The disclosure relates to the control of trim heaters for preventing the formation of condensation on areas of a refrigerated display cabinet. The power supplied to the trim heaters is varied as a fraction of the maximum power, depending on the ambient temperature and relative humidity. The same fraction of maximum power is applied to multiple trim heaters located in different positions with respect to the refrigerated load and ambient surroundings; these positions have already been taken into account when the maximum power of the trim heaters is set during the design process.
