RKC thermostat - how to set the PID of the thermostat?

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.

1. Set temperature: Press the SET button to set or check the temperature set point. Press the SET button at the beginning of the digital tube character flashing, indicating that the appearance has entered the setting state, press the △ key to add the set value, press the v key to decrease the setting value, press and hold the △ key or √ key The data will change rapidly, press the SET key again ...

1. Lower limit deviation alarm setting: press the SET key to select and display "SLP", the green display screen displays the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter. This parameter indicates the difference between the alarm point and the master setpoint. 2. The upper limit deviation alarm is set ...

Master the common problems of several common intelligent temperature controllers, and solve them by yourself when you encounter problems, and you don't need to spend time and effort to find someone to repair, the common problems are as follows: 1. Heating for a period of time, the temperature does not change. Ambient temperature (e.g., room temperature 25°C) is displayed at all times ...

1. There is no display of dry-type transformer thermostat Cause of failure: (1) The power supply of the thermostat is not connected; (2) The fuse is blown out. Solution: (1) Turn on the power supply; (2) Replace the fuse. 2. The dry-type transformer thermostat shows that one or three phases are flashing and displays "-OP-" ...

When using a temperature controller to control a heater, it is necessary to convert the control calculation results of the temperature controller into electricity and apply it to the heater. Electromagnetic relays, solid state relays or phase controllers are usually used for conversion. Depending on the conversion method, the output of the temperature controller is different ...

The float level gauge is widely used, mainly used in petroleum processing, food processing, chemical industry, water treatment, manufacturing, electric power, papermaking, metallurgy, ships and boilers and other industrial automation processes to measure and control the level. 1. Pay attention to the specific working conditions. As introduced ...

Principle of electronic thermostat: The electronic temperature controller (resistive type) is measured by the method of resistance temperature sensing, and generally uses platinum wire, copper wire, tungsten wire and semiconductor (thermistor, etc.) as the temperature measurement resistor, which has its own advantages and disadvantages. Household Air Conditioner Temperature Controller ...

How liquid expansion thermostats work Liquid expansion thermostat is a physical phenomenon (volume change) that causes the material (generally liquid) in the temperature sensing part of the thermostat to undergo corresponding thermal expansion and cold contraction when the temperature of the controlled object changes, and the diaphragm box connected with the temperature sensing part expands or ...

　　Japan RIKA RKCREX-C400 temperature controller product introduction. REX-C400 Digital Temperature Control Controller, RKCPID Temperature Controller, Temperature Controller, (SSR Output) + Type K Thermocouple + *Large 40ASSR Relay. 1. Dual display set temperature and working ...

Common faults of thermostats 1. There is no display when the power is on. This type of problem first determines whether the power supply is available and whether the power supply matches the power supply required by the thermostat, and then checks whether the wiring is secure. The problem is still there, then it is the problem of the thermostat itself. 2. There is a display, and the control is wrong. This...

* Alarm table {ALM1} (standard built-in) A: Upper limit deviation alarm G: Standby upper and lower limit deviation alarm attached B: Lower limit deviation alarm H: Upper limit input value alarm C: Upper and lower limit deviation alarm J: Lower limit input value alarm D: Alarm in the range K: Attached standby ...

1. Lower limit deviation alarm setting: press the SET key to select and display "SLP", the green display screen displays the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter. This parameter indicates the difference between the alarm point and the master setpoint. 2. The upper limit deviation alarm is set ...

· Wiring warning: - If the instrument fails or an error occurs, which can cause a system failure, install external protection circuits to prevent such accidents; - To prevent damage or failure of the instrument, use appropriate fuses to protect the power cord and input/output cord from strong power shocks. ...

Mechanical thermostat mainly refers to a temperature control method that adjusts refrigeration by rotating the button, with an expanding thermostat, which will automatically expand and contract according to the change of temperature, so as to control the power supply, the most primitive type, and the structure is relatively simple. Advantages of mechanical thermostats: ...

The selection of thermocouples should be based on comprehensive considerations such as the operating temperature range, the required accuracy, the operating atmosphere, the performance of the measured object, the response time and the economic benefits. 1. Selection of measurement accuracy and temperature measurement range 1) The operating temperature is 1300-1800°C, and the accuracy is required to be more accurate than ...

1. Mechanical The sensitive gas diaphragm box or thermal bimetal sheet is used as the temperature sensing element to form the temperature control switch of the mechanical contact. This kind of thermostat is more in the European and American markets, and only a few domestic manufacturers promote such products. Mechanical floor heating thermostats usually have contact currents of no more than 8A, which are suitable for ...

First, the selection of the orientation of the thermostat device 1. Easy to operate locally; 2. It can include the average temperature of the local area; 3. Localities with more human activities; 4. It can avoid cold and heat sources; That is to say, the orientation of the device should be far away from radiators, away from doors and windows...

Take CD901 as an example, L(1) pin to 220 volt live wire, N(2) pin 220 volt neutral wire, 3,4 pins for *** output, 5,6 pins for the second output, 7, 8, 9 pins are alarm output, The rear three pins are connected to thermocouples or PT100 and so on.

1. Under what circumstances should I use a thermostat to expand the module? The gradual development of the heating field is now very well recognized, and more and more users have begun to install electric heating, of course, when installing electric heating for users, they have also encountered some headaches. For example, a large area ...
