pre-set thermo switch is the controller (w/un-switched power)

The one I have is a dial that I can turn for hotter or cooler fan start. There should be a how to that I did way back when.

The Derale 16738 fan controller (in the picture previously shown) uses the thermostatic probe/sensor/switch (semantics!) as the only on/off control if non-switched power is used to trigger the relay. It is pre-set to turn on at 180F degrees and off at 165F degrees. Non-adjustable.
I want a little more control over the system; using - 1) a switched power/trigger, and
- 2) a manual override switch,
Why? - a) to regulate when and for how long the thermostatic switch is active,
- b) to not let the system run wild and drain the battery, and also
- c) to delay the fan coming on if quicker heat is needed on a very cold day (not really a problem though in Texas, usually).
There's a warning note in the kit's instructions about possibly draining the battery; it's my primary reason for finding an underhood switched power source.
