N320 Model: Digital electronic thermometer that indicates
measured temperature values. Offset adjustment.
!
N321/N322/N323 Models: Thermostat with one, two or three
relay outputs. They can be configured through keypad for
heating or cooling control. They all feature a relay output for
control, N322 has also an alarm output and N323 has two alarm
outputs. The alarm output can be configured as minimum,
maximum or differential alarm.
Example: Multi-stage HVAC systems.
!
N321R Model: Automatically defrosts by interrupting the
compressor activity with programmable time interval and
manual defrost key. Holds indication while the defrosting cycle
is performing. Application example: Chambers and frozen food
displays.
!
N322T Model: Thermostat with two relay outputs. It features a
relay output for control and a relay with timed triggering for use
in enforced defrosting, agitation and other applications that
require periodic triggering. It is employed in HVAC systems.
Example: Milk coolers and heating pumps.
!
N322RHT Model: Digital controller for relative humidity and
temperature. It features two relay outputs for control that can
be separately configured as control or alarm.
Example: Fruit storage and air conditioning.
!
N323R Model: Thermostat that controls the end of defrosting
by temperature. It features three output relays: compressor,
defrosting and fan. Operates with two sensors (NTC), one for
room temperature and other to be attached to the evaporator
for control of defrost end. Employed in cooling and defrosting.
Example: Frozen chambers and displays.
!
LED indicators 3 ½ digits.
!
Sensor offset adjustment.
!
Adjustable hysteresis.
!
Minimum and maximum range for configurable setpoints.
!
Configuration is maintained even with energy failures.
!
Configurable password for configuration lock.
!
Long life silicone keys.
!
CE and UL Certified. (USA and Canada).
OPTIONAL:
!
RS485 interface with Modbus RTU protocol.
!
Power supply: 12 to 24 Vcc.
