This ignition control relay regulates the burner sequence of operations, ensuring precise timing for safe startup and flame monitoring in your hydronic system. Designed specifically for Lochinvar heating units, the 100093847 ignition control board maintains consistent performance to prevent lockout conditions and system downtime.
The module functions by processing inputs from safety limit switches and temperature sensors to initiate the igniter and prove flame presence via the flame rod signal. If the sensing logic fails to detect a valid flame within the prescribed safety window, the control immediately shuts off the gas valve to maintain operational integrity.
Key System Performance Baselines:
- Flame Detection: Precise millivolt sensitivity for immediate response to burner status changes.
- Safety Interlocks: Integrated monitoring of limit circuits to prevent unsafe ignition cycles.
- Energy Efficiency: Optimized cycling parameters designed to reduce wear on gas valve actuators.
⚠️ Application Profile: Primarily installed in Lochinvar commercial boilers and high-efficiency water heaters requiring direct spark or hot surface ignition control.
