Energon - Fan Coil Digital Controller NR9000/NR9000-RT
1st Issue 09/13 1 DBL408e
APPLICATION AND USE
NR9000 is a digital controller for 2- or 4-pipe terminal units (eg.
Fan Coil) with ON/OFF, 3-POINT oating or modulating con-
trol valves as well as with 3-speed or modulating fan. NR9000
is equipped with MODBUS (SLAVE) communication protocol
enabling the communication with other MODBUS devices (MA-
STER).
NR9000 is composed by a M6 DIN-BAR unit and a ush
mounting remote terminal (NR9000-RT) with integrated room
terminal sensor.
NR9000 and NR9000-RT do not have internal clock manage-
ment. Time schedule must be programmed by a supervisory
system.
TECHNICAL CHARACTERISTICS
Power supply: 85-265Vac (isolated)
Protection Degree: IP 20
Operation temperature: 2T 45 °C
Storage temperature: -25T 65 °C
Dimensions (mm): DIN M6
Inputs:
• Digital Input Window Contact.
• Digital Input Remote Power off.
• Digital Input Winter/Summer Change Over.
• Digital Input Comfort/Economy.
• Analog Input Return Temperature Sensor.*
• Analog Input Remote Temperature Set.*
• Analog Input (S3) Auxiliary loop sensor
• Analog Input (S4) Auxiliary loop set selector
“Remote Power off” or “Comfort/Economy” digital inputs can be
used to interface the controller with a Presence Detector to mi-
nimize costs for heating and cooling.
When digital inputs are in use they have priority on remote sen-
sor and supervisory system.
* Sensors with a sensing element NTC10K Ohm @ 25°C.
Accuracy ± 1K, β @ 25°C = 3435
(reference controlli room sensors S4xxA/B and SNTC-xL)
Digital inputs can be enabled using a conguration tool called
“Conguratore NR9000” thanks to which you can also reverse
the inputs action. It can be downloaded by our web site www.
controlli.eu.
The default status of digital inputs (factory setting) is the fol-
lowing:
DIGITAL INPUT DEFAULT DESCRIPTION
WINDOW CONTACT N.C (normally closed) OPEN – window opened
CLOSE – window closed
REMOTE POWER OFF N.O (normally open) OPEN – Comfort
CLOSE – off (frost protection)
WINTER/SUMMER
CHANGEOVER N.O (normally open) OPEN – winter CLOSE – summer
COMFORT/ECONOMY N.O (normally open) OPEN – Comfort
CLOSE – economy
For example, in case the window switch is normally opened
(closed window is equivalent to open contact) it is necessary to
reverse the action of the digital input.
Outputs:
• 4 TRIAC Outputs to drive 3P valves (HOT valve and COOL
valve). Contact Rating 24..250V 4 A;
• 3 RELAY Outputs to drive 3 speed FAN (V1, V2, V3). Con-
tact Rating 24..250V 8 A;
• 2 Analog Output 0-10V to drive proportional valves. It is
possible to use 0-10V outputs to drive a modulating FAN
plus modulating valves in sequence (0-5/6-10).
• 2 Open Collector Outputs: OC1 and OC2. They have a ma-
ximum load of 18mA and can be used to drive 12Vdc relays
whose maximum power is 220mW and winding resistance
>= 640Ohm (ref. Controlli relay module mod. DGSRMV).
• OC1 output follows the ON/OFF input and it can be
used, through an external relay, to enable electrical
loads. If the local operation mode is enabled (through
controller password) OC1 follows the input DI2 (over-
ride turn off), so if DI2 is open, OC1 is ON too, instead
if DI2 input is closed, OC1 is OFF too. If the local ope-
ration mode is disabled, OC1 follows the value set at
9011 ModBus address.
• OC2 output is used to enable auxiliary functions de-
scribed in the “Controller functions” paragraph. If the
temperture sensor S3 is present, the ON/OFF auxilia-
ry loop which controls OC2 will be automatically ena-
bled; otherwise it is possible to enable the electrical
coil in emergency (through controller password) wich
controls OC2. If the sensor S3 is not present, OC2
follows the value set at 9013 ModBus address.
• Bus to connect Remote Terminal NR9000-RT.
• Bus Modbus to connect Supervisor System.
• Bus Link to connect IO expansion.

OPERATION
The internally stored parameters used by the controller during
operation can be changed using NR9000-RT Remote Sensor
or using a Supervisory System (MODBUS protocol). Remote
Sensor NR9000-RT allows to change the operation mode, the
set point and the fan speed; all other parameters can be modi-
ed only through the supervisory system or the dedicated con-
guration tool. The controller can operate also without the Re-
mote Sensor using a dedicated analog input (Return Sensor).
The controller will take the data coming from the Sensor and
from the Supervisory system (if present) and will perform a P or
PI or PID regulation to drive the valves and the fan.
The controller can operate also without NR9000-RT and su-
pervisory system (Modbus). In this case the room temperatu-
re is measured by the return sensor and thanks to the remote
selector is possible to set the correction of the temperature. In
this conguration, the control parameters can be changed only
through a dedicated conguration tool.
System conguration
The system can be congured as shown in the following dia-

(IO expansion).

Supervisory system
The supervisory system can be implemented using the fol-
lowing MODBUS-RTU (master) devices:
• Operator Panel: MT-NET-PONR: it is possible to connect
up to 50 controllers.
• PC Supervisor: Micronet View or the conguration tool
“Conguratore NR9000” downloadable from www.control-
li.eu site.
• Touch Screen GT series: it is possibile to connect up to 48
controllers
ModBus - RS485 Connection
The RS485 network is implemented with a 3-conductor cable,
which will be later identied as “+” (pin 23), “-” (pin 24) and
“GND” (pin 25). For wiring is suggested Belden ®, model 8762.
For “disturbed” areas is suggested a Belden ®, model 3106A
using the twisted pair to connect the “+” and “-“, the reference
wire to connect to “GND” and the shield to connect to ground.
Alternatively you can use a cable with the following electrical
and mechanical characteristics:
• AWG 20/22;
• characteristic impedance of 120Ω;
• copper wire, “plait” type, twisted;
• shielded braided and insulated;
The shield must be connected to controller GND (pin 25).
1st Issue 09/13 7 DBL408e

ISO 9001
The network must be wired only
in accordance with the principle
shown here, called “daisy chain”
(the device is composed by a sin-
gle RS485 port). Star connections
are not allowed.
Connection warnings
For proper network cabling is recommended to take the fol-
lowing precautions:
1. NOT use different types of cable to achieve the same net-
work, but always use only the same type of cable;
2. The network cable carries out safety voltage signals
(SELV) and must not be wired together with dangerous vol-
tage signals (eg 230V) or carriers of high currents, espe-
cially if in alternating current. Also avoid parallel paths to
these power cables;
3. Wire the cable lying avoiding kinks, narrow bending radii
and unnecessary wrapping in hanks or skeins;
4. Do not twist the cable cord around the power conductors
and, if they should cross, consider an intersection at 90 °
between the cable and these conductors;
5. Keep away from sources of electromagnetic eld in parti-
cular by large motors, electrical cabinet, reactors for neon,
all types of antennas;
6. Do not pull the power cable exceeds 110 N (11.3 kg) to
prevent ironing;
7. Assess in advance the route so that it will be as short as
possible and note addresses of connected instruments with
particular reference to its location in the orderly sequence.
This can be very useful in maintenance; we recommend to
note the Modbus Address on the product label.
Terminating transistors and network polarization
The slew rate control, mutual function in our 485 transceiver
and the limited baud rate to 9600 baud make the terminating
resistors not necessary.
RS485 network needs of polarization typically in charge of the
master device; the controller doesn’t have polarization resistors.
The tranceiver used by the controller allows to drive up to 256
points. RS485 standards require a maximum length of 1200 m
and / or 32 devices on the network.
It should be noted that more limits are exceeded, higher is the
probability that problems in communication arise. The pheno-
menon is not systematic and may not occur. Conversely, in
case you present, and none of the points mentioned in this pa-
ragraph has solved the problem, it is recommended to connect
a repeater (CONV RS485-RIP), as shown in the pictures below:
• Repeater placed where the network exceeds 1200m
• Repeater placed where the network exceeds 32 devices
8. Do not reverse the polarity “+” and “-” of the connection
terminals;
9. Avoid short lengths of cable terminations in connection to-
ols to make a maintenance without tearing or ues of the
cables possible;
10. Identify start and ending terminations and avoid cuts
“open”;

Electrical Coil in “emergency” mode:
Operation modes
NR9000 works with 3 different operation modes:
• COMFORT: the controller will control the temperature (dri-
ving valves and fan) to satisfy the Comfort Temperature
Set.
• ECONOMY: the controller will control the temperature to
satisfy the Economy Temperature Set.
• FROST PROTECTION: the controller is normally OFF; just
during winter operation it works with a set xed at 8°C and
heating function only.
FUNCTIONS
Summer/Winter Changeover
The summer / winter changeover is used by the controller to
reverse the action (Hot / Cold) in 2-pipe systems and to de-
termine whether to add or subtract the temperature correction
in Economy mode. This information can be dened through a
dedicated digital input or via parameter and it can be set by the
supervisory system or by a conguration tool using MODBUS
protocol.
N.B: by default Summer/Winter changeover is set by remote
mode; in stand alone plants it has to be precongured in local
mode;
Initial Valve position
To drive a 3-point actuator is necessary to place the actuator in
a specic position.
Each time the controller is powered up, the actuator will be dri-
ven in the closing position for a time equal to the overall travel
time plus 33%.
Cut-off
This function is used to stop the control of the 3 points actuator
after the overall travel time plus 33%. This function is used to
ensure the correct valve closing and to reduce the noise.
Window contact
This function is used to save energy when a Normally Closed
contact is opened (Open Window). In this case the controller
will change the operation mode from Comfort to Economy.
Hot/Cold launch
This function is used to avoid the introduction of cold or hot air
in the ambient by delaying (for a set time) the fan start.
To disable the function, set the time = 0.
“Disposal”
The “Disposal” function is useful both for the hot and the cold
channel and it helps to take off the energy stored in the fan coil
radiator by delaying the fan turning off.
To disable the function, set the time = 0.
1st Issue 09/13 9 DBL408e
Electrical Coil
Electrical Coil function can be enabled in the conguration tool
as “emergency”.
The output provides an open collector signal (OC2) (with re-
ference to signal pin 30, +12 v) to control an external auxiliary
relay.
The output is activated when the room temperature is lower
than:
“hot” operation set - Proportional Band - 1°C
And it goes off when the room temperature is higher than:
“hot” operation set - proportional band
Auxiliry regulation ON/OFF (P action)
This function can be automatically enable when the sensor in
position S3 is connected. If the remote set in S4 is connected,
it is possible to have a set in the range 10-30°C, otherwise it
can be set through the supervisory system together with the
dead zone.
If the supervisory system is not present , this function will be
carried on at xed point 20°C with dead zone = 1K. The output
will be available in OC2 and it will exclude the management of
the electrical coil.
Air recirculation function
This function manages the minimum fan speed. It is enabled
setting a “period” and a “minimum speed” different from zero.
When the “period” will be passed, the fan will be enabled at the
minimum speed for the time (minutes) set.
Minimum speed activation
This function is used to prevent air stratication, especially
when using the Return Sensor, as it could be very low sensitive
to temperature variation that occurs at man’s height. A conti-
nuous air movement helps to avoid /reduce air stratication and
to optimize the regulation.
A system conguration with Proportional Fan requires setting
the minimum speed in % of the control value (0 - 10V).
To disable this function, set 0 as minimum speed.

ISO 9001
Control modes
NR9000 works with 7 different control modes selectable via dip
switch or by supervisory system:
1. ON/OFF Valves and 3-speed fan (“FAST” operation mode
- Operation Diagram 1).
2. ON/OFF Valves and 3-speed fan (Operation Diagram 2).
3. 3-point Valves and 3-speed fan (Operation Diagram 3).
4. ON/OFF Valves and 1-speed fan (Operation Diagram 4).
5. 3-point Valves and 1-speed fan (Operation Diagram 5).
6. ON/OFF Valves and Modulating FAN (0 – 10 V) (Operation
Diagram 6).
7. 0-5/6-10 Sequence Valves and Modulating FAN (0 – 10 V).
(Operation Diagram 7).
Control modes diagrams
The 0-10V proportional outputs are always presents and they
follow the ON-OFF (or 3-point) valves characteristics.
The diagrams of the valves and fans share the Set point.
To make the interaction of the two devices as exible as pos-
sible the different proportional bands / Hysteresis have been
thought as independent in order to dene a variety of programs
adaptable to different environmental situations.
It is possible to enable the following function with a priority over
normal operation dened by the diagrams:
• HOT/COLD LAUNCH
• “DISPOSAL” FUNCTION
• MINIMUM SPEED ACTIVATION
The valves are activated in ON-
OFF mode with a hysteresis.
Speed 1 is ON when the error
(E) is greater than 10%.

ISO 9001
DIP SWITCHES AND LEDs
The controller has 8 dip switches accessible by removing the
top cover and two leds to check operation anomalies.
Dip switches from 1to 4can be used to set MODBUS devices
address (up to 14) without the use of the conguration tool and
to set the controller in expansion mode duplicating the outputs.
If DIP 1-4 are all ON the controller is congured as expansion,
duplicating the master controller outputs connected to the re-
mote sensor (NR900-RT) and/or to the supervisory system.
If dip switches 1 to 4 are all OFF the default ModBus address is
1 (factory eeprom setting).
In case of more than 14 devices, conguration can be carri-
ed out via supervisory system or using a conguration tool via
Modbus protocol.
Dip from 5to 7are used to select the operation diagram.
If dip 5 to 7 are OFF the default operation diagram is nr. 2 - ON/
OFF Valves and 3 Speed FAN (factory eeprom setting).
Dip 8 is used to select 2/4 pipe system.
If dip 8 is OFF the system is 2 pipe (factory eeprom setting).
Parameters set by dip have the priority over the supervisory sy-
stem. It is possible to disable the dip switch setting by ModBus.
It is necessary to power down and power up the controller in
case of any change in dip switches conguration.

NR9000-RT REMOTE SENSOR
The remote sensor has 4 buttons and a 3 digit display.
The functions of the sensor are:
• Room Temperature Monitoring (T AMB).
• Temperature Set (button 2 & 3).
• Fan Speed Set (Auto, OFF, V1, V2, V3) (button 1).
• Operation Mode Set (Button 4).
The sensor has several congurations (enabled/disabled fun-
ctions) that can be dened by the controller:
• Set Point Disabled
In this case the controller does not allow the user to change
the set point from the Remote Terminal.
• Fan Speed Disabled
In this case the controller does not allow the user to change
the fan speed from the Remote Terminal.
• Operating Mode Disabled
In this case the controller does not allow the user to change
the operation modes from the Remote Terminal.
• Remote Sensor Disabled
In this case the controller does not allow the user to change
all the function listed above and the remote terminal can
show and send to controller only the room temperature.
It is possible to calibrate the room temperature displayed on
the remote sensor of ± 3°C (label tAr) and to read and set the
MODBUS address (label Add) of the controller connected to the
sensor following these instructions:
• press button 4 and reach the off status
• press for more than 10s the button 1 (FAN)
All functionalities are enabled by default.
The remote sensor has a two-coloured led to identify the opera-
tion mode as shown in the following tables:
Operation Mode Led colour
Comfort green
Economy orange
Frost Protection blinking green
