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 control valves as
well as with 3-speed or modulating fan. NR9000 is equipped with
MODBUS (SLAVE) communication protocol enabling the communi-
cation with other MODBUS devices (MASTER).
NR9000 is composed by a M6 DIN rail unit and a remote terminal
(NR9000-RT) with integrated room terminal sensor. It is possible to use
the NR9000-TC remote control (optional) to set a daily switching on
and switching off; time table control can be carried out through the
supervisory system too.
NR9000-RT is the remote terminal which can be connected to the
controller (further details on page 16).
NR9000 can be connected to a receiver module (NR9000-RX, techni
-
cal characteristics on page 18) and controlled by a infrared remote
control (NR9000-TC, technical characteristics on page 17).

*”Remote Power off” or “Comfort/Economy” digital inputs can be
used to interface the controller with a Presence Detector to mini-
mize costs for heating and cooling.
When digital inputs are in use they have priority on remote sensor
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 in
-
puts action. It can be downloaded by our web site www.controlli.eu.
The default status of digital inputs (factory setting) is the following:

These inputs are disabled by default because of the controller status word
(look at table page 15). If you need to enable them a supervisory system
is required.
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.
