StE
Period to switch from normal mode to energy saving mode (valid if ErA=bAS):
(0.0 to
24h00min, res. 10 min) if door stay closed for
StE
time, the energy saving mode will be
activated. NOTE: this will require a door switch to work.
EtS
Period to switch from energy saving mode to normal mode (valid if ErA=bAS):
(0.0 to
24h00min, res. 10 min) maximum time for energy saving mode. NOTE: this will require a door
switch to work.
dS
Door open time to switch from EtS to StE (valid if ErA=bAS):
(0 to 999 sec) the energy
saving mode will be immediately deactivated as soon as the door stay open more than the
dS
time. NOTE: this will require a door switch to work.

DIGITAL INPUTS
The free voltage digital input is programmable in different configurations by the
i1F
and
i2F
.
DOOR SWITCH (ixF=dor)
It signals the door status and the corresponding relay output status through the
odC
parameter:
no
= normal (any change);
FAn
= Fan OFF;
CPr
= Compressor OFF;
F-C
= Compressor and fan OFF.
Since the door is opened, after the delay time set through parameter
did
, the door alarm is enabled,
the display shows the message
“
dA
”
and
the regulation restarts if rrd = Y.
The alarm stops as soon
as the external digital input is disabled again. With the door open, the high and low temperature alarms
are disabled.
START DEFROST (ixF=dEF)
It starts a defrost if there are the right conditions. After finishing any defrost, the normal regulation will
restart only if the digital input is disabled, otherwise the instrument will wait until the
MdF
safety time is
expired.
ENERGY SAVING (ixF=ES)
The energy saving mode will be enabled / disabled with the digital input.
MOTION SENSOR (ixF=EMt)
It counts the motion sensor detections.
AUXILIARY OUTPUT (ixF=AUS)
The AUX output (if present and configured) will be enabled / disabled with the digital input.
EXTERNAL WARNING ALARM (ixF=EAL)
It is used to detect an external alarm. It does not lock the regulation.
EXTERNAL LOCK ALARM (ixF=bAL)
It is used to detect any critical external alarm. It locks immediately the regulation.
EXTERNAL PRESSURE ALARM (ixF=PAL)
It is used to detect any pressure external alarm. This signal locks the regulation after
nPS
events in
dxd
interval od time.
EVAPORATOR FAN MODE (ixF=FAn)
It is used to control the evaporator fan.
REMOTE HOLYDAY MODE (ixF=HdF)
It is used to force the holyday mode.
REMOTE ONOFF (ixF=onF)
It is used to switch ON and OFF the device remotely.
LIGHT OUTPUT (ixF=LiG)
It is used to control the light output.
CHANGE CONFIGURATION (ixF=CC)
It is used to change the controller configuration.
MOTION SENSOR DETECTOR (ixF=EMt)
To use the X-MOD motion sensor. Please note that motion sensor can be connected only to the
HOTKEY port, so it needs digital input 2 properly configurated.

INSTALLATION AND MOUNTING
Instrument
XR77CHC
shall be mounted on vertical panel, in a
29x71 mm hole, and fixed using the special bracket supplied.
The temperature range allowed for correct operation is 0 to 60°C.
Avoid places subject to strong vibrations, corrosive gases,
excessive dirt or humidity. The same recommendations apply to
probes. Let air circulate by the cooling holes.
16
OPTIONAL FEATURES
The
MDP/CX
rear cover can be used to increase the protection
from water and dust.
The
HOT-KEY
is used for a quick and easy upload (from device
to
HOT-KEY
) or download (from
HOT-KEY
to device) the
parameter map.
The
XJ485LE
serial interface converts the TTL output into an
RS485 signal that can be used to connect the unit to the
controlling and supervising system. Please note that other
version of this converter does not work with XR-CHC devices.

ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal block to connect cables with a cross section up to
2.5mm
2
. Before connecting cables make sure the power supply complies with the instrument’s
requirements. Separate the probe cables from the power supply cables, from the outputs and the
