Each installation and start-up requires control and eventually a correction of the actual value correction
after 2 to 3 hours runtime.
Why?
Temperatur is measured before the evaporator coil (return air), this value is sometimes different to
the average temperature inside the cabinet, depending on the conditions of the location.
Factory setting was done for 25 °C room temperature. According to different ambient conditions there are many
influences to the installed refrigerated equipment. With this parameter H12 it is possible to correct actual value
deviations caused by sensor tolerances, very long sensor cables or surrounding conditions. of the location.
Sample:
Sunshine, heating sources or raised room temperature causes higher temperatures inside the
cabinet than shown on the digital display.
Sample:
Conditioned rooms (about 22 °C) causes lower temperatures inside the cabinet than shown on the
digital display.
Which temperature is inside the cabinet?
Place some thermostats on the shelves and measure the actual temperature inside the cabinet. Compare the mea-
sured temperature with the value shown on the digital display and adjust the Parameter H12 (see programming
instruction).
Sample.:
Average temperature measured inside the cabinet is: +7 °C, the digital display shows +4 °C,
increase actual value correction by +3.
Sample:
Average temperature measured inside the cabinet is: +3 °C, the digital display shows +5 °C,
decrease actual value correction by -2.
ATTENTION:
Do not measure temperature during defrost mode!
(air temperature will raise up, but product temperature remains unaffected)

How to change the fluorescent light tube
Space inside the stainless steel lights housing is limited - so we recomment to remove the whole lighting fixture
for replacing the fluorescent tube (standard T5 lamps) - see also: Replacment of the lighting fixture on next page.
Caution:
DO NOT service the lights, without isolating the cabinet at the main switch or unplugging it
from the power socket!
Remove the plastic diffu-
sor from the lighting fix-
ture to access the fluore-
scent tube.
Spin the fluorescent tube to see the electrical contacts,
pull away the contacts from each end of the sockets
to release it. Insert the new tube and fix it correctely.
Re-fit the plastic diffusor
and install the ligthing fix-
ture inside the s/s lamp
housing.
TEST:
Turn the power on and test that the lights operate. If normal operation cannot be restord, by changing the
tube, call an electrician.
