6.3 Adjustment of stop level
The stop level can always be adjusted in the following way:
1. Change the snore margin (window 12) and perform a new Auto set. The
new stop level will be set in relation to the snore margin. See examples in
Fig. 2, page 11 and Fig. 3, page 12.
2. Change the stop level directly in window 11.
6.4 Start conditions and pause time
adjustment
In normal operation there are two starting options:
1. Pump start after remaining pause time (window 01).
2. Pump start at high level switch (window 53 = “1”). This requires connection
of a high-level switch according to Section 6.1.5, page 29.
The pump will also start if a non-latched alarm disappears or the button is
pressed during pause.
Calculation of pause time is based on previous pumping and pause times and is
controlled by the two parameters, level setting (window 21), and maximum
