The Novus N322 PT100 is a digital temperature controller for heating or cooling purposes with 2 independent setpoints, giving 2 relay outputs with independent parameters for direct control of elements, compressors, fans, and valves — no SSR required for simple installation, backed by a 16A relay with Novus reliability. It's a trusted product for replacing or upgrading bimetallic and capillary thermostats, retrofitting HVAC, machinery and OEM builds, and catering equipment.
Operating range is -50 to +300 degrees Celsius. The output control can be refined with adjustable hysteresis and on/off time delays, giving a gentle response with thermostatic control. The N322 will replace or upgrade the majority of manual or programmable thermostats used in industry.

Frequently Asked Questions
Do I need a separate SSR to switch heating/cooling loads?
No — the 16A relay output switches elements, compressors, fans, and valves directly, no SSR required.
What's the difference between the PT100 and J/K/T versions?
The input sensor type — this model offers tighter accuracy (0.7°C) over -50 to 300°C with Pt100; the J/K/T version covers a wider range up to 1000°C.
Can I get this with RS485 for remote monitoring?
Yes — see the RS485 version for Modbus-based remote monitoring.
Industry Applications
- HVAC Retrofit — direct upgrade path from bimetallic or capillary thermostats.
- Precision Process Applications — Pt100 input gives tighter accuracy than thermocouple alternatives.
- OEM Machinery — 16A relay drives elements, compressors, or fans without an SSR.
