RLC Thermostat – Precautions for Thermostat Operation

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 ...

Generally, there are three buttons to provide the need for setting, one is the Set button, press it once to enter the setting state. The other two offer upward and downward temperature adjustments, which can be adjusted to any temperature point. After adjusting to the desired temperature point, press the Set button again to confirm. 1. Turn on the smart thermostat ...

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 ...

1. Bellows or diaphragm air conditioner thermostat Fault Symptom: Poor contact or burning, resulting in the circuit cannot be connected; The frequent action of the contact arc and sticking causes the circuit to be unbreakable; The leakage of the thermostat in the temperature sensing chamber causes the contact to fail to operate and lose control ...

Japan RIKA RKC REX-C400 temperature controller product introduction REX-C400 Digital Thermostat RKC PID Temperature Controller Thermostat (SSR Output) + Type K Thermocouple + *Large 40A SSR Relay 1. Dual display set temperature and process temperature 2. General Digital Programmable Temperature ...

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) It is a display of the common cathode. It uses the principle of the positive electrode as the segmented input, with the ground wire as the common output, and the segmented input is valid as a high-level input. 2) It is a display with a common anode. It uses an anode as an aggregate input, and in contrast to the common cathode, the segment is effective at a low level output ...

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 ...

1. The dry-type transformer thermostat does not appear 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 shining and showing "-OP-" ...

The rkc controller was developed by Japan and is mainly used in plastics and stoves. Of course, it is also widely used in China's industry, there are many people who do not know much about the rkc controller, and some even feel unfamiliar.

(1) Size selection When replacing the thermostat, choose according to the original size; The newly added thermostat should take into account the overall coordination of the cabinet installed, too large to fit, too small to see the display, the same function of the thermostat, the price of large volume will be more expensive, small size may function expansion...

Many household appliances and large-scale equipment products will be installed in the use of thermostats, thermostats will be combined with the change of ambient temperature in the switch when working physical deformation, which will produce some special effects, resulting in conduction or disconnection action, in order to achieve automatic ...

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. Sudden jump thermostat The type of various sudden thermostats is collectively called KSD, such as KSD301, KSD302, etc., the thermostat is a new type of bimetal thermostat, mainly as a variety of electric heating products with overheat protection, generally connected with the thermal fuse in series, sudden temperature ...

Mechanical thermostats are suitable for indoor temperature control in industrial, commercial and residential buildings. The mechanical thermostat uses an inflatable diaphragm box to sense the temperature and compare it with the user's set temperature to automatically control the air conditioning equipment to achieve the purpose of indoor constant temperature. For commercial, industrial and civil construction, available ...

1. The installation of the level gauge must be vertical to ensure that the inner pontoon can move up and down freely in the pipe body. 2. Install a shut-off valve between the container and the liquid level gauge to clean and overhaul the liquid level timing to cut off the material. 3. No magnets are allowed to approach around the main body of the pontoon level gauge, otherwise ...

First, the temperature does not appear 1. Fault with the temperature sensor If the temperature probe of the temperature sensor breaks or the wire is broken, the sensor does not have a digital display when the temperature sensor is connected, but only shows the "----" and sounds an alarm.

1. Bellows or diaphragm air conditioner thermostat 1. Fault phenomenon: poor contact or burning, resulting in the circuit can not be connected; The frequent action of the contact arc and sticking causes the circuit to be unbreakable; The thermostat in the temperature sensing chamber leaks, causing the contact to fail to operate and lose control. ...
