4.9. Clean Mode
The clean mode is used to interrupt regular
operations of the controller when the room is
empty. When this mode is enabled, the con-
troller closes all tunnel doors and curtains and
then only provides a minimum level of heat
and ventilation (optional). If minimum ventila-
tion is used in the clean mode, all inlets will
open to their respective minimum ventilation
position; otherwise they remain closed. The
letters
“CLn”
are shown on the LED display
when the clean mode is active.
Cleaning the room:
A soaking output can be
activated to clean up the room. If this output
is used, soaking cycles automatically start
when the clean mode is on. Refer to chapter
11 of this manual to get further information
about the soaking output.
Clean mode set point:
In clean mode, fans
that are used to provide minimum ventilation
and heaters operate according to the clean
mode set point: heaters turn on when the
room temperature is lower than the clean
mode set point and fans turn on when the
temperature is higher than the set point.
Refer to section 5.1 to adjust the clean mode
set point.
Low temperature alarm:
The controller can
sound an alarm if the temperature gets too
low while the controller is in clean mode. Re-
fer to section 12.3 to set this alarm limit.
