Functions and Features

3.4.1

Room temperature control (surface heating/cooling)

Room temperatures are controlled by the valves in the manifold being
opened at specified times, respective of the temperature recorded by
the room units and the target temperature (pulsewidth modulation
process – PWM).
A suitable set of parameters is selected for the chosen heating/cooling
system, such as underfloor heating, ceiling heating or cooling
systems.
It is possible to use different heating/cooling systems in one room at
the same time without using auxiliary components, such as relay
circuits or gate valves upstream of the manifolds.
3.4.2

Room temperature control optimisation functions

The NEA SMART 2.0 control system permanently
analyses the temperature sequences in individual rooms
and then optimises the control mode. Such optimisation
provides maximum comfort while ensuring ideal energy
efficiency:
- Compensation can aid comfort controls
- Detection of temperature drop in heating mode, e.g. due to
open window
- Extremely precise compliance with the target values thanks to
automatic adaptation of control parameters
- Auto boost function to ensure prompt return from reduced mode
3.4.3

Hybrid technology (bus/wireless), pairing of room units

The NEA SMART 2.0 Base offers the option of communicating with
wired (bus technology) room units and wireless room units as standard.
Room units can be easily and reliably registered on the individual base
channels (pairing). The process is identical for both technologies.
3.4.4

Integrated WLAN/LAN, operation via browser or app

The NEA SMART 2.0 Base has WLAN/LAN as well as a web server
standard „on board". Systems used purely to control temperature
(with a base) can be set up and operated using a standard web
browser.
There is a user app available to end users featuring a series of
easy-to-use functions to operate the system inside the house and
while away from home. This app also offers analysis and maintenance
information in a separate section for installer.
