Hydrolevel 3150 120V Hydrostat Universal Temperature Limit and Low Water Cut-Off for Oil Fired Boilers

The Hydrolevel 3150 is a 120-volt hydrostat that provides dual safety protection for oil-fired boilers by combining both temperature limit control and low water cut-off functionality in a single universal unit. This combination control helps prevent dangerous overheating conditions while also protecting the boiler from operating with insufficient water levels, which can cause costly damage or system failure.

Key Features:

• Dual-function design combines temperature limit and low water cut-off protection
• 120-volt operation for standard residential and light commercial applications
• Universal design fits most oil-fired boiler installations
• Automatic shut-off prevents boiler operation when water level drops below safe threshold
• Temperature limit control prevents overheating conditions
• Reliable probe-based water level sensing technology

This hydrostat is designed for straightforward installation on oil-fired heating systems and provides essential safety protection to extend boiler life and prevent hazardous operating conditions. The low water cut-off feature ensures the burner will not fire when water levels are inadequate, while the temperature limit function provides an additional layer of protection against excessive heat buildup.
