- 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
- Compatible with both temperature probe and thermal sensor setups
