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
controller only provides a minimum level of
heat and ventilation (optional). If minimum
ventilation is used in the clean mode, the
air inlet will open to its respective minimum
ventilation position; otherwise it will remain
closed.
Cleaning the room: A soaking output can be
used to clean up the room. If this output is
enabled, it will automatically start running
according to a user-defined timer at clean
mode startup. Refer to chapter 8 on page
32 to get further information about the
soaking output.
Clean mode set point: During the clean mode,
the fans that are used to provide minimum
ventilation and the heaters operate accord-
ing to the clean mode set point: the heaters
turn on when the room temperature is lower
than the clean mode set point and fans turn
on when temperature is higher than this set
point.
Low temperature alarm: The controller can
sound an alarm if temperature gets too low
while being in clean mode. Refer to section
12.1.3 to set this alarm limit.
