Set gradient
The “Set gradient” function sets a gradual variation
of the setpoint, with programmed speed, between two defined
values. If this function is active (
g.sp other than 0), at switch-
on and at auto/man switching the initial setpoint is assumed
equal to the PV, and the local or selected set is reached with
set gradient. Every variation of set, including variations of the
local setpoint, is subject to the gradient.
The value of remote setpoint SP.rS is not saved in eeprom.
The set gradient is inhibited at switch-on when self-
tuning is enabled.

Multiset
The MULTISET function determines the local setpoint
by selecting the value from Setpoint 1 (SP.1) or from Setpoint
2 (SP.2) based on the state of a digital input or by setting from
a serial line.
The variation between Setpoint 1 and Setpoint 2
can take place with gradient: parameter G.SP determines the
speed for reaching Setpoint 1 and parameter G.S2 defines
the speed for reaching Setpoint 2.
The MULTISET function is enabled with parameter
hd.1 and automatically enables the gradient function.
Selection between Setpoint 1 and Setpoint 2 can be seen by
means of LED.
