Controlli NR9000 Manual

Energon - Fan Coil Digital Controller
APPLICATION AND USE
NR9000 is a digital controller for 2- or 4-pipe terminal units (eg.
Fan Coil) with ON/OFF, 3-POINT floating 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 flush
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.

"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 configuration tool called
"Configuratore 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
WINDOW CONTACT N.C (normally closed)
REMOTE POWER OFF N.O (normally open)
WINTER/SUMMER
N.O (normally open)
CHANGEOVER
COMFORT/ECONOMY N.O (normally open)
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.
Terminals:
Pluggable terminals (J1 & J2) 5 mm pitch for low voltage si-
gnals (230VAC) and 3,5 mm pitch (J3 & J4) for very low voltage
signals.
Look at the table on the next page for details.
Directive and Standards:
Standard CEI EN 60730-1 for EMC directive.
Standard CEI EN 60730-1 and CEI EN 60730-2-9 for LVD di-
rective.
INSTALLATION
NR9000 are suitable for mounting on a DIN rail with a quick
coupling; NR9000-RT is suitable for wall mounting or flush
mounting in A503 electrical Box with B-TICINO (Living & Light)
and VIMAR (Plana & Idea) finishing plates.
Connections shall be in compliance with existing rules and
using max 2,5mm cross section wires for J1 and J2 terminals
2
and 1,5mm cross section wires for J3 and J4.
2
To use wire terminals on power supply wires follow the instruc-
tions in order to prevent accidental contacts between cables at
different voltages in case of wrong installation.
