Fan Unit ELS-V..
Installation and Operating Instructions
Runtime limiter
In cases with constant, excessive amount of humidity, the fan will be automatically deactivated after two hours, e.g. if
the incoming air is above the set relative humidity of 70 % (e.g. in case of a stormy atmosphere in the summer or if there
is constantly damp laundry in the room) or in case of an insufficient air exchange rate due to small-scale or blocked air
vent openings.
In this respect, there are two possible stop times depending on the situation:
a. Short stop time
The humidity has fallen below the activation threshold by the end of the overrun limit, but it has not yet reached the
deactivation threshold. The fan will then be deactivated, the short stop time of one hour will run.
Background: There was a humidity reduction during fan operation. However, the reduction was not enough to fall
below the deactivation threshold. A short stop time will be activated, because it is assumed that the humidity can be
effectively reduced after short break. Any humidity measurements are ignored during the stop time.
→
The required ventilation stages can still be operated. The stop time will continue to run in the background. Only
mains deactivation and activation can delete the stop time.
b. Long stop time
The humidity has not fallen below the activation threshold by the end of the overrun limit. The fan will then be deactiva-
ted, the long stop time of six hours will run.
Background: Since the humidity value has not fallen below the activation threshold, it can be assumed that further
ventilation makes no sense. A long stop time will be activated. Any humidity measurements are ignored during the stop
time.
→
The required ventilation stages can still be operated. The stop time will continue to run in the background. Only
mains deactivation and activation can delete the stop time.
A balance between minimised energy consumption and optimal humidity reduction is achieved with the-
se humidity curve control functions. Damp surfaces due to condensation and the associated risk
of mould formation and unpleasant odours are largely avoided.
4.5 Test mode
(function 4.1 to 4.4)
When there is no voltage present (power failure, fuse, etc.), the ELS-V.. is in the test mode for 1 minute. If the factory
settings have been changed, normal operation will activate straight away.
When test mode is running, the fan can be activated without start-up delay using the switch input for demand-control-
led ventilation (always the highest stage for multi-speed units). When deactivating demand-controlled ventilation in the
test minute, the fan will immediately switch off without overrun. This applies for a switch cycle within the test minute.
The activation and deactivation of demand-controlled ventilation within the test period will end the test period with the
deactivation of demand-controlled ventilation. If the switch input remains activated beyond the test minute, the fan will
continue to run until the switch input is deactivated and the subsequent overrun time is finished.
The humidity sensor (function 4.4) remains active in test mode, but only works as “push button” during the test minute
(humidity activation threshold reached
→
immediately on, level falls below humidity activation threshold
→
immediately
off).
The aforementioned conditions shall apply, as with demand-controlled ventilation.
5.0 Cleaning
m
The safety instructions specified in section 1.2 must be observed!
– Clean the facade, protection grille and visible casing parts with a damp cloth and warm soapy water if necessary!
– Do not use aggressive cleaning agents that could damage the paintwork!
– High-pressure cleaners or jet water is not permitted!
5.1 User maintenance
The fan unit has an extremely large-scale permanent filter with a high dirt absorption capacity for long cleaning intervals.
The permanent filter must be cleaned and undergo a status test at certain time intervals e.g. semi-annually (depending
on the level of contamination). A contaminated filter will cause a significant reduction in performance and can cause the
overheating and thus failure of the unit.
The filter can be cleaned with warm water or in the dishwasher up to 60 °C (
). Allow to dry properly after cleaning.
In case of damage, the permanent filter must be replaced with a new filter.
Spare filters can be ordered online at www.ersatzluftfilter.de
– Filter cleaning indicator
(Fig.1)
The filter cleaning indicator in the facade indicates the level of contamination of the permanent filter and the
associated reduction in performance via the red check point.
