The Novus N322 J/K/T 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, catering equipment, and commercial ovens.
Operating range is -50 to +1000 degrees Celsius with a K-type thermocouple (see technical details below for J and T ranges). 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.
✅ 3 Year Manufacturer Warranty — backed by our UK-based technical support

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 J/K/T and PT100 versions?
The input sensor type — this model reads J/K/T thermocouples (wide range up to 1000°C with K type); the PT100 version offers tighter accuracy over a -50 to 300°C range.
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.
- Commercial Ovens & Catering Equipment — wide thermocouple range and independent dual setpoints.
- OEM Machinery — 16A relay drives elements, compressors, or fans without an SSR.
