free flowing air around the place where the temperature controller is installed and the temperature should be stable. Also avoid installing the thermostat in a place with direct sunlight. When the interior is being renovated, it is best not to install the thermostat first.
• Some brands of thermostats support multi-voltage input central air-conditioning thermostats, so it is necessary to ensure that the input voltage is consistent with the allowable input voltage. Another point should be raised, that is, some thermostats do not support the on-off of DC power, or the DC voltage that can be turned on and off is small, so you should consult the merchants clearly when purchasing thermostats, so as not to cause unnecessary troubles.
