By holding the burner above the flame-loss firing point after reignition, the furnace avoids repeated cycling and maintains steady heat.

When a low-fire pressure switch stays open, the controller shifts from low fire to high fire after a preset time to avoid furnace lockout.

Pressure-switch feedback derives blower operating points, cutting furnace calibration time while maintaining safe combustion during transient changes.

Electronic valves adjust primary, secondary, and tertiary air from flue temperature and oxygen data to improve combustion and keep stove glass cleaner.

Variable induction fan speeds during ignition and heating suppress heat exchanger resonance noise while preserving furnace efficiency.

When a low fire pressure switch stays open, the controller shifts the gas furnace to high fire to avoid lockout and reduce downtime.

NTU sensing before washing estimates laundry soil level, then adjusts wash time, detergent dose, and rinses to cut water and agent waste.

Balancing fan speed and combustion amount across connected heaters reduces exhaust pressure differences and prevents burner combustion failure.

Controlled secondary air mixing re-burns combustible gases in a woodstove, cutting particulate emissions without catalytic converters.
