Laars Heating Systems RE2344300 Control Module
The Laars Heating Systems RE2344300 Control Module is a critical PCB Temperature Control Module engineered for precise thermal management in high-efficiency boilers and volume water heaters. Designed to operate at 24 Volts AC (Ā± 10%) at 60 Hz, this module serves as the primary logic board for maintaining setpoint accuracy and system safety. It features a robust single stage relay rated for 4 Amps and integrated pump inducer relays capable of handling 230 Volts AC at 5 Amps (1/3 HP). This configuration ensures seamless synchronization between the burner demand and the circulator pump. Built to meet stringent Class B standards, the RE2344300 offers the reliability required for commercial and residential hydronic applications. Whether you are performing a control board replacement or troubleshooting Laars boiler parts, this OEM module provides exact pin-to-pin compatibility, eliminating the communication errors often found with generic aftermarket universal controllers.
Technical Benefits for Professionals- Electrical Integrity: Rated for 4 VA (192 VA full load), providing stable power distribution to secondary components.
- Integrated Inducer Control: High-capacity 1/3 HP relays specifically designed to handle the inrush current of venter motors and pumps.
- OEM Compatibility: Pre-configured for Laars Mascot and similar high-efficiency series, ensuring correct sequence of operation.
- Environmental Protection: The PCB architecture is designed to resist the thermal stress common in cabinet-mounted boiler electronics.
Is the RE2344300 compatible with older Pennant or Mighty Therm models?
This module is primarily utilized in modern high-efficiency units. Always verify your specific wiring diagram or the version of your integrated boiler control to ensure the pinouts and relay logic match your existing harness.
What are the symptoms of a failing Laars control module?
Technicians often see "No Heat" calls where the inducer fails to kick on or the igniter is not receiving signal despite a closed call for heat. If the 24V supply is confirmed but the relay contacts fail to close, a board replacement is necessary.
Does this module handle the transition from pilot to main burner?
While this PCB manages temperature and pump logic, it works in tandem with the ignition control module to ensure safe light-off and flame supervision throughout the heating cycle.
