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 and are being installed and debugged and ready to be put into use are not equipped with any form of simple or intelligent thermostats. The room heating system is equipped with thermostats, especially intelligent thermostats, which is an extremely prominent and important link in the energy-saving heating comprehensive system.
Convenient: Automatically adjust the wall-hung boiler in advance or delayed every day, eliminating manual operation, which is the most necessary for office families;
Comfort: The room temperature is automatically adjusted in the morning, noon and evening every day, so as to avoid the embarrassment of waiting for the room to heat up and freeze after getting up in the morning and returning home from work;
Gas saving: change the backward extensive water temperature control to advanced and accurate room temperature control, plus the time period to set the room temperature on demand, no need to open day and night gas heating;
Rest assured: when the room temperature is too low, the wall-hung boiler is forced to start, and only a very small amount of gas is needed to safely carry out anti-freezing protection in the room.
Thermostats are widely used in various home appliances, such as refrigerators, water dispensers, water heaters, coffee pots, etc. The quality of the thermostat directly affects the safety, performance and life of the whole machine, and is a very critical component. Among the many technical indicators of thermostats, life is one of the most important technical indicators to measure thermostat products. The standard for household appliances stipulates that the life of the thermostat is at least 10,000 times, and the life of some thermostats in some household appliances, such as refrigerator products, which control the motor-compressor, and some thermostats in the liquid-filled radiator, are required to be at least 100,000 times. The corresponding standard GB14536.10-2008/IEC60730-2-9:2004 for household thermostats has detailed provisions on the life test of thermostats.

RK Level Gauge - Four common types of faults and solutions for float level gauges
1. The indicated value is large (or out of range).
According to the investigation of our staff, this kind of problem often appears in the atmospheric pressure workshop. When we find that the counterweight of the float in the float level gauge is at a low point, the liquid level must be very high at this time, and the glass plate is inconsistent with the indication of the instrument.

RRC Thermostat – Instructions for use of smart thermostats
1. Turn on the power of the smart thermostat, and the current temperature is displayed on the display. Because the sensor is not in contact with other devices, but is exposed directly to the air, this is the current temperature: 31 degrees Celsius, which is not too hot.
2. At the bottom right of the display is the "Startup Temperature" setting.

RHK thermostat - the thermostat shows the reasons for the deviation between the temperature and the actual temperature and the solution
The thermostat shows a nonlinear relationship between the temperature and the actual temperature deviation:
(1) The input type of the thermostat is selected incorrectly;
(2) There is no calibration or calibration error in the analog input;
(3) There is interference in the thermostat;
(4) There is interference with thermocouples;
(5) The use of quality is not ...

What are the solutions to the failure of the RRKC thermostat - the sudden thermostat?
1. The cleanliness and finish of the contact surface have a great impact on the working condition of the contact. When the surface of the contact is rough or there is excess material on the contact, it is easy to cause arcing and reduce the life of the contact. Therefore, the parts cleaning process should be improved to eliminate excess materials; Increasing the process of screening excess materials, ...
