To set external static pressure by the user interface
Check the indoor unit setting: the value number "—" must be set to
01 for M 11(21) and SW 7.

Field settings are defined as follows:
• M: Mode number – First number: for group of units – Number between brackets: for individual unit
• SW: Setting number
• —: Value number
•
: Default
(2)
Fan speed:
• LL: Low fan speed (set during thermostat OFF)
• L: Low fan speed (set by the user interface)
• Setup volume: The fan speed corresponds to the speed the user has set (low, medium, high) using the fan speed button on the user
interface.
• Monitoring 1, 2: The fan is OFF, but runs for a short time every 6 minutes to detect the room temperature by LL (Monitoring 1) or by L
(Monitoring 2).
