THE INSTRUMENT ENABLES MODIFICATION OF OTHER PARAMETERS DIVIDED INTO USER
LEVEL (USr) and INSTALLER LEVEL (InS)
How to modify other parameters
Installer (InS) level access - User level access is similar:
Procedure applies only to more advanced applications. In this case the parameters are arranged in
folders (Compressor / Defrost / Fans etc)
1) Press and hold the SET key for 3 seconds until the display shows PAr / Lite
2) Use the UP & DOWN keys to select the parameter level concerned (Usr or Ins)
3) Press and release the SET key once more. The display will show the first folder
4) Press and release the SET key once more. The upper display will show the first parameter in the
folder, the lower display will indicate the current parameter value
5) Using the UP & DOWN keys, find the parameter that you wish to modify
6) Press and release the SET key once more. The upper display will show the name of the blinking
parameter
7) Use the UP & DOWN keys to adjust the parameter value
8) Press and release SET to save the parameter value
9) Return to step 5) or press ESC several times to return to the normal display
OPERATION IN DEFAULT CONFIGURATION
The instrument is configured for negative cold. For positive cold, disable the evaporator probe Pb2
(set H42=n) and set relay OUT3 (parameter H23=6) to prevent continuous ventilation.
COMPRESSOR
The compressor is active if the cold room temperature detected by Pb1 exceeds the value of SEt +
differential diF. The compressor stops if the cold room temperature detected by Pb1 falls below the
SEt value. The instrument includes compressor on/off protection*
DEFROST
Defrost is by means of electric heaters (parameter dty = 0) and the time counter is always active
with the instrument switched on (dCt=1).
Manual defrost
Manual defrost is activated by pressing and holding the ESC key (B)
If conditions for defrosting are not present, (e.g. the evaporator probe temperature is higher than
the defrost end temperature) or the parameter OdO≠0, the display will blink three times to indicate
that the operation will not be performed.
Default Defrost settings
dit = 6 hours. Interval between 2 defrost cycles
dSt = 6°C. Defrost end temperature. Set by Pb2
The Defrost cycle may terminate due to time-out based on the parameter dEt.
EVAPORATOR FANS
Relay OUT3 is configured as fans relay and is activated in the required cases, according to delays and
parameter settings*
Default fan settings
dt = 0 min. drip time
dFd = Y. Fans off during defrosting
