Resideo L8124L1011 Relay

The Resideo L8124L1011 is a professional-grade Triple Aquastat Relay designed for immersion-type control in forced hydronic heating systems. This horizontal-mount controller integrates high limit protection with low limit and circulator control, making it a standard for maintaining boiler temperatures and managing domestic hot water service. It features SPST high limit and low limit switching with a fixed 10°F high limit differential and an adjustable 10-25°F low limit differential. For multi-zone applications, this aquastat controller allows for seamless integration with separate circulators and R845 relays. The unit operates with a high limit range of 130-240°F and a low limit range of 110-220°F, ensuring precise thermal management. Built with a diaphragm powerhead and Micro Switch assembly, the Honeywell L8124L1011 responds rapidly to temperature fluctuations. Designed for 120V or 240V line voltage applications, this boiler temperature control relay is the technician's choice for reliable hydronic system regulation.

Key Benefits
  • Integrated Control: Combines high limit, low limit, and circulator switching into a single Triple Aquastat Relay housing to streamline boiler wiring.
  • Zone Flexibility: Easily provides multi-zone control in hydronic systems when paired with additional circulators and relays.
  • Robust Switching: Utilizes SPST switching action rated for 7.4A at 120 Vac, suitable for standard burner and circulator loads.
  • Precision Sensing: Features a 3/8-inch diameter sensing element for accurate boiler water temperature monitoring up to 265°F.
  • Environmental Resilience: Operates effectively in high-humidity environments with a 0-95% RH non-condensing range.
Common Questions
  • What is the difference between the high and low limit on the L8124L1011? The high limit breaks the burner circuit if the temperature exceeds the setpoint (130-240°F range). The low limit maintains a minimum boiler temperature for domestic hot water, with an adjustable differential of 10-25°F.
  • Can this relay be mounted vertically? No, this specific model is designed for horizontal mount applications to ensure internal components and the diaphragm powerhead function according to factory specifications.
  • Is an immersion well included with this part? Typically, the L8124L1011 is sold as the controller only. A compatible immersion well must be ordered separately if one is not already installed on the boiler tapping.
