1. GENERAL WARNING

1.1 PLEASE READ BEFORE USING THIS MANUAL

• This manual is part of the product and should be kept near 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.

1.2

SAFETY PRECAUTIONS

• Check the supply voltage is correct before connecting the instrument.

• Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden temperature changes with high

atmospheric humidity to prevent formation of condensation

• Warning: disconnect all electrical connections before any kind of maintenance.

• Fit the probe where it is not accessible by the End User. The instrument must not be opened.

• In case of failure or faulty operation send the instrument back to the distributor or to “Dixell s.r.l.” (see address) with a detailed description of

the fault.

• Consider the maximum current which 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.

• In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with inductive loads could be useful.

2. GENERAL DESCRIPTION

The XLH360 is microprocessor controller, suitable for applications on medium or low temperature refrigerating units. It has 6 output relays to
control compressor, heating elements, defrost/extractor fan, fan, de-humidifier/light and humidifier. It has 2 NTC inputs one for thermostat the other
one for defrost. It’s also present a 4÷20mA input for humidity. There is one digital input (free contact) configurable by parameter. An output allows
the user to program the parameter list with the “Hot Key”.

3. TEMPERATURE REGULATION

The temperature regulation is performed through neutral zone using compressor and heater output relays.

ON

OFF

• Heating output: CUT IN is “SET TEMP-dbt”, CUT OUT is when the temperature reaches the set point.

Set point

• Compressor output CUT IN is “ SET TEMP +dbt”, CUT OUT is when the temperature reaches the set point.

3.1 DEFROST

During defrost the temperature control is disabled.

If the second relay is configured as defrost: oA2=dEF then two defrost modes are available through the “tdF” parameter: defrost with electrical
heater (tdF=rE) or hot gas (tdF= in). The defrost interval is control by means of parameter “EdF”: (EdF=in) the defrost is made every “IdF” time,
(EdF=Sd) the interval “IdF” is calculate through Smart Defrost algorithm (only when the compressor is ON). At the end of defrost dripping time is
started, set by “Fdt” parameter. To disable the defrost set the MdF parameter to zero

If oA2 is different from dEF, defrost is made only by stopping compressor (tdF=rE).
To disable defrosts set MdF=0.

Humidity regulation during defrost depends on the Hud parameter.
With Hud=no humidity regulation is disabled.
Con Hud=yES humidity regulation is performed also during defrost.

4. HUMIDITY REGULATION

The humidity regulation is performed through neutral zone, by humidifying dehumidifying actions.
Humidity control can be disabled setting the SET %RH to “nu” value. In this case only the temperature control is perform.

4.1 HUMIDIFYING ACTION

The humidifying action is done enabling the humidifier relay when the humidity is lower than the “SET %RH-dbH” value.
The relay is switch off when humidity reaches the set values.

4.2 DEHUMIDIFYING ACTION WITHOUT DEHUMIDIFIER RELAY, OA1 DIFFERENT FROM DEH

In this case the dehumidifying action is performed by setting the following parameters in this way:

tHu = c-H kind of dehumidifying by means of heating and compressor relays
oA1 different from dEH:

The heating and compressor outputs are activated together when humidity is higher than SET %RH+dbH value. Outputs are disabled when
humidity comes back to the SET %RH value.

4.2.1 Relation between cooling, heating and dehumidifying

1. If is simultaneously present a request of cooling (temp>SET TEMP+dbt) and dehumidifying (RH > SET %RH+dbH): the cooling action has
the priority over the dehumidifying action: only the compressor relay is energised till the SET TEMP is reached at this point also the heating
relay is enabled.

2. If is simultaneously present a request of heating (temp< SET TEMP-dbt) and dehumidifying (RH > SET %RH+dbH): the dehumidifying
action has the priority over the heating action: both the compressor and the heating relays are energised till the humidity set is reached at
this point only the heating relay is enabled.

4.3 DEHUMIDIFYING ACTION WITH DEHUMIDIFIER RELAY, OA1 = DEH

The configurable relay is used, setting the parameter oA1 =dEH.
NOTE: the LIGHT button is not more available; Two kinds of de-humidifying are available:

4.3.1 Dehumidifying action with ONLY de-humidifier relay

By setting the parameter tHu = db the de-humidifying action is performed by enabling the de-humidifier relay when the humidity is higher than SET
%RH + dbH.
The relay is switch off when humidity comes back to the SET %RH value.

4.3.2 Dehumidifying action with de-humidifier and compressor relays

By setting the parameter tHu = cHu the de-humidifying action is performed by enabling the de-humidifier and compressor relays together. when
the humidity is higher than SET %RH + dbH. The relays are switched off when humidity comes back to the SET %RH value.

If is simultaneously present a request of cooling (temp>SET TEMP+dbt) and dehumidifying (RH > SET %RH+dbH): the cooling action has the
priority over the dehumidifying action: only the compressor relay is energised till the SET TEMP is reached at this point also the de-humidifier is
enabled.

5. FA NS

The fan control mode is selected by means of the “FnC” parameter:
FnC=C-n fans will switch ON and OFF with the compressor and not run during defrost:;
FnC= O-n fans will run continuously, but not during defrost
FnC=C-y fans will switch ON and OFF with the compressor and run during defrost;
FnC=O-y fans will run continuously also during defrost

6. EXTRACTOR FAN

6.1 EXTRACTOR FAN CYCLES

The second relay is configured as extractor fan, oA2= ESt, then it is possible to make extraction cycles, both manually and
automatically.

Extraction cycle can be activated both manually by pushing the UP key for 3s, and automatically by the internal time rFi. Cycle duration is set by
the rFd parameter. The cycle can be stopped also by key.

If rFI = 0 only manual cycle can be activated.
If rFd = 0 the cycle is stopped only by pushing the key.

7. MATURING CYCLE WITH DRIPPING, RUNNING AND STOPPING PHASE.

Operating Instructions

cod. 1592017410

The diagrams displays a typical maturing cycle with the starting dripping phase.

DRIPPING PHASE lasts for the “dri” time, without humidity control, temperature set is SETG
RUNNING PHASE lasts for the “on” time, both temperature and humidity are controlled.
STOPPING PHASE lasts for the “off” time, without any control of temperature and humidity.

The end of the stopping phase is signalled by the internal buzzer and by the “End” message on the display.

After the STOPPING PHASE the behaviour of the controller depends on the parameter trc, according to the following settings:
