Mechanical thermostats are suitable for indoor temperature control in industrial, commercial and residential buildings. The mechanical thermostat uses an inflatable diaphragm box to sense the temperature and compare it with the user's set temperature to automatically control the air conditioning equipment to achieve the purpose of indoor constant temperature. It is used in commercial, industrial and civil buildings, and can be used for heating and cooling of central air conditioning. The end coil fan and water valve are controlled. Maintain the ambient temperature of the controlled place within the set temperature range.
The mechanical thermostat compares the measured temperature with the set temperature through the single-chip microcomputer, and controls the fan coil unit, electric valve, electric damper, and electric air outlet at the end of the central air conditioner to keep the controlled ambient temperature constant at the set temperature. In order to improve the comfort of the environment, the thermostat dial hand should be placed in the desired thermostatic position. The functions of the toggle switch are: power switch (ON-OFFOFF); Operating mode switch (HEAT-coolingCOOL), FAN speed switch (low speed L-medium speed M-high speed H). Controllable equipment: It can also be connected to three-speed fan coil unit wind speed, three-wire electric valve, two-wire electric valve, solenoid valve, on-off damper or three-wire damper.
Mechanical thermostats are characterized by:

3. High-tech: Adopt dual temperature sensing technology to meet the high standards of comfort, safety and energy saving. The heating electronic thermostat is mounted directly on the wall and has a temperature range of 10/55°C. When the LED indicator is on, it means that it is heating. It is suitable for automatic temperature regulation control of heating (equipment) system. Equipped with dual temperature sensing technology, it meets the high standards of comfort, safety and energy saving. LCD heating programmable room temperature controller, you can choose the operation mode of manual control or time period programming control (24 time periods per day). It is suitable for the control of electric heating equipment for electric heating and the control of electric drive valves for heating water systems.
4. Beautiful appearance: The thermostat is the core of intelligent heating control. It is composed of high-precision electronic components and has an automatic temperature setting function. Mechanical and electronic thermostats are beautiful in appearance and easy to operate. The digital LCD thermostat can be automatically controlled according to programming; The temperature is preset every day and every week to achieve energy saving and intelligence. The thermostat is a standard switch size with a sleek design that blends easily into the décor. Powerful and affordable thermostats can meet the different needs of customers.
5. Powerful function: multi-information display, including local time, actual room temperature, set temperature, manual and automatic status, etc. Fuzzy logic control function, through the built-in temperature sensor to sense the room temperature, compared with the real temperature. Time temperature and set temperature, through PID (proportional, derivative, integral) calculation and output time proportional control signal, temperature control accuracy up to 0.5°C. Manual/automatic switching, in the automatic working state, the thermostat is temperature controlled according to the program prepared by the user in advance; In the manual working state, it is equivalent to a mechanical thermostat, and the temperature can be set in real time.

The main role and service life of the thermostat - RLC
In most cases, in Europe, the thermostat is a necessary accessory for the wall-hung boiler, and the two are delivered to the user at the same time, and most of the thermostats equipped are intelligent thermostats. In China, nearly 95% of the wall-hung boilers that have been installed in operation and are being installed and debugged and ready to be put into use are not equipped in advance.

Common faults and failure analysis of RTC thermostats
1. The power indication is normal, but the temperature controller has no screen display. Most of this fault is caused by the heating of the voltage regulator element (7805 or 7812) on the thermostat during long-term use, which leads to the breakpoint of the solder joint, and sometimes it is caused by the phenomenon of virtual soldering at the factory, and the main re-soldering can be done.
