Carrier’s NUI series programmable user interface is a unit /
wall--mounted, low voltage, user interface which maintains
room temperature and domestic hot water temperature by
controlling the operation of a heating / cooling system. A
variety of features are provided including separate heating
and cooling set-points, 2 zone management, domestic hot
water management, keypad lockout, backlighting, and
scheduling for all week days with 2 or 4 or 6 periods.
This manual covers usage, conguration and installation
of NUI.
Note: the NUI will mount the front cover (lid) only in case of wall installation.
Ignore references to lid in case of unit installation.

Programming the Control
Touch‘N’Go feature
Programming the Touch‘N’ Go feature
Selecting the zone
The unique Touch‘N’Go feature on your thermostat is a
revolutionary tool that lets you use a simpler programming
option – literally, touch and go – to help you get the
maximum comfort control from the entire comfort system.
With the touch of one Touch ‘N’ Go button – home
(), away ( ) and sleep ( )–you can tell
your thermostat where you’ll be. To keep the home at that
comfort level indenitely, you add one more button –hold
() – and you’re set. It’s the ideal choice for them whose
schedule varies from day to day or doesn’t t into the
two or four or six predictable time periods allowed by the
thermostat.
At the same time, these three comfort options – home, away
and sleep – are connected to the thermostat’s full-level
programming power so that you get the home comfort you
desire exactly when you want it.
The three Touch‘N’Go buttons are preset at the factory
for typical heating, cooling and domestic hot water
temperature settings and assigned to specic time periods.
You can change these temperature settings and the hours
you want to use them easily. Learn how to do that and
discover how useful this device is as you read through this
manual.
The Touch‘N’Go feature on your thermostat involves home
(), away ( ) and sleep ( ) buttons
immediately under the display. They are used for three
programming options.
The simpler programming option requires you to either
accept the preset temperature settings for when you are
home, away or asleep, or to set your own Touch‘N’Go
heating, cooling and domestic hot water temperature
settings. Either way, your home, away and sleep settings are
automatically linked to one of the time periods that are also
preset (and changeable) on the thermostat.
Here are the temperature settings that are pre-programmed
for your home, away and sleep periods.
To show temperature, humidity, Touch’N’Go settings and
setpoint of a dened zone:
Open the lid1.
Press the zone button (2. ) to select the desired
zone. Zones are indicated as follow
0. NUI zone
1. heating / cooling zone 1
2. heating / cooling zone 2
3. domestic water

Press OK button to conrm changes and exit from the8.
Comfort change mode.
Changing the temperature time periods
After you have set temperature settings for home, away and
sleep, you can program the time of day you want to use for
those temperature settings.
Time ranges are called periods; zone 1 and zone 2 have
maximum 6 periods; zone 3 has maximum 4 periods.
Periods are identied on the display as P1, P2, P3, P4, P5
and P6.
The thermostat has preset periods (see below), but you can
change these to t your lifestyle.
To select the number of periods, refer to the (user)
parameters table in the unit documentation.

Assigning time periods
It is possible to assign the following parameters to each time period.
Zone 1: room temperature ( / / ), Zone mode (ON/OFF), Silent mode (ON/OFF)
Zone 2: room temperature ( / / ), Zone mode (ON/OFF)
Zone 3: domestic hot water temperature ( / ), booster heater (ON/OFF)

The“stop time”for period 1 (P1) is also the“start time”9.
for period 2 (P2). Use the instructions in the next step
to change the start time for period 2.
Press the Touch ‘N’Go button – home (10. ), away
() or sleep ( ) – you want to use during
period 1 (P1) from the row of buttons just below the
display. You will see triangle icon ( ) above the
button selected. This tells the thermostat whether you
are home, away, or sleep during P1. The thermostat
will use the heating and cooling temperature settings
you’ve selected for that Touch ‘N’Go button. For
example, if your heating temperature setting for
home is 23 °C, the thermostat will keep the heat at 23
during P1.

NUI oers a feature where you can add or subtract an oset
to the displayed room temperature. This allows the NUI to
display the correct temperature of the room even if the NUI
or the room temperature sensor is installed at a location
where there is a slight dierence in temperature.
In this case, the TROOM SENSOR ADJ variable can be
modied in a range of +5°C / -5°C and this value will be
mathematically added to the real Room sensor value. Refer
to the parameters table in the main unit documentation.

Installation
Fault Code Table
In case of system failure, the alarm icon ( ) will light up.
Failures are identied by a fault code.
Active fault codes will be displayed in sequence, with a
change rate of 1 second.
Refer to the main unit documentation for a description of
the fault codes.
Safety consideration
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.
Power
The NUI will be powered with 12V unregulated DCVoltage. This power is supplied to the User Interface by the unit to
which is connected.
Step 1 — User Interface Location
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 lidt
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 lidt
or in an alcove.
Turn OFF all power to unit.1.
If an existing User Interface is being replaced:2.
Remove existing User Interface from wall.t
Disconnect wires from existing User Interface,t
one at a time.
As each wire is disconnected, record wiret
color and terminal marking.
Open the NUI (mounting base) to expose mounting3.
