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