Condition to activate signal
A room assigned to this base or a connected R-module has a current demand
signal (heating or cooling)
R-module triggers the "hydraulic" valve (only in cooling mode)
Any room of the entire installation has a current demand signal (heating or cooling)
or
Demand signal for mixed circuit has been generated
Any room of the entire installation not supplied via a mixed circuit triggers a hea-
ting demand signal
more than the pre-defined amount/level
Same as above, but for cooling demand signal
System is in heating mode. Can be used to control valves or to signal this conditi-
on to other devices or to a BMS
Same as above, but for cooling
Dehumidification sequence started. Valve opens before compressor starts.
Dehumidification started
error signal
Function
The pump of the mixed circuit is star-
ted according to the demand.
The hydraulic valve, that is connec-
ted to supply water to the dehumidi-
fier, is opened according to the de-
mand signal.
The compressor of the dehumidifier,
is started according to the demand
signal.
or
a dehumidifier allocated to the base or connected
any of the dehumidifier triggers the "hydraulic" valve (only in cooling mode)
or any of the mixed circuits causes the mixing valve to open by

Internet Connection

Although an internet connection is not required to run the NEA
SMART 2.0 system, a connection is recommended to benefit from the
following advantages:
- full control of the system even when not at home
- get latest software version via over-the-air-updates (OTA)
- have access to detailed evaluations of temperatures, humidity, flow
temperature reports, ...
- Advanced functions such as geofencing are possible only when
connected to the internet.
The connection to the internet can be done
- Via WIFI network (2,4 GHz)
- Via Ethernet cable.
The recommended option is via cable as WIFI may not be available at
the place of installation, e.g. basement.
The manual assignment of IP address and respective
subnet is not supported on device itself, however, NEA
acts as an DHCP client. Therefore NEA can be used only within
the Networks with running instance of DHCP server.
In more complex installations with more than one NEA SMART 2.0
Bases, only the master base station requires an internet connection.
