Resideo L8124E1016 Relay
The Resideo L8124E1016 Triple Aquastat Relay is a reliable immersion-type controller designed for forced hydronic heating systems that require integrated high-limit protection, low-limit control, and circulator staging. This Triple Aquastat Relay is specifically engineered for systems including domestic hot water service, functioning as a central hub to maintain boiler temperature while managing circulator pump operation. It features an operating frequency of 60 Hz and operates on 120 Vac, with SPST high and low limit switching for precise thermal management. The unit provides a 130-240 degree high limit operating range with a fixed 10-degree differential, and a 110-220 degree low limit operating range with an adjustable 10-25 degree differential. Designed for vertical mount applications, the L8124E1016 includes a large transformer and extra terminals to streamline the integration of low-voltage zone valves, ensuring a robust solution for multi-zone hydronic installations. Its diaphragm powerhead and Micro Switch assembly deliver consistent response to internal boiler temperature fluctuations across a 0-95% RH humidity range.
- Triple Functionality: Combines high-limit, low-limit, and circulator control in a single Honeywell Home Aquastat housing to simplify wiring for contractors.
- Zone Valve Integration: Equipped with a high-capacity transformer and extra terminals specifically for powering 24V low voltage zone valves without additional external transformers.
- Durable Construction: Features a rugged vertical mount design with a 1.5-inch insulation depth, rated for pressures up to 200 psi on the immersion well.
- Precise Thermal Control: Adjustable low limit differential (10-25°F) allows for fine-tuning based on the specific recovery needs of the domestic hot water load.
Common Questions
Can the L8124E1016 be used for multi-zone control?
Yes, it is designed for multi-zone hydronic systems. The internal transformer and extra terminals provide the necessary 24 Vac for zone valve operation, while additional zones can be managed by using a separate circulator and R845 relay for each respective zone.
What is the difference between the high and low limit settings?
The high limit acts as a safety to shut down the burner if the boiler exceeds the set temperature (130-240°F). The low limit (110-220°F) maintains a minimum boiler temperature to ensure immediate domestic hot water availability in tankless coil applications.
What thermostat heat anticipator setting should be used?
For proper cycle rates and system accuracy, the thermostat heat anticipator should be set to 0.2 A, plus the current draw of any gas valves connected to the L8124E.
