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.

Analysis of common fault causes of RKC temperature controller
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 causes the solder joint to show a breakpoint, and sometimes it is caused by the phenomenon of virtual soldering at the factory.
2. Temperature controller ...
