Press the SET button to set or view the temperature set point, press the SET button digital tube character to start flashing, indicating that the instrument 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 △ button or ▽ key The data will change rapidly, press the SET button again and the instrument returns to the normal working state The temperature setting is completed.

C00 is the return difference,

The differential control parameters should be carefully adjusted, the instrument controls the heating output value to the set value, when the temperature falls to the set value and subtracts the difference value, it starts to heat again, and then the output (relay) within the range of the differential is not active, so that the number of relay actions can be reduced to prolong the life of the relay.

E00 is the advance amount of heating stop, the advance parameter should be carefully adjusted, in order to reduce the temperature overshoot, the instrument will cut off the heating in advance when the heating output, when the temperature falls below the advance amount and start heating, the output (relay) is not active within the range of the set value and the advance amount, so that the relay action can be reduced to prolong the relay life

E: is the proportional offset, the E parameter can make the actual control point translate, even if the center of the time scale shifts, depending on the heating system different E values can be positive or negative,

P: is the proportional band, that is, the proportional control value, in order to facilitate understanding and also to make the proportional with a larger representation space, the proportional zone of this instrument is a unilateral proportional band, that is, the actual proportional zone is 2 times the P value. With the actual control point as the center, the output heating ratio is evenly distributed from 0% to 100% in the P-value range.

T: For the heating output cycle cycle, that is, the relay working cycle cycle, the T value is small and the control effect is good, but the T value is too small The relay will reduce the life due to frequent work.

E: This parameter is the advance amount of heating stop when P = 0, when P is not equal to 0, the instrument is the intelligent PID working mode, when P is not equal to 0, the E parameter is meaningless, P: is the proportional band, that is, the proportional control value, the instrument is centered on the set value, the P value is distributed on both sides of the set point, and the instrument works in PID mode within the P value range, T: is the heating output cycle cycle, that is, the relay work cycle cycle, the T value is small and the control effect is good, but the T value is too small The relay will reduce the life due to frequent work.
