RLC thermostat - a classification introduction of floor heating thermostats

Fault 1: The thermostat does not turn on (the screen does not display) Analyze the causes 1. Wrong wiring; 2. The voltage of the input terminal is not enough or the input terminal is damaged by the empty leakage guarantee; 3. Whether the cable between the panel and the power board is broken or plugged incorrectly; 4. Load short circuit or broken ...

(1) Before use, first check whether the level gauge is within the verification cycle, otherwise, it should be calibrated, and replaced in time if it is unqualified. (2) The sensor should be installed horizontally, and the length of the lower entry should meet the technical requirements. (3) The connection between the sensor and the explosion-proof junction box should be tightened and tightened.

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...

In winter, the surface of the power plant's measuring instruments is frozen and condensed, which can lead to poisoning, fire and even explosion. Therefore, the cold and freeze protection of the appearance of the instrument is particularly important. First, the selection method (1) Choose the appearance with insulation device. According to the category of appearance ...

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) Before use, first check whether the level gauge is within the verification cycle, otherwise, it should be calibrated, and replaced in time if it is unqualified. (2) The sensor should be installed horizontally, and the length of the lower entry should meet the technical requirements. (3) The connection between the sensor and the explosion-proof junction box should be tightened and tightened.

1. RH400 size: 48*96, depth 60, about 250g 1. Thermocouples: K, J, R, S, B, E, N, T, W5RE/W6RE, PL‖, U, L 2. Temperature measurement heat resistance input: PT100, JPT100 3. Tributary voltage: DC0 - DC5V, DC1 - DC5V ...

Input: all kinds of thermocouple (TC), RTD standard current and voltage signals (see input type table); Basic error: 0.5% of the input full-scale ±±1 word; Resolution: 1°C, 0.1°C; Sampling period: 3 times/sec Alarm function: ...

1. The level gauge is adjusted normally, and it is found that the float is "absorbed" for a period of time in a certain position after it is put into use. This is mainly caused by the level gauge passing through the steel platform device and being spaced too close to the steel plate. Therefore, it is necessary to pay special attention to the level gauge to connect the pipe wall with the steel platform device.

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 key digital tube character start flashing, indicating that the appearance has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key The data will change rapidly, press the SET key again The appearance will return ...

1. Thermostat output control power: The thermostat output control power is the first issue to consider when choosing a thermostat, which is related to the safety and stability of use, and may cause serious consequences if not selected properly, such as: fire. Thermostat products are marked with output control voltage and current, and the ...

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. Classification of pontoon level gauges The pontoon level gauge is also divided into two types: inner pontoon and outer pontoon, the so-called internal and external division refers to the place where the pontoon is installed, in the container of the liquid to be measured is the inner pontoon, and the outer pontoon is called the outer pontoon outside the liquid container to be measured.

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 ...

1. The buoy level gauge is welded and installed under the guide wire At the bottom of the container, determine the position according to the requirements of the movement direction of the level gauge buoy, and weld or rivet the support under the fixed guide wire. 2. Buoy level gauge ruler installation 1. The connecting part of the ruler should be flat.

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 ...

The instrument can be cleaned only after the power is off; To remove stains from the monitor, use a soft cloth or cotton paper; The display is easy to be scratched, and it is forbidden to use hard objects to operate the panel buttons, otherwise the keys will be damaged or scratched. ...

1. There is no liquid level display or lower liquid level display When the sewage is discharged, only a small amount of condensate flows out, and it is judged that the pontoon is blocked. Treatment: Dismantle the outer pontoon and find that the pontoon is almost filled with dirt and impurities. Clean, calibrate, and return to normal. 2. The liquid level display is ...

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 ...
