D0 and D1 values below. If you change the D0 and D1 values of the channel, you can change the
channel characteristics. D0 and D1 are allowed to be adjusted ± 1000 on the basis of factory settings. If
the current mode uses Celsius, the adjustment range is ± 100.0 ° C. If the current mode uses Fahrenheit,
the adjustment range is ± 100.0 ° F. The allowed adjustment range of D0 is- 1000
～
1000, D1 allowable
adjustment range
The range is (maximum temperature in current mode-1000) ~ (maximum temperature in current mode +
1000). If the set value exceeds this range, MTC will not receive it and keep the original valid settings.
If the measured value of MTC is higher than 5 ° C in actual use, the current channel mode uses mode 3,
and the error can be eliminated by setting the two points P0 (0, -50) and P1 (12000, 11950), see figure 5-
3.

5.2 control function
5.2.1 manual control
When the control mode setting unit BFM#1000 ~ BFM#1003 is set to 0, the corresponding channel of
MTC will perform manual control. The output will be output according to the manual output set value
(BFM#1016 ~ BFM#1019) according to the control cycle (BFM#917 ~ BFM#920).
5.2.2 ON/OFF control
When the control mode setting unit BFM#1000 ~ BFM#1003 is set to 1, the corresponding channel of
MTC will perform ON/OFF control. In the ON/OFF control, the control output is set as OFF when the
measured value is greater than the temperature set value, and ON when the measured value is less than
the temperature set value.
Setting the dead zone of ON/OFF control, namely the adjustment sensitivity (BFM#1024 ~ BFM#1027),
can prevent the output from repeatedly changing ON/OFF.
