The 12-24V supply model of 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. Its low voltage supply suits vehicle applications, mobile equipment, and off-grid temperature control, alongside replacing or upgrading bimetallic and capillary thermostats in machinery and OEM builds.
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.
✅ 3 Year Manufacturer Warranty — backed by our UK-based technical support

Frequently Asked Questions
Why choose the 12-24V version over the mains model?
For vehicle applications, mobile equipment, or off-grid installations where mains power isn't available.
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.
Is there a mains (100-240V) version?
Yes, see the 100-240V N322 PT100.
Industry Applications
- Mobile & Off-Grid Equipment — low voltage supply for vehicle-mounted or remote installations.
- HVAC Retrofit — direct upgrade path from bimetallic or capillary thermostats.
- OEM Machinery — 16A relay drives elements, compressors, or fans without an SSR.
