Resideo L7248L1105/B Aquastat

The Resideo L7248L1105/B Aquastat is an immersion-style high-limit controller designed for precise hydronic heating system management. This electronic oil boiler control monitors water temperature directly via a boiler well, serving as a critical safety and operational interface for oil or gas-fired units. It functions by cycling the burner to maintain the high limit setpoint while offering an adjustable differential to optimize burner run times and prevent short-cycling. Engineered for both residential and light commercial boiler temperature control, this unit is a standard aquastat replacement for legacy Honeywell systems. The L7248L1105/B features a digital display for real-time diagnostics and local adjustment, ensuring accurate boiler safety limit performance and consistent temperature regulation in retrofit or new installation applications. Its solid-state design eliminates the mechanical drift common in older controllers, providing dependable high-limit protection and burner sequencing for modern hydronic configurations.

Key Benefits:
  • Provides reliable immersion high limit protection to prevent boiler overheating.
  • Compatible with a wide range of oil and gas-fired hydronic heating systems.
  • Electronic temperature sensing offers superior accuracy over traditional mechanical controls.
  • Directly mounts to standard boiler wells for streamlined service and installation.
  • Digital interface allows for precise calibration of setpoints and differentials.
Common Questions:
  • How does the high-limit function operate? The controller monitors the immersion sensor; if water temperature exceeds the setpoint, it breaks the circuit to the burner primary control to prevent equipment damage.
  • Can this replace older Honeywell L8148 or L7224 models? While it serves as a high-limit controller, verify your specific wiring requirements and whether your system requires integrated circulator control before installation.
  • Does this unit support outdoor reset? The L7248L1105/B is a dedicated high-limit control; check compatibility with domestic hot water priority or specialized reset modules if advanced logic is required.
