Modine 3H0368490001 Time Delay Relay Board

The Modine 3H0368490001 Time Delay Relay Board controls your HVAC system's precise timing. This electrical conductor synchronizes the operation of parts such as fan motors, making sure they continue to function for a predetermined amount of time even after the primary signal is cut off. Consider of it as an integrated stop button that guards against sudden shutdowns and protects hardware from deterioration. This board, which is commonly found in HVAC units and Modine heaters, uses complex circuitry to delay electrical signals for a predetermined amount of time. The delay is essential for a number of reasons, including clearing trapped combustion gases when the burner turns off, avoiding cold drafts by keeping the fan going for a little while after the heating ceases, and shielding sensitive parts from abrupt on/off cycles.
