Resideo L8124C1003 Relay
The Resideo L8124C1003 Relay is a heavy-duty, immersion-type Triple Aquastat Relay engineered for professionals managing forced hydronic heating systems. This Honeywell Home L8124C1003 unit provides precise integration of high-limit protection, low-limit control, and circulator operation, making it a reliable solution for oil-fired boilers and domestic hot water applications. Designed for a horizontal mount, it features a 130°F to 240°F high-limit range with a 10°F fixed differential, alongside a 110°F to 220°F low-limit range with an adjustable 10°F to 25°F differential. This boiler temperature controller utilizes a diaphragm powerhead and Micro Switch assembly to respond rapidly to temperature fluctuations. For multi-zone installations, this aquastat relay supports expanded control when paired with additional R845 relays. Built to withstand demanding mechanical rooms, it operates within 0-95% RH and handles line voltage switching up to 7.4A at 120 Vac. This 120V aquastat is the standard for contractors requiring dependable hydronic heating controls with SPST switching action and a 1-1/2 inch insulation depth.
Key Benefits- Comprehensive Boiler Control: Consolidates high limit, low limit, and circulator functions into a single immersion-type controller for streamlined wiring.
- Precise Thermal Response: The 10° fixed high limit differential ensures consistent safety cut-offs, while the adjustable low limit allows for fine-tuned domestic hot water production.
- Zone Expansion Ready: Easily integrated into multi-zone hydronic systems using separate circulators and relays for customized heating circuits.
- Rugged Electrical Specs: Rated for 7.4 FLA at 120 Vac, providing the current capacity needed for standard burner and circulator motors.
Is the L8124C1003 compatible with vertical mounting?
No, this specific model is designed for horizontal mount applications. For vertical installations, a different L8124 model should be selected to ensure proper operation of the diaphragm powerhead.
Can this relay be used with gas-fired boilers?
While typically optimized for oil-fired systems, it can be applied to hydronic systems requiring triple function control; however, contractors should verify the millivolt or 24V requirements of the gas valve.
What is the maximum pressure rating for the sensing element?
The unit supports up to 200 psi when used with an immersion well, or 100 psi if the capsule is inserted directly into the boiler water.
