Description
The Taco Comfort Solutions LFM1203R-1 is a 120-volt Manual/Reset Low Water Cut-Off (LWCO) control designed to protect hot water and steam boilers from the hazards of low-water conditions. Equipped with a built-in test function and a remote probe, this LWCO delivers reliable, code-compliant boiler protection in residential and light commercial hydronic heating systems.
When water drops below the safe operating level, the LFM1203R-1 interrupts the burner circuit, shutting down the boiler to prevent costly heat exchanger damage, dry-firing, and potential system failures. The manual reset design ensures that an operator must physically acknowledge and correct the low-water condition before the boiler is allowed to restart — adding an important layer of safety accountability.
Key Features
- 120V operating voltage for compatibility with standard residential and commercial boiler controls
- Manual/Reset (M/R) operation requires deliberate operator reset after a low-water event
- Built-in test function allows technicians to verify proper LWCO operation without draining the system
- Remote probe design enables flexible installation — probe can be positioned at the correct water level sensing point separate from the control body
- Interrupts burner circuit on low-water detection to prevent dry-fire damage
- Suitable for hot water and steam boiler applications
- Durable construction engineered to Taco Comfort Solutions’ quality standards
