Resideo L8124A1015 Relay
The Resideo L8124A1015 Relay is a heavy-duty triple aquastat relay designed for reliable boiler temperature control and multizone forced hydronic heating applications. Engineering for efficiency, this immersion-type controller integrates high limit protection with low limit and circulator control, ensuring consistent domestic hot water service while protecting the system from overheating. It features an operating humidity range of 0-95% RH and a versatile vertical mount configuration. The high limit differential is fixed at 10°F with an operating range of 130-240°F, while the low limit provides an adjustable 10-25°F differential across a 110-220°F range. This HVAC relay is optimized for use with a 24 VAC thermostat and a 0.2A heat anticipator setting. Built with a 3-inch insulation depth and an included 3-inch immersion well, it provides precise aquastat troubleshooting data via its diaphragm powerhead and Micro Switch assembly, ensuring high-performance boiler management in demanding contractor environments.
Key Benefits- Universal Compatibility: Seamlessly integrates with 120V boilers and is compatible with R845 relays for independent multizone circulator control.
- Precision Thermal Management: Dual temperature ranges and adjustable differentials allow for fine-tuned system cycling and fuel efficiency.
- Contractor-Grade Durability: Rugged immersion controller design includes a grounding screw and high-pressure ratings of 200 psi on the immersion well.
- Flexible Installation: The vertical mount relay design and 3-inch insertion length accommodate standard boiler tappings for rapid field replacement.
- Can I use this for multizone systems? Yes, the L8124A1015 supports multizone control by utilizing an additional circulator and R845 relay for each separate zone.
- Is the high limit differential adjustable? No, this specific model features a fixed 10°F high limit differential to ensure safety-standard thermal cut-offs.
- What wire type is required for terminals? For safe and standard operation, use only copper wiring with the wrap-around terminals provided on the case.
