XMTA-2301 series digital temperature controller has digital display of the temperature measured value and time proportion control function. It has high precision, good reliability, strongcushioning, easy
installation and other advantages. This controller is widely used astemperature measurement and
automatic control in light and heavy industry, such asmetallurgy, chemical, electronic, machinery, textile, plastic, refrigeration, medical treatment,electric oven, and so on.

Meaning of the model code
Connection method
Panel instruction (consult) 1.The measured value display window
2.Setting dial: Through press the "+" and "-" of each dial to set temperature set value.
3. Output indicator: The green light of "OUT" on the panel indicates the situation of output. When the 7.8 terminal of the meter connect, "OUT" green light is brighten.
4. "RST" potentiometer: When between the setting temperature and measurement temperature have static difference deviation, you can use this potentiometer for regulation.The potentiometer
is setting in the middle in the factory.
IV.Method to use 1. This temperature controller should be fixed in the installation hole. Connect the power, sensor and output controlling wires properly according to the connection scheme. It will display the actual measured temperature after switching on.
2. The dial button on the panel of the controller can be set to any temperature you want between 0ºC and 399ºC.
3.Control mode:
When the actual measured temperature don't enter the proportional band and the setting temperature is higher than the actual measured temperature, the terminal "7" and "8" connect , the terminal "7" and "6" disconnect. The load starts heating at the moment and its temperature is going up. When the actual measured temperature don't enter the proportional band and the setting temperature is lower than the actual measured temperature, the terminal "7" and "8" disconnect , the terminal "7" and "6" connect . The load does not heat at the moment and its temperature is going down. After the actual measured temperature entry into the proportional band, the relay start opening and closing according to the controlling rule. The higher temperature , the shorter connecting time of relay between terminal "7" and "8 ", vice versa .The meter control the temperature by the way of changing the average heating power of load.
