COMMISSIONING
Advanced feature descriptions
If compatible, the unit can be controlled via the Bluetooth linked App. This is only available on
X
units.
Comfort mode
If Comfort mode is enabled the unit will behave as follows to all LS inputs:
Trigger
Action
LS input active less than 5 minutes
No action
LS input active more than 5 minutes but less
than 20 minutes
Once LS input is removed, fan will run at user
selected speed for the length of time LS was
present plus the set over-run time (if over run is
enabled).
LS input active more the 20 minutes
Unit will Boost after 20mins.
Once LS input is removed, fan will run at user
selected speed for 20 minutes plus the set over-
run time (if over run is enabled).
The above applies to all LS inputs. The times are not adjustable by the user.
Humidity
– Rapid rise
Rapid Rise humidity response functions to detect rapid rises in humidity when the ambient %RH is under the threshold
setting. If a rapid rise is detected the fan will boost until the humidity lowers again.
Humidity
– Ambient response
When ambient response is enabled the threshold set point is modified based on the ambient temperature. This helps
to prevent nuisance boosting of the unit as temperatures changes during the day.
Analogue inputs
Both analogue inputs have adjustable low and high trigger voltages within the 0-10V range.
The response to being above or below either of the threshold voltages is user settable.
The display
doesn’t show a decimal point, for example at threshold voltage of 5.2V, is displayed as “52” on
the unit.
Unit adjustment
1. Commissioning and configuration on all products is supported by the 3 digit user interface and
associated push buttons.
2. When powered on, the unit will display the firmware revision number, after a few seconds the unit
will display the first option in the menu structure (see below).
3. Changes to the settings can be made
via the
+
and
–
buttons, the Menu button will
accept changes and move onto the next menu option.
4. When setting the speeds, there is an internal logic: low<Normal<Boost<Purge.
I.e., Boost is always higher than Normal.
5. The actions for each of the Live Switched (LS), inputs are selectable. The setting for delays and
over run timers are applicable to all inputs.
