One more thermostat question on my Harman Accentra after using it for a bit. I set the Accentra control board to 80F and put the thermostat around 68-70 and ignitor in manual mode after startup. When the thermostat calls for heat, the stove burns hot and fast for maybe 10 minutes until the thermostat is satisfied then goes right back to low. Does this put any more heat stress or motor stress on the stove vs letting it modulate from the room probe?
