Populated_Pellet_Stove_Controller_Board

Pellet stove controller. Populated PCB.

 

I was constantly burning out my pellet stove ignitor. An external thermostat tends to minimize the temperature fluctuation and causes the stove to run short cycles. The ignitor runs for 20-minutes every cycle.

 

This controller add more hysteresis to the temperature control. It continues to run the stove for a period after the thermostat stops calling for heat. When the thermostat again calls for heat, it adds a delay before starting a new cycle.
