XWA11V-KIT
Walk-In Temp / Door /Alarm / Light Module with Mounting Box and Wiring
1. GENERAL DESCRIPTION
Model XWA11V-KIT, 100x64 mm format, is a microprocessor based light and alarm management controller, suitable for
temperature monitoring in a walk-in cooler or freezer. It is provided with two (2) relay outputs that supply 120 Volts to
control lights and signal an alarm. It is also provided with one (1) NTC probe input for temperature measurement. To
ease installation on existing walk-in coolers the unit has been installed in a VBOX pre-wired with an outboard buzzer,
magnetic door switch (MDS), a 9V battery harness, a pigtail harness for the unit power and the light. There is also a five
pin port that allows the user to program the parameter list with a “Hot Key”.
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
We have responded to many requests to make a change in the way the light key operates. It now
overrides the Digital Input to allow a manual OFF prior to the “Lht” being exhausted.
2. GENERAL WARNINGS
2.1 PLEASE READ BEFORE USING THIS PRODUCT
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
as a safety device.
Check the application limits before proceeding.
2.2 SAFETY PRECAUTIONS **READ ME FIRST!**
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.
Be sure to seal any J-Box with RTV sealant to prevent cold and moisture intrusion.
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 or you may get bad temp readings.(UL SPEC 0873)
The box supplied is not suitable for exterior use. If a water tight box is required contact the distributor.

5.3 HOW TO LOCK THE KEYBOARD
1. Keep the UP and DOWN keys pressed for more than 3 seconds.
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 3seconds the “POF” message will be displayed.
5.4 TO UNLOCK THE KEYBOARD
Keep the UP and DOWN keys pressed together for more than 3seconds. 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 or the door is opened.
With LHt=0 the light remains on until the light button is pushed again or when the door is closed.
The light is switched on every time one of the following conditions happens:
the door is open (i1F = dor)*DOOR SWITCH PRESENT
the presence sensor is activated (i2F = LHt)*OCCUPANCY SENSOR PRESENT
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)*DOOR SWITCH PRESENT
the presence sensor is de-activated (i2F = LHt)*OCCUPANCY SENSOR PRESENT
Light button regulation: i1L = n
FLH (opera mode) The lights will flash (for 2 minutes) every 20 seconds for the FLH time (0-5 min) before the
end of the LHt time as a warning that the lights are about to turn off. (This should only be used for
incandescent or LED lighting only!)
6.2 MANUAL OVERRIDE VIA LIGHT BUTTON OF XWA11V VERSION: 8.8 OR HIGHER ONLY
With the intorduction of V8.8 it is now possible to overrided the light on time with a press of the light button on
the face of the XWA11V. Regardless of mode in which the light had been turned on the Light button will always
overide a door switch activation or occupancy sensor input.
7. INSTALLATION AND MOUNTING
7.1 MOUNTING OF XWA11V
The XWA11V must be mounted on a vertical
panel using the VBOX wall mount box. The
back of the box has two screw mounting
holes and a larger hole for the electrical
connections to pass through.
The Temp range allowed 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.
The Door Switch Magnet should be
mounted no more than ¾” of an inch from
the switch.

8. ELECTRICAL CONNECTIONS
The instrument is provided with ¼” (.250”) fast-on terminal blocks to connect the digital and analog inputs.
Relays and power supply have a Fast-on connection ¼” (.250”). For supply connections use 14 AWG or
larger copper or CU wire only, rated to at least 90°C (194°F). Before connecting cables make sure the power
supply complies with the instrument requirements. Separate the probe cables from the power supply and
output power connections. Do not exceed the maximum current allowed on each relay and in case of heavier
loads use a suitable external relay.
Note: Maximum current allowed for all the loads is 15A.
8.1 PROBE CONNECTIONS
The probe shall be mounted with the bulb upwards to prevent damage 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.
8.2 BATTERY BACK-UP
Battery Back-up will automatically power the XWA display in case of a power failure for up to 36 hours.
Display will flash when battery runs low. (Battery not included)
9. USE OF THE PROGRAMMING “HOT KEY”
The XWA11V units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory to the
“HOT KEY” and vice versa.
9.1 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 and remove the “Hot Key”, then turn it ON again.
NOTE: the “Err” message is displayed for failed programming. In this case push again 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 operation 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.
10. ALARM SIGNALS

10.2 ALARM RECOVERY
Probe alarms: “P1” (probe1 faulty), they automatically stop 10seconds after the probe restarts normal
operation. Check connections before replacing the probe.
Temperature°alarms “HA” and “LA” automatically stop as soon as the thermometer temperature returns to
normal operating values or when the defrost starts.
Door switch alarm “dA” stops as soon as the door is closed.
External alarms “EAL”, “BAL”, “dEF” stop as soon as the external digital input is disabled.
