DESCRIPTION
HACCP (folder with “HCP” label)
SHH: Set High HACCP. Maximum HACCP alarm threshold: when the thermostat control
probe temperature value displayed exceeds the band limits preset by the “SHH” value for
longer than parameter “drA” an HACCP alarm is indicated and the LED/(alarm relay) lights
up for parameter H50 (see). The return differential from the alarm condition is 0.1 °C.
SLH: Set Low HACCP. Minimum HACCP alarm threshold: when the thermostat control probe
temperature value displayed exceeds the band preset by the “SLH” value for longer than
parameter “drA” an HACCP alarm is indicated when the LED/(alarm relay) lights up for para-
meter H50 (see). The return differential from the alarm condition is 0.1°C.
drA: delay record Alarm. Minimum holding time in critical area until event is logged: when
this time has elapsed an HACCP alarm is logged and signalled.
drH: delay register HACCP. HACCP alarm reset time from last reset: the period of time that
must elapse from start-up of the device until logged alarms are automatically reset. If the
parameter is set to 0 the automatic reset is disabled and only the manual reset is activated.
H50: enable HACCP functions and alarm relay: 0= HACCP alarms disabled 1= HACCP alarms
enabled and alarm relay disabled. 2= HACCP alarms enabled and alarm relay enabled.
H51: HACCP alarm exclusion time. This parameter determines the alarm exclusion time after
shut-down (or start-up depending on the sign in parameter H11) of the D.I. digital input
and/or after pressing the button (selectable with parameters H31...H33). If an HACCP alarm
is already present at the start of a defrost cycle and/or opening of the D.I.(or a button is
pressed) the maximum (or minimum) temperature reached and the holding time continue
to be logged until the value read by the thermostat control probe returns within the band
defined by parameters “SHH” and “SLH”.

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 volt-
age levels under normal operating condi-
tions.
The device must be suitably protected
from water and dust according to the spe-
cific application and only be accessible
using special tools (except for the front
keypad).
The device can be fitted to equipment 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 stan-
dards.
It is classified as follows:
• as an automatic electronic control
device to be independently 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 cate-
gory 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 product requirements or dictated by
common sense due to obvious safety rea-
sons should be installed externally.
RESPONSIBILITY AND RESIDUAL RISKS
Eliwell & Controlli S.r.L. shall not be liable
for any damages deriving from:
• installation/use other than that pre-
scribed and, in particular, which does not
comply with the safety standards specified
in the regulations and/or those given here-
in;
• use on boards which do not guarantee
adequate protection against electric shock,
water or dust when assembled;
• use on boards which allow dangerous
parts to be accessed without the use of
tools;
• tampering with and/or alteration of the
product;
• installation/use on boards that do not
comply with the standards and regulations
in force.

ed such as probes, for example.
This means, for example, that an error
introduced by the probe is added to
any error that is typical of the instru-
ment.
