Installation of the probes
To achieve maximum performance from the advanced controller, the correct installation of the probes is key, as they are responsible for
calculating the evaporator's thermal transfer coefficient, evaluating the start and end of the defrosts and diagnosing problems in the evaporator.
Material included
• 4 mm hermetic evaporator probe, 1.5 m of cable.
• Ambient probe
• 1 mounting clip for 10 – 13 mm coil
• 1 mounting clip for 14 – 18 mm coil
• 1 mounting clip for 19 – 21 mm coil
• 1 mounting clip for 22 – 25 mm coil
Location of the ambient probe
The probe should be located in a place that does not directly receive the flow of cold air from the evaporator.
Preferably in its air aspiration area.
Location of the evaporator probe
The probe must be located as near as possible to the inlet of refrigerant from the evaporator (close to the expansion valve) in the finned
area. In certain evaporators, for example cubic ones, this inlet may be located on the front part of the battery, just behind the fan.
If defrost is done by electric heat, the probe must be located far away from them and, if possible, in the area of the evaporator where
defrosting is slower, in other words, in the last area to defrost.
If the two conditions are not possible, the best possible compromise must be looked for.
Select the appropriate clip depending on
the size of its evaporator pipe.
Initial configuration (wizard)
The first time the unit receives the power supply, it will enter into ASSISTANT mode. The display will show
the message
flashing with 0.
Step 1:
Select the most suitable InI option based on the type of installation to be carried out and press SET. The
available options will be shown in the following table:

Attach the probe to the pipe using the clip,
making sure that its end is in direct contact
with the tube.
