Setting: Air volume when thermostat control is OFF
This setting must correspond with the needs of the user. It
determines the fan speed of the indoor unit during thermostat OFF
condition.

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).
