Dehumidifiers:
Depending on the climatic conditions, dehumidifiers
are required. If your system is equipped with dehumid-
ifiers, the limit values for switch-on (relative humidity,
calculated dew point) can be defined in another menu
via the main menu.
The dehumidifiers are assigned to rooms and are
controlled via timer programmes.
Please consult a specialist before making any changes.
The correct setting values of the dehumidifiers ensure
safe operation of the underfloor cooling and also have
a decisive influence on the efficiency of the underfloor
cooling. Inappropriate settings may lead to condensa-
tion on the cooled surfaces and therefore to the risk of
slipping as well as to damage to the surfaces or the
entire components.
IT settings:
Here, settings are made that allow the system to
connect to the Internet for the use of the app.
You can set up the wireless LAN connection to your
router here.
Fig. 06-7 Web page: IT settings
To prevent unauthorised access to your system, it is
imperative to change the system's wireless LAN key
set at the factory.
Network SSID:
Insert WIFI network name of the router.
WPA2-Key of WIFI network:
Insert password (WPA2-Key) of the router.
Insert CA-hash:
If the system's certificate has expired, the CA-hash of
the new certificate must be entered here. The certifi-
cate only expires if the Base has not been online for
several years.
Fan Coils
A fan coil can be assigned to one room to support the
installed system if it has insufficient heating or cooling
capacity.
KNX connection
The KNX connection of the NEA SMART 2.0 system is
suitable for exchanging data (setpoints, actual values,
operating modes and energy levels) between the
NEA SMART 2.0 system and a higher-level KNX
system, e.g. BMS. This connection is made using the
NEA SMART 2.0 KNX gateway that communicates
with the NEA SMART 2.0 system via the SYSBUS. The
assignment between KNX objects and Modbus regis-
ters can be configured using parameters in the ETS
software (license software for KNX). No further soft-
ware is absolutely necessary. The SYSBUS (Modbus)
assignment required for the REHAU NEA SMART 2.0
control system can optionally be imported to the
gateway via DCA (Device Configuration App, SW
extension in the ETS). The SYSBUS (Modbus) assign-
ment can be imported for a KNX installation in the
office or on the construction site.
