Auxiliary Regulator
The auxiliary regulator can be activated through the digital input if this is
set to auxiliary (parameter H11=4), or by a key (parameter H31 or H32=4):
in this case, the regulator control must be configured as Aux by setting
parameters H21(22) to 4.
This function is used to energize the relay if it was de-energized, or vice
versa. The relay status is stored in order to maintain correct operation in
the event of a power failure, unless parameter H11 = 4 (aux); in this case,
the relay reflects the status of the digital input. Parameter H13 can also be
used to set the priorities/polarities for activation by key or digital input.
NOTE: the significance of the Digital Input (D.I.) must remain the
same: for example, when activating the relay by D.I. and switching
off with a key, if the D.I. is subsequently deactivated the relay status
will not be changed as it has been switched off by a key.

Soft Start
Note: The SOFT START function can be selected by key, by D.I. or by
a function.
The Soft Start regulator can be used to set the temperature gradient over
which a given setpoint is reached within a predefined time.
With this function, the regulation Setpoint is raised progressively and
automatically from value Ta (ambient temperature when switched on) to
the value actually set on the display; this allows the initial temperature rise
to be slowed down and thus reduce the risk of "overshoot".
Cyclic Regulator
Note: The PERIODIC CYCLE function can be selected by key or by digital input
This function can be associated with both the outputs by relay (by setting
parameters H21, H22 to 2), and can be used to actuate "Duty Cycle" regulation
with the intervals set by parameters Con and CoF.
