Downloading Logged Data

The logged data is stored in the internal memory of the logger organized in log blocks. The period of time stored in each block, and the maximum capacity of the internal memory, depend on the log interval (L1 parameter). To download the data of the last closed log or ongoing log, press the SET key. To download all the logged data, press the P key.

The logger has a slot for SD cards that allows transferring the stored data for display on a computer or to be saved as a backup. These data are saved in spread sheet format (.csv), organized in the following way:

Each log block is saved in a file, whose name is the day, hour, and minutes of the first log it contains.
Two files are generated whose name is the year, month, and day of the download, in two different folders ALL and ALARMS. The first contains the file with all the data logged by the device until then and the second contains the file with the events saved until then.

IMPORTANT: Do not remove the SD card until the indicator turns off. The download may take several minutes depending on the data saved.

Warnings

The unit should be installed in a place protected from vibrations, water and corrosive gases, where the ambient temperature does not exceed the value indicated in the technical data.
For the unit to operate correctly, use only the probes supplied by AKO.
For the reading to be correct, the probe should be used in a place without heat influences apart from the temperature you want to measure or control.
The probe and its cable should NEVER be installed in a conduit together with power, control or feeder cables.
In the event of lengthening the NTC probe, always used shield cable and earth the mesh. In these cases, the maximum deviation will be 0.25 ºC from -40 ºC to +20 ºC (Maximum 1000 m with a minimum section of 0.5 mm2 ). We recommend using the AKO-15586 cable.
Always disconnect the power supply to do the wiring.
The power circuit should be equipped with a switch marked as disconnecting device of the equipment of at least 2 A, 230 V, situated near the appliance.
The power supply cable should be H05VV-F or H05V-K type. The gauge will depend on local regulations, but should in no case be less than 1 mm2 . The electrical installation should be carried out under the pipe.
Using the logger not observing the manufacturer’s instructions may alter the appliance safety requirements. Only probes supplied by AKO should be used for the appliance to operate correctly.

Structure of the logged data

The logged data are stored in the internal memory of the logger organised in log blocks. The period of time stored in each block, and the maximum capacity of the internal memory, depend on the log interval (L1 parameter), as shown in table.
The logger has a slot for SD cards, that allows transferring the stored data for display on a computer or to be saved as a backup. These data are saved in spread sheet format (.csv), organised in the following way:

Log interval	Period stored by block	Internal memory capacity
1 min	8 hours	> 50 days
5 min	24 hours	> 5 months
15 min	7 days	> 3 years
30 min	14 days	> 6 years
60 min	28 days	> 12 years

Downloads the data of the last closed log or ongoing log ( or SET keys)

Each log block is saved in a file, whose name is the day, hour and minutes of the first log it contains.

IMPORTANT

Do not remove the SD card until the indicator turns off.
The download may take several minutes depending on the data saved.

Downloads ALL the logged data ( key)

Two files are generated whose name is the year, month and day of the download, in two different folders ALL and ALARMS. The first contains the file with all the data logged by the device until then and the second contains the file with the events saved until then (see section 5.2):

Data of the start of the first log contained in the block.
File recording date.

Alarm log

This function saves an event whenever an alarm is activated or deactivated. To download the events log data, press the P key, all the data logged up to date are downloaded onto the SD
card, including the events log, contained in the “ALARMS” folder.

Initial start-up

The date and time will be requested during the first start-up.

Programming menu (parameters)

To access the parameter programming menu, press the + keys at the same time. Refer to the list of available parameters in section 5 of this manual. After 20 seconds without touching any key, the unit returns to the previous level. If it is in level 3 the changes will not be saved.

Parameter and message table

The Def. column indicates the factory default parameters. Unless otherwise indicated, the temperature values are expressed in ºC (equivalent temperature in ºF).
