4 - Operations
Proportional
band
This parameter specifies the pro-
portional band coefficient that mul-
tiplies the error (SP - PV)
Integral time
It is the integral time value, that
specifies the time required by the
integral term to generate an output
equivalent to the proportional term.
When
Off the integral term is not
included in the control algorithm.
#t.i.
#p.b.
Derivative
time
It is the time required by the propor-
tional term P to repeat the output pro-
vided by the derivative term D. When
Off the derivative term is not includ-
ed in the control algorithm.
Control output
cycle time
Cycle time
cool
It’s the cycle time of the time pro-
portioning control output. The PID
control output is provided through
the pulse width modulation of the
digital waveform.
Overshoot
control
This parameter specifies the span
of action of the overshoot control.
Setting lower values (0.99 —> 0.01)
the overshoot generated by a
Setpoint change is reduced. The
overshoot control doesn’t affect
the effectiveness of the PID
algorithm.
#O.C.
#t.c. C
#t.c.
#t.d.
Setting 1, the overshoot control
is disabled.
Heat/Cool
dead band
This parameter specifies the width
of the deadband between the Cool
and the Heat channel.
Control output
high limit
Cool output
high limit
It specifies the maximum value the
control output can be set
Control output
hysteresis
Cool output
hysteresis
Control output hysteresis span, set
in % of the full scale.
