Abstract
A heater includes a heating unit that supports at least a high-power state, a low-power state and a stand-by state. A control circuitry of the heater implements a state machine to control the heating unit, with respective states in the state machine corresponding to power states in the heating unit. The transition from a first state to a second state in the state machine is determined by a comparison between a measured ambient temperature with a predetermined threshold temperature for transitioning from the first state to the second state.
