Enter the release code and confirm by pressing ENTER; CONTROL re-appears; the setting
to be adjusted now flashes.
Use the UP or DOWN button to set to ON and confirm by pressing ENTER. The message
appears "Data has been saved".
Press the CHANGE button to go to the "MANUAL CONTROL or EXTERNAL" display.
Confirm by pressing ENTER, the term to be adjusted now flashes.
Use the UP or DOWN button to set to EXTERNAL and press the CHANGE button to go to
the input field for the lower output signal x.
Use the UP or DOWN button to set to 0 or 4 mA and press the CHANGE button to go to the
input field for the corresponding % value yy.
Use the UP or DOWN button to set a value > 20% and press the CHANGE button to go to
the input field for the definitive reference value zzz.
Use the UP or DOWN button to set the upper value calculated and confirm by pressing
ENTER. The message appears "Data has been saved".
Press the CHANGE button to go to the SAFETY THRESHOLD display.
Confirm by pressing ENTER, the safety threshold value to be adjusted now flashes.
Use the UP or DOWN button to set the required safety threshold and confirm by pressing
ENTER. The message appears "Data has been saved".
Press the CHANGE button to go to the WARNING THRESHOLD display.
Confirm by pressing ENTER, the warning threshold value to be adjusted now flashes.
Use the UP or DOWN button to set the required warning threshold and confirm by pressing
ENTER. The message appears "Data has been saved".
Use the START/STOP button to re-start the system.
E.g.:
UV treatment is based on operating data for the end of the lifetime of the radiator, which is
indicated by a 50 % radiation output. According to the data sheet, the system is suitable for a
maximum of 200 m
3
/h but is only operated at a maximum of 150 m
allocated to this 150 m
3
/h. The definitive reference value zzz = 60 % x 150 / 200 = 45 %. It
therefore follows from this calculation that there should be a minimum radiation output of zzz' =
50 % x 150/200 = 38 %. The safety threshold is therefore set at -7 [%] and the warning
threshold e.g. at -3 [%]. In this way the radiation output is controlled not only depending on the
radiator weathering but also depending on the flow of water, to achieve a constant dose of
radiation.

Maintenance

The following maintenance work should be carried out at regular intervals:
The UV lamp should be replaced at the end of its useful life.
The protection tube should be cleaned and inspected (usually only necessary when the
lamp is replaced).
The UV sensor should be cleaned (usually only necessary when the lamp is replaced).
Check the wiper mechanism (annually)
Replacement of expendable parts on the wiper mechanism by trained customer service
support (usually every 2 years)
Replacement of wiper mechanism by trained customer service support (usually every
4 years)
The fan filter mats and the air exit filter on the control cabinet should be replaced (usually
once a year).
Keep a log of all maintenance work carried out. There is a template for this in the appendix.
NOTE
The X ring for sealing the wiper drive spindle must be changed at least once every two
years. Any slight leakage which may occur beforehand (slight dripping) will not impair
system performance.
