Claim Text:
1. A process for controlling a dehumidifying apparatus having a plurality of desiccant modules connected in parallel between a first air distribution assembly connected to a process air inlet, and a second a distribution assembly connected to a process air outlet, the process comprising: setting the first and second air distribution assemblies in a first one of a plurality of discrete positions, for establishing a regeneration air flow between a regeneration air inlet and a regeneration air outlet via a first one of the modules and a process air flow through each of the modules other than the first module; activating (i) a heater associated with the first one of the modules, and (ii) a vacuum unit connected to the regeneration air outlet; determining whether a cycling condition is met; when the determination is affirmative, deactivating the heater and the vacuum unit, and cycling the first and second air distribution assemblies to a second one of the discrete positions, for establishing the regeneration air flow through a next one of the modules and the process air flows through each of the modules other than the next module; and, in response to cycling the first and second air distribution assemblies to the second position, repeating the activating and determining.
