Resideo L4080B1352 Aquastat Controller 326010-701 signaling the integrated furnace controlThe Resideo L4080B1352 Aquastat Controller is a high limit immersion protective device designed specifically for hydronic heating systems. As a veteran grade boiler control, this unit triggers a break in the electrical circuit upon a temperature rise to the setpoint, preventing overheating by shutting down the burner. It features a technical operating range of 100F to 200F (38C to 93C) with a fixed 8F (4. 4C) differential to ensure stable cycling.
