The controller has an AH unit running time counter. Enter the counter's alarm limit
at which the controller requests maintainance of the AH unit. The alarm is shut off
by raising the maintenance limit or by resetting the AH unit counter (see p. 6). If
the setting is ”0”, the maintenance alarm is not in use.

The controller starts up the AH unit to ½ or minimum output when the CO
content rises 100 ppm above the CO "Minimum" value given here. The controller
shuts down the AH unit when the CO content has been below the CO "Minimum"
value for the post-running time.
The controller switches the AH unit to 1/1 output (maximum output),when the CO
content rises to the CO "Maximum" value given here. The controller switches the
AH unit output to ½ (minimum output), when the CO content has been 200 ppm
below the CO "Maximum" value for the post-running time.
Attention! AC inverter AH units: stepless AH unit control according to the CO
content.

Damper control according to CO2 content. (see p. 33):
The dampers begin to open from the "Damper min. "
position when the CO content has risen above the
CO "Minimum" value.
The dampers open to the "Damper max." position
when the CO content has risen above the CO
"Maximum" value.

AH unit post-running time:
When the CO content control switches the AH unit
from maximum control to minimum control or shuts down the AH unit from
minimum control, the change occurs after the CO post-running time. This
prevents the AH unit from switching too soon from one operating mode to the next
when the CO content changes quickly.
