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. 

 

Dixell Srl reserves the right to change the composition of its products, even without notice, ensuring the 
same and unchanged functionality. 

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.p.A.” (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.

GENERAL DESCRIPTION 

Model XW10L, format 38x185mm, ,  is a digital thermostat designed for refrigeration applications at 
normal temperature. It has 2 relay outputs to control thermostat and light (configurable). A “Day and 
Night” function with two different set points is fitted for energy saving. It is also provided with up to 
four NTC or PTC probe inputs, the first one for temperature control, the second one for display 
temperature of another point. One of the 2 digital inputs can operate as third temperature probe. The 
fourth probe is used to signal the condenser temperature alarm or to display a temperature. 
The HOT KEY output allows to connect the unit, by means of the external module XJ485-CX,  to a 
network line ModBUS-RTU compatible such as the 

dIXEL 

monitoring units  of X-WEB family. It 

allows to program the controller by means the HOT KEY programming  keyboard.  
The instrument is fully configurable through special parameters that can be easily programmed 
through the keyboard.

CONTROLLING LOADS 

3.1

 

THE REGULATION OUTPUT 

The regulation is performed according to the temperature measured by the probe. 
The instruments are provided with the CH programmable parameter which enables the user to set 
the regulation both for heating or cooling applications: 
· 

 CH = CL: cooling applications  

·  

CH = Ht: heating applications 

 

3.2

 

CH = CL: COOLING APPLICATIONS. 

The Hy value is automatically set above the Set Point. If the temperature increases and reaches set 
point plus differential the compressor is started and then turned off when the temperature reaches 
the set point value again.

In case of fault in the thermostat probe the start and stop of the compressor are timed through 
parameters “COn” and “COF”.

The Hy value is automatically set under the Set Point. If the temperature decreases and reaches set 
point minus differential the regulation output is activated and then turned off when the temperature 
reaches the set point value again.

LIGHT RELAY CONFIGURATION  

The functioning of the auxiliary relay (terminals. 1-3) can be set by the oA3  parameter, according to 
the kind of application. In the following paragraph the possible setting: 
 

3.4.1  Auxiliary thermostat  

I.E.. anti condensing heater) with the possibility of switching it on and off also by keyboard 
 

Parameters involved:  

ACH  Kind of regulation for the auxiliary relay: Ht: heating; cL: cooling; 
SAA  Set point for auxiliary relay  
SHy  Differential for auxiliary relay  
- ArP  Probe for auxiliary relay  
Sdd  Auxiliary output off during defrost 

By means of these 5 parameters the functioning of the auxiliary relay can be set.. The differential is 
given by the SHy parameter. 
The auxiliary relay can be switched on also by the AUX button. In this case it remains on till it’s 
manually switched off. 
 
NOTE: Set oA3 =AUS and ArP= nP (no probe for auxiliary output). 
In this case the relay 1-3 can be activated only by digital input with i1F or i2F = AUS.  
 

3.4.2  On/off  relay – oA3 = onF 

In this case the relay is activated when the controller is turned on and de-activated when the 
controller is turned off. 
 

3.4.3  Neutral zone regulation 

With oA3 = db the relay 1-3 can control a heater element to perform a neutral zone action. 
oA3 cut in = SET-HY 
oA3 cut out = SET  
 

3.4.4  Second compressor  

With oA3 = CP2, the relay 1-3 operates as second compressor:  it is activated in parallel with the 
relay of the first compressor, with a possible delay set in the AC1 parameter. Both the compressors 
are switched off at the same time. 
 

3.4.5 Alarm 

relay 

With oA3 = ALr the relay 1-3 operates as alarm relay. It is activated every time an alarm happens. 
Its status depends on the tbA parameter: if “tbA = y”, the relay is silenced by pressing any key.  
If “tbA n”, the alarm relay remains on until the alarm condition recovers. 
 

3.4.6  Night blind management during energy saving cycles 

With oA3 = HES, the relay 1-3 operates to manage the night blind: the relay is energised when the 
energy saving cycle is activated , by digital input, frontal button  or RTC (optional)
