RKG thermostat – the scope of application of underfloor heating thermostats

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...

1. The cleanliness and finish of the contact surface have a great impact on the working state of the contact. When the appearance of the contact is rough or there is residue 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 the residues; Add the process of residue selection, ...

1) For RTD input, 3 wires with low resistance and no difference should be used. 2) The input signal line should be far away from the power line of the instrument, the power supply line and the load line to avoid noise and annoyance. 3) The power cord of the instrument is generally annoyed by the power supply. 4) Instrument complement ...

1. Electrical parameters: (1) VDE, CQC, UL, TüVAC250V 50-60Hz 10A (resistive load) (2) ULAC125V 50Hz 15A (resistive load) 2. Operating temperature range: -50-270°C (optional), temperature accuracy: ≥ ±2°C 3. Reset and action ...

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET button digital tube characters to start flashing, indicating that the instrument has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, long press the △ key or ▽ key The data will change rapidly, press the SET key again ...

1. Power conversion: convert the voltage (rated 100V) and current (rated 5A or 1A) of the transformer into voltage (several volts) to meet the requirements of weak current components. 2. Isolation: current, secondary side security, and work grounding are used to ensure the safety of people and equipment, while weak current ...

peculiarity 1. Thermocouple, RTD, analog and other signals are freely input, and the range can be set freely. 2. The software adjusts the full degree, the cold end measures the temperature separately, the amplifier is self-stabilizing, and the display accuracy is better than 0.5%FS. 3. Fuzzy theory combined with traditional PID method, fast control ...

　　The power indicator is normal, but the temperature control meter has no on-screen display. This kind of fault is mostly caused by the heating of the voltage regulator element (7805 or 7812) of the temperature controller during long-term use, resulting in a break point in the solder joint, and sometimes a virtual soldering occurs at the factory, resulting in re-soldering. ...

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: ...

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 ...

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. 2. Temperature controller ...

Electronic temperature controller, as the name suggests, is a kind of controller that controls the temperature through electronic circuits, it is mainly used for temperature control of electric heating and plumbing, it is easy to learn in the operation method, and the accuracy of control is also very accurate.

1. The three wiring methods of Pt100 RTD are different in principle: The two-wire system and the three-wire system are measured by the bridge method, and the relationship between the temperature value and the analog output value is given after ***. There is no bridge on the four wires, it is completely just sent with a constant current source, measured by a voltmeter, and the test is given after *** ...

The level gauge is composed of five parts: float, traction cable, guide pulley, hammer pointer, display ruler or magnetic flap. 1. Float: The float is welded with two stainless steel (or carbon steel) fasting cones and one stainless steel (or carbon steel) fasting cylinder.

1. Grounding method: It is connected to the grounding metal parts of the equipment through the metal cover of the thermostat. 2. The thermostat should work in the general indoor environment where the relative humidity of the air is not more than 90%, and there are no corrosive gases, flammable gases and conductive dust. 3. The thermostat adopts contact ...

1. There is no manifestation when the power is on. For this kind of problem, first confirm whether the power supply is there and whether the power supply matches the power supply required by the thermostat, and then check whether the wiring is strong. The problem is still there, then it is the problem of the thermostat itself. 2. There is a manifestation, and the manipulation makes mistakes. The first thing to look at this kind of problem is to look at the control ...

In temperature measurement, thermocouples and RTDs are both contact temperature measurements, and although they both measure the temperature of an object, their principles and characteristics are different. This article first introduces thermocouples, which are widely used in temperature measurement temperature control devices.

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 ...
