1.1 PLEASE READ BEFORE USING THIS MANUAL
• This manual is part of the product and should be kept close to the instrument for easy and quick
reference.
• The instrument shall not be used for purposes diff erent from those des cribed her eunder. It cannot be
used as a safety device.
• Check the application limits before proceeding.
1.2
• Check if the supply voltage is correct before connecting the instrument.
• Do not expos e to water or m oistur e: use the contro ller onl y with in the operati ng li m its avoiding sudd en
Temperature changes with high atmospheric humidity to prevent the formation of condensation.
• Warning: disconnect all electrical connections before performing any maintenance operation.
• Fit the probe where it is not damaged by the end-user. The instrument must not be opened.
• In case of failure or faulty operatio n send the instrument back to the distributor (see address) with a
detailed description of the fault.
• Consider the maximum current that can be applied to each relay (see Technical Data).
• Ensure that the wires for probes, loads and the po wer suppl y are separat ed an d far enough f rom eac h
other, without crossing or intertwining.

2. GENERAL DESCRIPTION
Model XWA11V, 100x64 mm format, is a microprocessor based controller, suitable for temperature
monitoring in a walk-in cooler or freezer. It is provided with two (2) relay outputs to control lights and
signal an alarm. It is also provided with one (1) NTC probe input for temperature measurement. One (1)

To exit: Press SET + UP or wait 15 s without pressing a key.
NOTE: the set value is stored even when the procedure is exited, by waiting the time-out to expire.
5.2 THE HIDDEN MENU (PR2)
The hidden menu includes all the parameters of the instrument.
5.2.1 HOW TO ENTER THE HIDDEN MENU (PR2)
1. Enter the Programming Mode by pressing the Set + down key for 3s (
and
starts blinking).
2. When a parameter is displayed, release and re-press the SET + down for more than 7s.
3. The Pr2 label will be displayed immediately followed from the HY parameter. NOW YOU ARE IN
THE HIDDEN MENU.
4. Select the required parameter.
5. Press the “SET” key to display its value (Now only the
LED is blinking).
6. Use “UP” or “down” to change its value.
7. Press “SET” to store the new value and move to the following parameter.
To exit: Press SET + up or wait 15s without pressing a key.
NOTE: the set value is stored even when the procedure is exited by waiting the time-out to expire.
5.2.2 HOW TO MOVE A PARAMETER FROM THE HIDDEN MENU TO THE FIRST LEVEL AND
VICEVERSA
Each parameter present in the HIDDEN MENU can be removed or put into “THE FIRST LEVEL” (user
level) by pressing “SET + down”.
In HIDDEN MENU when a parameter is present in First Level the decimal point LED is on.
5.3 HOW TO LOCK THE KEYBOARD
1. Keep pressed for more than 3s the UP and DOWN keys.
2. The “POF” message will be displayed and the keyboard will be locked. At this point it will be possible
only to see the Set Point or the MAX o MIN Temp stored
3. If a key is pressed more than 3s the “POF” message will be displayed.
5.4 TO UNLOCK THE KEYBOARD
Keep pressed together for more than 3s the UP and DOWN keys.
6. LIGHT MANAGEMENT
6.1 TIMED REGULATION: I1L = Y
With i1L = y the light remains on at least for the LHt parameter.
The LHt timer is re-initialized every time the light button is pushed.
With LHt=0 the light remains on until the light button is pushed again.
The light is switched on every time one of the following conditions happens:
• the door is open (i1F = dor)
• the presence sensor is activated (i2F = LHt)
• the light button is pushed
The light is switched off when all the following conditions happen:
• the LHt timer is exhausted
• the door is closed (i1F = dor)
• the presence sensor is de-activated (i2F = LHt)

6.2 LIGHT BUTTON REGULATION: I1L = N
The light button has a higher priority than digital inputs therefore:
- if the light was switched on by button the digital input can not modify its status.
- if the light was switched on by digital input, the light button can modify its status.
7. INSTALLATION AND MOUNTING
7.1 MOUNTING OF XWA11V – PR10000
The XWA11V must be mounted on vertical
panel.
The Temp range allowed for correct
operation is 32 – 140°F. Avoid insta llati on is
places subject to strong vibrations, corrosive
gases, excessive dirt or humidity. The same
recommendations apply to probes. Let the air
circulate by the cooling holes.
8. ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal blocks to connect cables with a cross section up to 2,5
2
mm
for the digital and analog inputs. Relays and power supply have a Faston connection (6,3mm). Heatresistant cables have to be used. Before connecting cables make sure the power supply complies with
the instrument requirements. Separate the probe cables from the power supply cables, from the outputs
and the power connections. Do not exceed the maximum current allowed on each relay and in case of
heavier loads use a suitable external relay.
N.B. Maximum current allowed for all the loads is 20A.
8.1 PROBE CONNECTIONS
The probe shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It
is recommended to place the thermostat probe away from air streams to correctly measure the average
room temperature.
9. USE OF THE PROGRAMMING “HOT KEY “
The Wing units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory to the
“Hot Key” and vice-versa.

10.1 SILENCING BUZZER
Once the alarm signal is detected the buzzer can be silenced by pressing the UP key.
10.2 ALARM RECOVERY
Probe alarms : “P1” (probe1 faulty), “P2” ; they automatically stop 10s after the probe restarts normal
operation. Check connections before replacing the probe.
T° alarms “HA” and “LA” automatically stop as soon as the thermostat T° returns to normal values or
when the defrost starts.
Door switch alarm “dA” stops as soon as the door is closed.
External alarms “EAL”, “BAL” stops as soon as the external digital input is disabled.
