The final equation, Math/Logic 5, is for the stage 2 compressor output. It will essentially a duplicate of the stage
1 equation, but with one additional condition, i.e., the delay timer (math/logic equation 3) must also be expired.
By duplicating the stage 1 equation and appending the requirement that the system 2 delay time has expired
(represented as T5), the stage 2 compressor output will activate and deactivate under the same conditions as
the stage 1 compressor, but also require the system 2 delay to be expired. Since the system 2 delay timer is
only enabled if stage 1 is active and the humidity system is not active, the permits stage 2 operation only when
in heat/cool operation and not humidity operation as required.
Note that this is only an example on how the MCTB and the math/logic module can be utilized to perform more
complex control scenarios such as compressor control. The free-form logic entry provides you with numerous
options and possibilities to implement various logic tasks that your application may require.
