Overshoot limit, during PID control process, when
PV(measured value) > SV(set value) + OVS
(overshoot limit), force to close output. The smaller
this value is, the smaller the PID adjustment range
is, the worse the control stability is. Please set the
appropriate value according to the actual situation.
Differential time, the greater the value is, the stronger
the differential actiontion is, otherwise, it is weeker.
When D=0, no differential action. Set D=0 when
controlling fast systems, e.g., pressure, speed; unit: s
Integral time, the smaller the value is, the stronger the
integral action is, otherwise, it is weeker. When I=0,
no integral action, unit: s.
Proportional band, the smaller the value is, the faster
the system responds, otherwise, it is slower. When
P=0, no PID control, unit same as PV

please use the auto-tuning function when the controller is powered on for the first time; if the
temperature control is stable after the auto tuning, there is no need to repeat this step in the
future usage.); control output: SSR; alarm: 1 alarm, when PV>SV+5

Measuring range low limit and high limit.
For temperature sensor input, please keep the factory
setting value. For 4 ~ 20mA / 0 ~ 10V input, please
set the corresponding range for the low limit and the
high limit. For example, 0~10V corresponds to -20~50,
set FL to - 20, set FH to 50. Setting range:
-1999~9999, associated with DP decimal point menu.
4~20mA analog output low limit and high limit. For
example, 4~20mA corresponds to 0~100, set brL to 0,
set brH to 100. Note: it can be set as reverse analog
output, for example, 100~0 corresponds to 4~20mA.
Current control output low limit and high limit, only
valid for 4~20mA current control output. It is used to
limit the output current amplitude. For example, in the
control of frequency converter, if the motor cannot be
stopped, please set the output low limit OLL to 10%;
in heating control, if the user don’ t want full-power
output at the beginning of heating, please set the
output high limit OLH to 80%.
