Hour meter display: Number of hours worked by the compressor
NOTE:
If the number of hours of the compressor exceeds 999, the number will be shown in two steps:
Thousands first and then hundreds, tens and units.
6.2 - Manual defrost (instant)
To perform a manual defrost regardless of programming, keep the key pressed for 4 seconds until
the indication is shown. Release the key and will appear.
If the instrument is in the defrost cycle and an interruption is required, proceed as per the instructions
above until the indication is shown. Release the key and will appear.
6.3 - Minimum and maximum temperature register
By pressing , short touch, the sign will appear and the maximum and minimum temperatures
of the sensor S1(ambient temperature) will appear. Soon will appear showing the minimum and
maximum temperatures of the sensor S2 (evaporator). Next will appear the minimum and maximum
voltages, preceded by the sign .
Note:
To reset settings, hold the key through all the minimum and maximum temperature
visualization until appear.

6.7 - Manual datalogger activation
Press and simultaneously for 10 seconds to activate or deactivate the operation of the internal
voltage recorder (data-logger). The message will be showned followed by the message
when the data-logger is activated and when it is deactivated.
Note: The status of the datalogger will only change alternate between and if the function
F46 is set to 2 (manual datalogger operation).
6.8 - Hour-meter reset
When the number of hours with the compressor on reaches the value set in F63, the display will show a
warning, indicating that maintenance should be done. To reset this counter (It can be done only
after the warning occurs), press for 10 seconds.
6.9 - Turn off the control functions
Pressing for 5 seconds, the controller will go to a state where only temperatures and voltages are
read, where no control are performed and where all outputs kept off. Communication with SITRAD
software and the Datalogger will still work. To make the device fully operational again, press again
for 5 seconds.

to enter the function. Use the or keys
to choose between or and confirm
with the key. After selecting the unit the message will appear, and the instrument will return
to the function . Whenever the unit is altered, the parameters should be reconfigured, since they
assume ”standard” values.

IMPORTANT
As chapters of IEC 60 364 norms:
1:
Install protectors against over voltage on power supply
2:
Sensor cables and computer signals can be together, however not at the same place where power supply
And load drive pass for.
3:
Install suppresor of transient (RC filter) in parallel to loads, as for to increase the useful life of the relays.
