Abstract
Operation of an inhalation therapy heater is regulated under control of the temperature sensor for the flow medium to maintain a selected temperature level to which the flow medium is heated during a warm-up period. Operation of the heater is intermittantly interrupted under control of a heater temperature sensor during the warm-up period to minimize temperature overshoot heating. A low temperature detector, disabled during the warm-up period, generates an alarm signal if the flow medium temperature remains below a lower limit at the end of the warm-up period.
