Description
The Warrick-Gems Sensors & Controls DFL1A0Z040406 is a professional-grade dual function liquid level control engineered for dependable operation in demanding HVAC, boiler, and hydronic system applications. Combining dual-function level sensing with a manual reset mechanism and built-in time delay, this control delivers superior protection against nuisance trips and system damage caused by improper fluid levels.
Product Overview
Warrick-Gems Sensors & Controls is a trusted name in conductance-based liquid level sensing. The DFL1A0Z040406 is designed to monitor and control liquid levels across two independent functions — typically high-level and low-level cutoff — within a single compact unit. The manual reset feature ensures that after a fault condition is detected, an operator must deliberately reset the control before the system can resume operation, adding a critical layer of safety oversight. The integrated time delay helps filter out momentary level fluctuations, preventing false alarms and unnecessary shutdowns.
Key Features
- Dual function liquid level control in a single unit
- Manual reset required after fault — enhances operational safety
- Built-in time delay to prevent nuisance tripping from transient level changes
- Conductance-based sensing technology for reliable, low-maintenance operation
- Compact design suitable for boilers, condensate systems, and hydronic applications
- Manufactured by Warrick-Gems Sensors & Controls — an industry-trusted brand
Typical Applications
- Commercial and industrial boiler low-water cutoff protection
- Hydronic heating system level monitoring
- Condensate management and overflow protection
- HVAC equipment requiring dual-point liquid level control
Why Choose the DFL1A0Z040406
The combination of dual-function control, manual reset, and time delay in a single device simplifies installation, reduces panel space requirements, and provides multi-layered protection for critical HVAC and boiler systems. The manual reset function ensures technicians verify system conditions before restarting, reducing the risk of equipment damage from recurring faults. The time delay feature adds stability by ignoring brief, non-critical level variations that could otherwise cause unnecessary system shutdowns.
