WK-SM3 temperature control can set the temperature range, open and close the power supply, the standard line length of 2 meters, can be customized
Note: (5000W without a plug, you need to connect your own power line) Product features
1, the installation is simple, without changing the plumbing, floor heating, electric heating pipes and lines;
2, using American microcomputer chip, high integration, digital programming, accurate control, strong anti-interference ability;
3, start temperature, stop temperature, respectively set, respectively display, intuitive reading, simple operation;
4, the new temperature sensor, sensitive response, high accuracy, the sensor can be connected according to user needs, without affecting accuracy
5、HaveAntifreezing functionWhen the boiler water drops to3When the temperature is below centigrade, the circulation pump is forced to start to prevent the pipeline from freezing. HaveOver temperature alarm function. If the water temperature in the system is more than 90 degrees centigrade, the thermostat digital tube flashes and rings, prompting the user to deal with it in time.
SM3 also has high temperature startup and low temperature startup function, and has three groups of digital display. The temperature is displayed in the middle, and the temperature is displayed on the left side. The temperature is displayed on the left side, and the starting temperature is displayed on the right side.
When the starting temperature is higher than the shutdown temperature, the computer is in high temperature starting (suitable for circulating cooling of boiler and pump, etc.). When the measured temperature reaches the starting temperature, the "running" lamp is bright and works with electrical appliance. When the temperature drops to the shutdown temperature, the power supply is cut off. So cycle work. When the starting temperature is lower than the shutdown temperature, it is automatically at low temperature (suitable for heating, heating, etc.). When the temperature is less than the starting temperature, the electric appliance works. Cut off the power supply when the temperature is greater than the shutdown temperature. According to the "heating" arrow, the number increases. Decrease the number of "cooling".
3Forced temperature setting
The manual key can be forced to start (digital tube flashing and ringing), then press once to stop, and press the automatic key to work in the normal setting.
