Abstract:
A method and apparatus for controlling a heater arrangement in a device arranged to heat smokable material is described. The method includes implementing a heater control loop, which control loop performs steps in one or more successive control periods. The control steps include determining a current remaining on time for a heating element of a heater arrangement based on the current rate of change of temperature, a target temperature and a current temperature of a zone of the device arranged to heat smokable material.
