XWA11V
Walk-In Temp / Door /Alarm / Light Module

1. GENERAL DESCRIPTION
Model XWA11V, 100x64 mm format, is a microprocessor-based controller, suitable for temperature
monitoring and alarming in a walk-in cooler or freezer. It is provided with two (2) Dry Contacts to control lights
and an external alarms. It is provided with one (1) NTC probe input for temperature measurement. The unit
nd
has 2 Digital Inputs, one for a Door Switch and the 2 as an optional Panic Switch. See the catalog for
optional accessories. One 5Pin Input allows the user to program the parameter list with a “Hot Key” (see
section 9)
Note: The default settings are listed in the back of this manual. They are set for Coolers (Medium
Temp). For Freezers (Low Temp) you MUST Change the ALL and ALU settings. See Section 4.0
2. GENERAL WARNINGS
2.1

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 different from those described hereunder. It cannot be used

SAFETY PRECAUTIONS

Check if the supply voltage is correct before connecting the instrument.
Do not expose the back of the instrument to water or moisture: use the controller only within the operating limits
avoiding sudden 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 operation 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 power supply are separated and far enough from each other, without
crossing or intertwining.

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. The “PON” message is displayed
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)
• 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, in a J-Box or wall mount using the
VS-BOX2
The Ambient Temp range for correct
operation is 32 – 140°F. Avoid installation in
places subject to strong vibrations, corrosive
gases, excessive dirt or humidity. The same
recommendations apply to probes.

8. ELECTRICAL CONNECTIONS
2
The instrument is provided with screw terminal blocks to connect cables with a cross section up to 2,5 mm
for the digital and analog inputs. Relays and power supply have a Fast-on 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 15A.
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. The probe can be extended up to 300 ft. Check calibration when running long lengths over
100ft.
9. USE OF THE PROGRAMMING “HOT KEY “
9.1 HOW TO PROGRAM A HOT KEY FROM THE INSTRUMENT (UPLOAD)
1. Program one controller with the front keypad.
2. When the controller is ON, insert the “Hot key” and push UP key; the "uPL" message appears followed a
by flashing “End”
3. Push “SET” key and the End will stop flashing.
4. Turn OFF the instrument remove the “Hot Key”, then turn it ON again.
NOTE: the “Err” message is displayed for failed programming. In this case push again o key if you want to restart
the upload again or remove the “Hot key” to abort the operation.
9.2 HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY (DOWNLOAD)
1. Turn OFF the instrument.
2. Insert a programmed “Hot Key” into the 5 PIN receptacle and then turn the Controller ON.
3. Automatically the parameter list of the “Hot Key” is downloaded into the Controller memory, the “doL”
message is blinking followed a by flashing “End”.
4. After 10 seconds the instrument will restart working with the new parameters.
5. Remove the “Hot Key”..
NOTE the message “Err” is displayed for failed programming. In this case turn the unit off and then on if you want
to restart the download again or remove the “Hot key” to abort the operation.

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.
