Hydrolevel 3250 Fuel Smart HydroStat Temperature Limit Boiler Reset Control

The Hydrolevel 3250 Fuel Smart HydroStat is an advanced three-function control designed specifically for oil-fired boilers. This intelligent control provides temperature limit, boiler reset, and low water cut-off protection, making it a comprehensive solution for modern boiler management and fuel savings.

Key Features:

• Adjustable low and high limits ranging from 110 to 200 degrees Fahrenheit for precise temperature control
• Cold Start or Warm Start operation with Thermal Targeting feature to optimize efficiency
• On-board microprocessor saves fuel by adjusting boiler temperature based on heating demand
• 120 VAC, 60 Hz operation with 7.4 FLA burner contacts
• Easy dial-type setup and dynamic temperature display with LED status lights
• LWCO functionality automatically activated when installed on Electro-Well (sold separately)
• Compatible with optional outdoor sensor kits for outdoor reset and warm weather shutdown
• Uses the same terminal designations as common Aquastat models for easy installation

This control can be installed on existing standard immersion wells for temperature and reset functionality, or paired with a Hydrolevel Electro-Well to enable full low water cut-off protection. The intelligent design monitors heating demand and establishes target boiler temperatures below the high limit setting to conserve fuel while maintaining comfort. Physical dimensions are 3.7 inches wide x 4.6 inches deep x 6.3 inches high.
