Speed selection

Set trickle and boost speeds in l/s by using the

To convert m3/h to l/s, divide the m3/h by 3.6 (e.g. 54m3/h / 3.6 = 15 l/s).

The Trickle Speed cannot be higher than the Boost selection. Therefore it might be

necessary to modify the Boost selection before increasing the Trickle setting.

If "0" is selected for the trickle speed, the fan will be off until a boost signal is activated

(for example via LS/ pullcord/humidity).

Boost time

The boost setting allows the boost timer to be adjusted from 1-30 minutes, the default

is 15 minutes. This option may also be disabled, thus removing the option from the

menu and setting the overrun to 0.

Inbuilt Ambient Response Humidistat with Rapid Rise Detection

The humidity threshold setting defines at what relative humidity the fan will trigger,

adjustable from 40% to 90% rH. The fan increases in speed slowly between the trickle

and boost speeds between the trigger %rH and +10%. The trigger point will

automatically adjust if the temperature drops below 18C to prevent nuisance triggering.

The fan also incorporates a rapid rise function to detect rapid rises in humidity when the

ambient %rH is under the threshold setting. If a rapid rise is detected the fan will

increase in speed proportionally between the trickle and boost settings until the

humidity lowers again.

Comfort mode

 With comfort mode disabled, the fan will go into boost as soon as an LS (Light

Switch) input is detected and over-run for the set period after LS is disconnected.

 With comfort mode enabled, the fan will remain off / in trickle up to a maximum of

20 minutes. Once LS is deactivated, fan will run at boost mode for the length of

time LS was present up to a maximum of 20 minutes plus the set over-run time.

If the LS was activated for < 3 minutes, no boost will occur to prevent nuisance

activations.
