SPEED SETTING
The control system enables equal speed settings or synchronous speed correcting for the supply and extract fan (see
ALL
).
If the air resistance differential in the supply and extract air ducts the speed of the supply and extract fan can be individually adjusted and
this setting will be saved in the controller memory (see
SPL
and
Eht
, respectively).
The controller circuit board has a digital indicator and
«KEY1»
,
«KEY2»
,
«KEY3»
buttons which are used for operation mode setup and
editing of the operation parameters. After switching on power the ventilation unit operates normally and the light indicator is off. Press

«KEY2»
and
«KEY3»
. The display shows the current
setting of the menu item:
•
«ALL»
: actual speed setting for both the supply and extract fans over the range from 0 % up to 100 % (displayed as previously set
speed setting for the supply fan). For example, in case of activated
LOW
-speed mode, editing of this parameter will result in change
of the low speed setting both for the supply and extract fans. To display or change this parameter press
«KEY1»
and set a required
value using the buttons
«KEY2»
and
«KEY3»
. Then press
«KEY1»
to save the value in the nonvolatile memory and return to the setup
menu.
•
«SPL»
: activated speed setting of the supply fan displayed percentagewise over the range from 0 % to 100 %. For example, in case of
activated MEDIUM-speed mode, editing of this parameter will result in change of the supply fan MEDIUM speed setting. To display or
change this parameter press
«KEY1»
and set a required value using the buttons
«KEY2»
and
«KEY3»
. Then press
«KEY1»
to save the
value in the nonvolatile memory and return to the setup menu.

: activated speed setting of the extract fan displayed percentagewise over the range from 0 % to 100 %. For example, in case of
activated HIGH-speed mode, editing of this parameter will result in change of the HIGH speed setting for the extract fan. To display or
change this parameter press
«KEY1»
and set a required value using the buttons
«KEY2»
and
«KEY3»
. Then press «
