4.14.29. GRAD.D - Gradiente di setpoint in decremento

Acronym
GRAD.D PID.1 (or PID.2) SETPOINT GRADIENT IN DECREMENT
The parameter shows and sets the gradient used when the setpoint value is decreased.
If the parameter is "0.0" the gradient is disabled.
Unit of measurement:
Options: 0.0...999.9

4.14.30. UNIT - Unit of measurement of gradient

Acronym
Unit PID.1 (or PID.2) GRADIENT UNIT OF MEASURE
The parameter shows and sets the unit of measurement of gradient GRAD.I and GRAD.D.
The parameter appears only if GRAD.I or GRAD.D are greater than "0.0".
Unit of measurement:
Options: DIG/S
DIG/M = Digit/minute

4.14.31. GRAD.O - Gradient of control output

Acronym
GRAD.O PID.1 (or PID.2) CONTROL OUTPUT GRADIENT
The parameter shows and sets the gradient used by the control output.
The gradient is used to limit rapid changes in the control output.
If the parameter is "0.0" the gradient is disabled.
Unit of measurement:
Options: 0.0...100.0

4.14.32. LBA.TM - Tripping delay

Acronym
LBA.TM PID.1 (or PID.2) WAITING TIME FOR LBA ALARM TRIP
The parameter shows and sets the delay time for tripping of the LBA alarm.
If the parameter is "0.0" the LBA alarm is disabled.
When the LBA alarm is active, it is automatically cancelled if the PV rises (in heating) or lowers (in cooling), or by setting
the parameter AL.ACK = On on the user configuration menu or by switching to Manual mode.
This parameter will not appear in the presence of ON-OFF control (of heating, cooling and heating, and
heating/cooling).
Unit of measurement:
Options: 0.0...500.0

4.14.33. LBA.PW - Power delivered when LBA alarm trips

Acronym
LBA.PW PID.1 (or PID.2) POWER LIMITS BY LBA ALARM CONDITION
The parameter shows and sets the power value delivered when the LBA alarm trips.
This parameter will not appear in the presence of ON-OFF control (of heating, cooling and heating, and heating/cooling).
In the presence of PID control with ON-OFF heating or cooling, power . may be set for the PID part only
Unit of measurement:
Options: -100.0...100.0
