Requirements on the assembly site 2.1.2
The heat recovery unit is suitable for being mounted in frost-free interior areas. The indoor-climate
ambient conditions must not permanently exceed 70 % r. F. at 22 °C.
Frost protection 2.1.3
The NOVUS is equipped with automatic frost protection which prevents that the heat exchanger freezes
at very low outside air temperatures. Depending on the set frost protection mode, the fans are temporarily
switched off when falling below the threshold values of the device intake air limit temperature. With regard
to the NOVUS-series with integrated defroster, a PTC heater battery is activated when falling below the
threshold values of the device outside air limit temperature. However, if it is fallen below the threshold
values despite the heat quantity supplied by the integrated defroster, the fans are temporarily switched off
as well.
The automatic frost protection for monitoring the supply air temperature serves as freezing protection of
an optional downstream hydraulic heater battery and temporarily switches off the fans when falling below
the threshold values of the limit temperature for the supply air.
Joint operation with heat-producing appliances 2.1.4
In case of simultaneous operation with heat-producing appliances, e.g. chimneys, the corresponding
standards and regulations must be complied with by the qualified personnel. The joint operation of indoor
air-dependant heat-producing appliances and ventilation plants requires an appropriate safety device
(differential pressure switch) or a plant-specific measure, in the event that dangerous negative pressures
can be generated in the installation room of the heat-producing appliance during operation. The NOVUS
is set up for the joint operation with heat-producing appliances.
Available control modules 2.2
The NOVUS can be equipped with the following control panels:
•
Control unit LED control panel (w x h x d in mm: 80 x 80 x 12)
•
Control unit TFT touch panel (w x h x d in mm: 102 x 78 x 14)
•
External boost ventilation switch (any number, potential-free)
•
External sensors with sensor signal 0-10 V or 4-20 mA
The ventilation device can be operated with up to 3 control units type TFT touch panel or
without control panel. A TFT touch panel is recommended for commissioning!
These control modules are explained in more detail in the following sections.
LED control panel 2.2.1
The LED control panel has 7 symbolized short-stroke keys. By pressing a key or key combination, the
corresponding operations are performed. The active mode of operation is signaled by means green or red
LED.
