INTRODUCTION
N323R is a temperature controller suitable for refrigeration. It has
functions specially designed for temperature control and defrost
optimization applications.
The equipment has two input channels for temperature sensors (NTC
thermistor type) that measure the temperature of the monitored
environment and the evaporator module. In addition, it has three
independent outputs for controlling the compressor (refrigeration
output), the defrost module and the fan.
The features of each controller are identified on the identification
label, attached to the equipment, and are in accordance with the
purchase order.

SPECIFICATIONS
PROBE INPUT:
2 Thermistor NTC
Type 10 kΩ @ 25 °C
Range: -50 to 120 °C (-58 to 248°F)
Accuracy: 0.6 °C (1.1 °F)
Note: The sensors come with the equipment.
Its operating range is limited to -30 to +105 °C (–222 to +221 °F). It
has cable of 3 m in length, 2 x 0.5 mm², and can be extended up to
200 meters.
Maximum error in the interchangeability of original NTC sensors:
0.75 °C (33.35 °F). This error can be eliminated through the Offset
parameter of the equipment.
Measurement resolution: ........................... 0,1° from -19.9 to 119.9°
......................................................................................... 1° elsewhere
Note: The equipment keeps its precision all over the range, despite
the lack of display resolution in a part of the range does not allow its
visualization.
