U-Module 24 V
The U-Module 24 V is a universal extension module for
the base. Depending on the configuration, it can be
used to control the flow temperature, actuate up to 2
dehumidifiers or actuate an extraction fan as required.
Remote sensor
The temperature sensor is connected to the room unit
and can be configured for floor temperature moni-
toring in heating and cooling applications or for meas-
uring room temperature.
Flow/return sensor
Temperature sensor is connected to the
NEA SMART 2.0 U-Module to measure the flow and
return temperature of a mixed heating circuit.
Outdoor sensor
The wireless outdoor sensor measures the external
temperature and is located on an outer wall of the
building. The outdoor sensor is assigned to a
NEA SMART 2.0 Base.
Antenna
The antenna serves as an option to increase the range
of the wireless signal to the room units. The antenna is
connected to the base and is installed outside the
heating circuit manifold box.
KNX Gateway
The KNX gateway enables data transmission from the
NEA SMART 2.0 control technology to a KNX system.
Values such as: setpoints, actual values, operating
modes and energy levels can be exchanged with a
higher-level KNX system such as a BMS.
