Abstract:
1. A control module for influencing a test environment parameter of a single incubation system, comprising: a control command interface unit configured to receive at least one control command, said control command interface unit configured to couple with a bus; a control device coupled with said control command interface unit and configured to influence the test-environment parameter based upon said at least one control command; a further interface unit coupled to said control command interface unit and configured to output again, from said control module, in identical form said at least one control command that has been received; an air outlet emitting air to be conducted into a test environment; an air inlet receiving the air to be conducted into the test environment; a conduit communicating air from said air inlet to said air outlet; and a housing having sides, said air inlet and said air outlet being disposed on opposing ones of said sides to enable stacking of said control module with another control module such that said control module, together with the other control module, is operable to influence different test environment parameters by influencing the same air flow, said control command interface being disposed on one of said opposing sides on which one of said air inlet and air outlet are provided, and said further interface unit being disposed on the other one of said opposing sides on which one of said air inlet and said air outlet are provided, one of said control command interface and said further interface unit being disposed on the opposing side having said air outlet from which air influenced as a result of the at least one control command is emitted.
