What’s New
- Improved Display & Layout
- Larger, clearer LED display with °C / °F units
- LED repositioned for better visibility
- All wiring relocated to the rear for cleaner, easier installation
- Faster Dual Fan Operation
- Second fan start-up delay reduced to 5 seconds for improved cooling response
- Advanced Override Control
- Dual manual override wires for independent fan control
- Selectable override signal polarity (positive or negative)
- Enhanced Durability
- Upgraded to IP67 rating for superior water and dust protection
- Expanded Temperature Range
- Adjustable from 5°C to 110°C (41°F to 230°F)
Key Features
- Digital temperature control with easy push-button adjustment
- Dual relay outputs for independent fan operation
- Automatic fan staging for efficient cooling
- Memory retention of temperature settings
- Designed for direct coolant measurement using included M12 x 1.5 thermal sensor
- Suitable for 12V systems (24V compatible with relay change, part #10534, sold separately)
How It Works
- Fan 1 activates at your set temperature
- Fan 2 activates 5 seconds later for staged cooling
- Both fans switch off once temperature drops 5°C below set point
Installation Flexibility
- Direct coolant measurement via included M12 x 1.5 sensor (ideal for thermostat housing, radiator, engine block or inline adapter)
- Radiator probe mounting or direct coolant measurement options
- Inline adapter compatibility for hose installation
- Simple wiring with clearly labelled connections (battery, ignition, fan outputs, overrides)
(Refer to installation diagrams and wiring layout shown on page 3 of the instructions for full setup guidance.)
