Resideo L8124G1020 Relay
The Resideo L8124G1020 Relay is a specialized Triple Aquastat Relay designed for forced hydronic heating systems that require high limit protection, low limit control, and circulator management. This immersion-type controller features SPST high and low limit switching to maintain boiler water temperature and ensure efficient domestic hot water service. For multi-zone applications, this unit allows for independent control by using an R845 Relay for each additional zone. The technical design includes a diaphragm powerhead and a Micro Switch assembly that accurately responds to water temperature changes. This Vertical Mount model is built with a large transformer and extra terminals to supply 24 Vac power to low voltage zone valves, simplifying the wiring for complex hydronic heating systems. It features a fixed 10-degree high limit differential and an adjustable 10-25 degree low limit differential, allowing technicians to fine-tune the system for optimal boiler temperature control and circulator performance across an operating humidity range of 0-95% RH.
- Triple Functionality: Integrates high limit, low limit, and circulator control into a single immersion-type unit.
- Precision Switching: Features a 10°F fixed high limit differential and a 10-25°F adjustable low limit differential for tight system temperature regulation.
- Multi-Zone Support: Designed to work with separate circulators and relays, with dedicated terminals for low voltage zone valves.
- Robust Ratings: Capable of handling 120 Vac and 240 Vac loads, with a maximum safe operating pressure of 200 psi on the immersion well.
- Easy Retrofitting: Standard vertical mounting and clear terminal layouts facilitate fast field replacements in residential and commercial boiler sets.
Common Questions
Is the L8124G1020 compatible with multi-zone setups?
Yes, it is specifically engineered for multi-zoning. It includes a larger transformer than standard models to power zone valves and can be combined with R845 relays to manage multiple circulators.
What are the temperature setpoint ranges for this Aquastat?
The high limit operating range is 130-240°F, while the low limit range is adjustable between 110-220°F, making it suitable for a wide variety of hydronic system specifications.
Can this relay be used in high-humidity mechanical rooms?
Correct. The Resideo L8124G1020 is rated for an operating humidity range of 0-95% RH non-condensing, ensuring reliable performance in damp boiler environments.
