Fan unit ELS EC..
m
Only an authorised electrician may change the settings!
Before opening the cover:
After fully isolating the unit from the power supply and removing the spiral from the casing, wait 3 min. until the connec-
tion cover can be opened.
Material damage due to touching electronic parts!
The unit electronics can be destroyed by a static discharge.
►Observe protection against electrostatic charges, e.g. protective gown, conductive footwear and/or wrist strap.
►Do not touch open contacts!
1. Automatic humidity control system
The humidity control system always controls the required ventilation or the highest stage for multi-speed types. The
microprocessor-controlled electronics detect two different types of humidity increase in the room air. It distinguishes
between a slow and rapid humidity increase.
– High air humidity (slow humidity increase)
In case of a slow humidity increase (e.g. due to washing, drying textiles, temperature reduction), the fan will be activated
above the set room humidity of 70 % RH (factory setting) and it will run until the room humidity has fallen by approx. 10
%, but at least for the set 15 minute overrun time.
– Event control (rapid humidity increase)
In case of a rapid humidity increase (e.g. due to showering, bathing), the fan will be activated before the set activation
threshold of 70 % RH is reached to eliminate the excessive humidity in the room as effectively as possible and to quickly
restore the comfort zone (40-70 % RH) in the room. As soon as the relative humidity has fallen to approx. 60 % RH
(factory setting), the fan will be deactivated, but no earlier than after the set overrun time of 15 minutes.
2. 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 be cancelled when actuated.
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 be cancelled when actuated.
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.
5.0 Cleaning
m
The safety instructions specified in section 1.2 must be observed!
Material damage due to touching electronic parts!
The unit electronics can be destroyed by a static discharge.
►Only carry out functional test with mounted facade.
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
