There are a few Types that might help you. The first is a moving
average component (either Type84 or Type939) which calculates the
average value of an input over a certain period of time (for
instance over the last 4 hours). The second is the "input value
delay" (Type93 or Type661 in the TESS Libs). These components hold
on to an input value for a desired number of timesteps before
"releasing" it as an output. There are also some controllers in the
TESS Libraries that have "lock-outs" (the controller must stay on or
off for a certain time after changing state) and another that will
calculate run-time (the time that has elapsed since its input
changed state.)<br>
Best,<br>
