Options:
For manual operation and automatic
Only for manual operation
This parameter is used to specify when the output of the fan speed level values will occur: either
only when the fan speed levels are manually adjusted or also in automatic mode. This setting
depends on the options for the fan coil actuator. If the actuator itself controls the fan speed
levels in automatic mode based on a derivative of the control value, than the "Only for manual
operation" option must be selected. Otherwise, the other option should be selected.
10.24.151
Fan speeds/- levels - Lowest manually adjustable speed-/ level
Options:
Speed level 0
Speed level 1
This parameter is used to preselect the lowest fan speed level that can be set by an operation
performed at the device. When level 0 is selected, the heating/cooling system will not be in
operation (fan speed level and valve control 0) as long as the current operating mode and
operation type are maintained. To avoid damage to the building, level 0 is deactivated after 18
hours and the device is returned to automatic mode.
10.24.152
Fan speeds/- levels Evaluation of fan speed/- level
Options: Deactivated
Activated
The controller obtains the current fan speed level for controlling a fan coil actuator either by
calculating it from the table of level values under "Fan coil settings for heating" or "Fan coil
settings for cooling," or by receiving feedback from the fan coil actuator. If the option is
"activated" here, then the "Fan coil level status" object is activated for receiving the fan speed
level from the fan coil actuator.
