6.7 FROST PROTECTION
The Avenger is equipped with a heat exchanger frost protection algorithm where if the boiler inlet or outlet temperature sensors drop
below 41°F (5°C) the boiler pump is enabled. If the temperature continues to drop to 38°F (3.3°C) the burner will be fired to bring the inlet
and outlet temperatures to 50°F (10°C) to prevent freezing of the heat exchanger.
