AUX (Auxiliary Regulator)
The Digital Input can be set as “auxiliary”
(parameter H11=5): in this case define the
regulator output 1as aux (auxiliary)
through H21 parameters.
This function permits to activate the relay
if it was not excited or to leave it excited
on the other side. The status will be
stored, to ensure a correct functioning, in
case of black-out, except when you set
parameter H11=5 (aux); in this case the
relay status is the same as the Digital Input
status.
Through parameter H13 you can define
priorities/polarity between atctivation
through key, relay and Digital Input.
NOTE: The meaning of the Digital Input
(D.I.) should remains the same: e.g.
enabling relay from D.I. and disabling it
from key, if you reset the D.I. the relay
doesn’t change its status because it is
disabled from key.
INSTALLATION
The instrument is designed for panel
mounting. Make a hole of 29x71 mm,
insert the instrument and fix it using the
brackets provided. Do not mount the
instrument in humid and/or dirty places; it
is suitable for use in ordinary polluted
places. Ventilate the place in proximity to
the instrument colling slits.
ELECTRICAL
WIRING
Attention! Never work on electrical
connections when the machine is
switched on.
The instrument is equipped with screw ter-
minal boards for connection of electrical
cables with a diameter of 2.5 mm
2
(one
conductor only per terminal for power
connections).
For the capacity of the terminals, see the
label on the instrument.
The relay contacts are voltage free. Do not
exceed the maximum current allowed; in
case of higher loads, use an appropriate
contactor. Make sure the power supply
voltage complies with the one required by
the instrument.
Probe cables, power supply cables and the
TTL serial cables should be distant from
power cables.
In 12V versions the power supply however
could be cabled with the probe cables
and the TTL serial cable.
In 230 V versions the power supply
should be cabled with the loads.
Probes can be extended using a regular
bipolar cable (note that the extension of
the probes affects the EMC electromagnet-
ic compatibility of the instrument: pay
extreme attention to wiring).
NOTE: Pay extreme attention to the
probe connection polarity.

PLEASE NOTE: The technical data
included in this document, related to
measurement (range, accuracy, resolu-
tion, etc.) refer to the instrument
itself, and not to its equipment such as,
for example, sensors.
This means, for example, that sensor(s)
error(s) shall be added to the instru-
ment’s one.
CONDITIONS OF USE
Permitted Use
For safety reasons the instrument must be installed
and used in accordance with the instructions supplied.
Users must not be able to access parts with dangerous
voltage levels under normal operating conditions.
The device must be suitably protected from water and
dust according to the specific application and only be
accessible using special tools (except for the front key-
pad).
The device is ideally suited for household use and/or
similar use in the refrigeration sector and has been
tested with regard to safety in accordance with the
European harmonized reference standards. It is classi-
fied as follows:
• as an automatic electronic control device to be inde-
pendently mounted as regards its construction;
• as a 1 B type operated control device as regards its
automatic operating features;
• as a Class A device as regards the category and
structure of the software.
Unpermitted use
The use of the unit for applications other than those
described is forbidden.
It should be noted that the relay contacts supplied
with the device are functional and therefore exposed
to potential faults.
Any protection devices required to comply with prod-
uct requirements or dictated by common sense due to
obvious safety reasons should be installed externally.
RESPONSIBILITY AND RESIDUAL RISKS
Eliwell & Controlli s.r.l. shall not be liable for any dam-
ages deriving from:
- installation/use other than that prescribed and, in par-
ticular, which does not comply with the safety standards
specified in the regulations and/or those given herein;
- use on equipment that does not guarantee adequate
protection against electric shock, water or dust when
assembled.
- use on equipment that allows dangerous parts to be
accessed without the use of tools;
- tampering with and/or alteration of the product;
