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). Contact Rat
-
ing 24..250V 8 A;
•
2 Analogue Output 0-10V to drive proportional valves. It is possi
-
ble to use 0-10V outputs to drive a modulating FAN plus modu
-
lating valves in sequence (0-5/6-10);
•
2 Open Collector Outputs: OC1 and OC2. They have a max
-
imum 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);
•
the OC1 output has a different management depending
on whether the Badge function is enabled or not. In both
cases they are handled electrical loads. If Badge function
is enabled, the OC1 output goes ON when the badge is
inserted into the “pocket” (DI2 = closed). When pulling out
the badge (DI2 = open) the OC1 output goes to OFF after
30 sec. If the badge is disabled, OC1 output follows the
ON/OFF input and it can be used, through an external re-
lay, to enable electrical loads. If the local operation mode
is enabled (through controller password) OC1 follows the
input DI2 (override turn off), so if DI2 is open, OC1 is ON too,
instead if DI2 input is closed, OC1 is OFF too. If the local
operation mode is disabled, OC1 follows the value set at
9011 ModBus address;
•
OC2 output is used to enable auxiliary functions described
in the “Controller functions” paragraph. If the temperature
sensor S3 is present and “loop Aux” function is enable, the
ON/OFF auxiliary loop which controls OC2 will be automat-
ically enabled; otherwise it is possible to enable the electri-
cal coil in emergency (through controller password) which
controls OC2. If the sensor S3 is not present, OC2 follows the
value set at 9013 ModBus address;
•
1 BUS output for Modbus supervisor connection;
•
1 BUS output for STA60M or STA70M sensor connection.

Directives and Standards
Standard CEI EN 61326-1 for EMC directive.
Standard CEI EN 61010-1 and CEI EN 60730-2-9 for LVD directive.
INSTALLATION
Installation of NR9001 controller
NR9001 are suitable for mounting on a DIN rail with a quick coupling.
Connections shall be in compliance with existing rules and using max
2,5 mm
2
cross section wires for J1 and J2 terminals and 1,5 mm
2
cross
section wires for J3 and J4.
To use wire terminals on power supply wires follow the instructions in
order to prevent accidental contacts between cables at different
voltages in case of wrong installation.
The main power is fully isolated but we suggest to install a protection
device compliant to existing national rules with a 125 mA interven
-
tion threshold and a minimum 3mm contact opening. The device is
not supplied with the product.
Installation STA60M sensor
STA60M room sensor is suitable depending on the model:
- for wall mounting;
- for flush mounting (65x40 mm round box).
For further information refer to the mounting instructions (NR9001_
DIM298.pdf)
Installation STA70M sensor
STA70M room sensor is suitable for wall mounting.
For further information refer to the assembly instructions (NR9001_
DIM298.pdf)
MAINTENANCE
The product is maintenance-free.
TERMINAL
STA60M
STA70M
NR9001 terminals
NOTE: the maximum distance of the connection cable to the control-
ler must not exceed 15 meters.
For wiring we recommend the Belden® cable, model 8762.
The controller is equipped with removable 5.08 mm pitch terminals
(J1 and J2) for low voltage (230V) and 3.5 mm pitch (J3 and J4) si
-
gnals for very low voltage signals.
