APPLICAZIONE ED USO
NR9001 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. NR9001 is equipped with
Modbus (SLAVE) communication protocol enabling the communi-
cation with other Modbus devices (MASTER).
NR9001 is also equipped with a second Modbus communication bus
dedicated to communicating with the sensors placed in the envi-
ronment.
NR9001 is composed of an M6 module for DIN rail mounting and can
be equipped with Modbus room sensors STA60M or STA70M.

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. If, on the configurator is enabled "BADGE"
function, the digital input DI4 loses its meaning, while the digital
input DI2 enables the electrical loads and switches the operating
mode between Comfort and Economy.

Summer or Winter on the basis of the fluid temperature and for fan
minimum limit function. As an alternative this function can be asso-
ciated to S3 sensor (if present). S3 sensor is used as minimum limit to
hold the fun if fluid is not warm.
Digital inputs can be enabled using a configuration tool called
"Configuratore NR9001" 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:
DIGITAL INPUT DEFAULT
WINDOW CONTACT N.C.(normally closed)
(4)
REMOTE POWER
N.O.(normally open)
OFF
(4)
WINTER/SUMMER
N.O.(normally open)
CHANGEOVER
COMFORT/
N.O.(normally open)
ECONOMY
(4)
These inputs are disabled by default (except winter/summer
(4)
changeover, look at table page 16). If you need to enable them
a supervisory system is required.
See Badge function

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.
