Information About L8124C1102
The L8124C1102 is a Honeywell aquastat relay engineered to control burner and circulator operation in oil-fired or hydronic boiler systems. It combines adjustable high and low temperature limits with a fixed high-limit differential and adjustable low-limit differential to maintain system temperature stability. The control uses a 3/8 x 2-7/8 in. sensing element installed in a 1/2 or 3/4 in. NPT immersion well for direct boiler water measurement. Designed for 120 VAC systems, it supports thermostat heat anticipator settings of 0.2A and is rated for pressures up to 200 psi when used with an immersion well.
Key Features:
- Triple Aquastat Functionality: Integrates high limit, low limit, and circulator control in one device.
- 120 VAC Operation: Designed for standard 120 VAC, 50/60 Hz hydronic systems.
- Adjustable High Limit: Temperature range 130°F to 240°F with fixed 10°F differential.
- Adjustable Low Limit: Temperature range 110°F to 220°F with 10°F to 25°F differential.
- Immersion Well Sensing: 3/8 x 2-7/8 in. sensing element for direct boiler temperature measurement.
- Pressure Rated Design: 200 psi rating with immersion well installation.
- Flexible Mounting: 1/2 or 3/4 in. taper pipe thread mounting; vertical or horizontal case orientation.
The L8124C1102 delivers the reliability and precision required for hydronic boiler temperature and burner control applications.
