Introduction
Abbreviations / Meanings
Contents Page
Read and follow manufacturer instructions carefully. Follow
all local electrical codes during installation. All wiring must
conform to local and national electrical codes.
Improper wiring or installation may damage the NUI.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety--alert
symbol. DANGER identies the most serious hazards which
will result in severe personal injury or death. WARNING
signies a hazard which could result in personal injury or
death. CAUTION is used to identify unsafe practices which
may result in minor personal injury or product and property
damage.
NOTE is used to highlight suggestions which will result in
enhanced installation, reliability, or operation.
Carrier’s NUI series programmable user interface is wall--
mounted, low--voltage user interface which maintains room
temperature by controlling the operation of a heating and/
or air conditioning system.“Heat pump”,“ Air conditioner”
and“Heat only”are available, with the present versions. A
variety of features are provided including separate heating
and cooling set-points, keypad lockout, backlighting, and
built--in installer test etc. Programming features include
7--day (all days the same), 5/2 (Mon--Fri and Sat--Sun) and
1-day (all 7 days individually) with 2 or 4 or 6 periods per
day.
This Installation Instruction covers installation,
conguration, and startup of NUI. For operational details,
consult the Owner’s Manual.

This selection can be done during installation.
The NUI will be powered with 12V unregulated DCVoltage. This power is supplied to the User Interface by the Air to
Water Heat Pump.
Approximately 5 ft (1.5m) from oor.t
Close to or in a frequently used room, preferably on ant
inside partitioning wall.
On a section of wall without pipes or duct work.t
User Interface should NOT be mounted.
Close to a window, on an outside wall, or next to a doort
leading to the outside.
Exposed to direct light or heat from the sun, a lamp,t
fireplace, or other temperature--radiating objects
which could cause a false reading.
Close to or in direct airflow from supply registers andt
return--air registers.
In areas with poor air circulation, such as behind a doort
or in an alcove.
Turn OFF all power to unit.1.
If an existing User Interface is being replaced:2.

Press the thumb release at the top of the NUI and
snap apart carefully to separate mounting base from
remainder of the NUI.
Route the NUI wires through large hole in mounting4.

ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Before installing User Interface, turn off all power to
equipment.
There may be more than one power to disconnect.

Adjust length and routing of each wire to reach7.
proper terminal and connector block on mounting

Climatic Custom Curves
NOTE:
When NUI is installed (par 100 set to 3) or SUI Comfort mode is installed (par 100 set to 2), control is expecting the choice
between a custom or pre-set climatic curve. In case application requires xed water set point in necessary to set an
horizontal climatic curve by setting par.120=121 for Heating Climatic Curve and 124=125 for Cooling Climatic Curve.
English

Climatic Curves
NUI control adapt calculated water set point to the real
room temperature measured at the user interface point to
keep room temperature stable for comfort and energy
saving.
For this reason actual water temperature can deviate from
calculated water set point by +/- 5°C.
User also can interact with this function by increasing
decreasing water set point by adjusting water temperature
with parameter 4 (see user manual Feature table) as shown
on gure above.

User also can adjust air temperature reading at the user
interface point with parameter 13 (see user manual Feature
table).

Humidity Sensor Failure:
If the sensor used to sense room Humidity reads less than

EEPROM Failure:
If the thermostat non-volatile memory (EEPROM) has failed,
an“E4”error shall be shown in the room air temperature

temperature will be blanked.
“E3”error code will be displayed once and the other

da Carrier, è predisposta per essere applicata al muro,
è un’interfaccia utente a basso voltaggio che regola la
temperatura ambiente tramite il controllo del sistema di
riscaldamento e/o del sistema di condizionamento dell’aria.
Con la presente versione, è possibile la regolazione per

riscaldamento”. Sono previste una varietà di congurazioni
con diversi set-point di temperatura per riscaldamento e
rarescamento, blocco della tastiera, retroilluminazione,
tests integrato, etc....
Le congurazioni di programmazione includono: 7-giorni
