NEA SMART 2.0 U-Module
If the U-Module is used for controlling a mixed circuit, then one digital
input can be used to connect a dew point monitor.
Device Function
Dew point monitor A dew point monitor detects condensation
(when U-Module is on pipes or similar. Cooling of all rooms be-
used for mixed circuit longing to the mixed circuit that is control-
control) led by this U-Module is stopped, associated
dehumidifiers (if available) are activated.

Digital Outputs

Digital Outputs can be used to control other devices such as pumps or
boiler. Digital Outputs can be used on the NEA SMART 2.0 Base, NEA
SMART 2.0 R-Module and NEA SMART 2.0 U-Module.
NEA SMART 2.0 Base and R-Module
A maximum of four digital outputs can be configured on a single NEA
SMART 2.0 Base.
Two outputs can be configured for the NEA SMART 2.0 R-Module.
Within a NEA SMART 2.0 Base (and optional R-Module), a function
can only be assigned once. That means, it is not possible to assign
the same function to more than one output.
Reaction
Cooling of this room is stopped, associated dehumidifier is activated.
Cooling of all rooms assigned to the base and to connected R-Module is stopped,
associated dehumidifiers are activated.
Mixed circuit is closed.
Heating / cooling is stopped for 30 minutes.
After this, energy level of this room is switched to REDUCED.
For all rooms assigned to the base and to connected R-module the same measu-
res as described above apply.
System is restricted to operating modes neutral or heating.
The mode heating / cooling (automatic mode) may be activated, but cooling will
not start as long as the input signal HEATING is active.
System is restricted to operating modes neutral or cooling.
Heating / cooling (automatic mode) may be activated, but heating will not start as
long as the input signal COOLING is active.
All rooms 1) which are in TIMER mode go to energy level REDUCED.
All rooms 2) which are in TIMER mode go to energy level REDUCED.
All rooms 3) which are in TIMER mode go to energy level HOLIDAY / ABSENCE.
