• 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
