Description
The Honeywell L8124E1016 is a Triple Aquastat Relay engineered for precise hydronic heating system control. Combining high limit, low limit, and circulator relay functions into a single compact unit, this aquastat simplifies boiler control wiring and reduces installation time without sacrificing performance.
High Limit Control
The high limit function protects the boiler from overheating by shutting down the burner when water temperature exceeds the set point. A fixed 10-degree high limit differential ensures consistent, predictable burner cycling.
- High limit operating range: 130–240°F
- Fixed 10-degree high limit differential
- SPST switching action for high limit
Low Limit Control
The low limit function maintains minimum boiler water temperature to ensure domestic hot water availability and system readiness.
- Low limit operating range: 110–220°F
- Adjustable 10–25 degree low limit differential
- SPST switching action for low limit
Triple Aquastat Relay Features
By integrating three control functions — high limit, low limit, and circulator relay — into one device, the L8124E1016 reduces panel complexity and supports reliable, efficient boiler operation.
- Triple aquastat relay: high limit, low limit, and circulator relay in one unit
- 10-degree fixed high limit differential
- 10–25 degree adjustable low limit differential
- SPST switching for both high and low limit
- High limit operating range: 130–240°F
- Low limit operating range: 110–220°F
- Designed for residential and light commercial hydronic heating systems
- Simplifies boiler control wiring with integrated multi-function design
Application
Ideal for use with gas, oil, or electric boilers in forced hot water heating systems. The L8124E1016 is a trusted solution for HVAC professionals seeking reliable aquastat control with simplified installation.
