Engineering position
Three-output heating and cooling temperature controller for heating, refrigeration or HVAC sequences
The controller coordinates temperature or humidity measurement with compressor, heating, defrost, fan, alarm or auxiliary functions. Output count alone is not sufficient for selection; sensor version, control sequence, electrical ratings, supply and communication options must also match the refrigeration or HVAC design. Three-output ON/OFF temperature controller for applications requiring three independently configured setpoints/control-alarm functions.
Heating or refrigeration actionConfirm direct/reverse action, hysteresis and load ratings for the heating or cooling duty.
Setpoint and alarm configurationDefine independent setpoints, alarms and auxiliary output functions before commissioning.
Panel control integrationMatch sensor version, relay allocation, supply and optional communication to the panel schematic.
Current product position: Current N321/N322/N323 documentation treats the sensor input as an ordered product version—NTC, Pt100 or J/K/T—not as one universal input.
System role
N323 signal and system architecture
The architecture separates the field/process interface, the NOVUS function and the downstream control or information path. Exact electrical interfaces, protocol roles and accessories remain model-dependent.

Use the current NOVUS product page, manual and exact order code as the final authority for numeric ratings, approvals, firmware-dependent functions and supplied accessories.
Application scope
N323 application environments
These application classes indicate the engineering context. Final selection still depends on the exact range, I/O, communication, installation and performance requirements.
Refrigerated cabinets
For refrigerated cabinets, confirm the sensor version, output allocation and control sequence before assigning compressor, heating, defrost, fan or alarm functions.
HVAC temperature loops
For hvac temperature loops, confirm the sensor version, output allocation and control sequence before assigning compressor, heating, defrost, fan or alarm functions.
