1. Set temperature: Press the SET button to set or check the temperature set point. Press the SET key digital tube character to flash at the beginning, indicating that the appearance has entered the setting state, press the △ key to add the set value, press the v key to reduce the set value, press and hold the △ button or √ key The data will change rapidly, and press the SET button again to return to the normal working condition and the temperature is set.
2. Return control (XMT201-C): press the SET button for 3 seconds to enter the inner layer parameter setting. The first parameter presented and flashed is CO0, that is, the return difference value, the return control parameters should be carefully adjusted, the appearance of the control heating output value to the set value, when the temperature falls to the set value to reduce the difference value, and then start heating, the output (relay) is not active in the range of the return difference, so that the relay can be reduced to extend the life of the relay.
3. Early setting (XMT201-E): Press the SET button for 3 seconds to enter the inner layer parameter setting. The first parameter presented and flashed is EO0, that is, the early amount of heating abort, the early amount parameter should be carefully adjusted, in order to reduce the temperature overshoot, the heating output will be cut off early. When the temperature drops below the early amount, the heat is started again, and the output (relay) is not operated within the range of the set value and the early amount, so that the number of relay actions can be reduced to extend the life of the relay.
4. Time share setting (XMT201-P): Press the SET button for 3 seconds to enter the inner layer parameter setting. E: is the share band offset, and the E parameter allows the practice control point to be translated. Even if the center of the time share shifts, the E value can be positive or negative depending on the heating system.
5. Intelligent control parameter setting (XMT201-D): press the SET button for 3 seconds to enter the inner layer parameter setting. E: This parameter is the early amount of heating abort when P=O, when P is not equal to 0, the appearance is the working mode of smart PID, and when P is not equal to O, the E parameter is meaningless.
6. Correction of errors: When admitting that the value of the appearance is not the correct measured value, the value of the appearance can be corrected. Press the SET button for 3 seconds to enter the inner menu on the surface, the first parameter presented and flashed is EO0, that is, the early amount, and then press the SET key again to present and flash the parameter that is the error correction parameter, and this parameter can be modified by cooperating △ or V key. The error correction range is -9.9°C to +9.9°C, and after the correction is completed, press the SET button to exit. The correction value of the appearance is 0.0 when leaving the factory, and it is necessary to avoid correcting the correct appearance to incorrect when using.

Common faults and failure analysis of RTC thermostats
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 ...
