becuase the thermometers in the heaters are crappy if the controller gives the plug power at 77* and the stupid cheep heater says its fine it wont come on and tank keeps getting cooler...................... it would make sense to keep the ehater at a high enough temperature to make sure it would always turn on when the controller plug outlet gets power

The controller is pretty sensitive. In a live rock rubbermaid my RKL is set for 81 and the heater for 83.
It turns on @ 80.9 and off @ 81.1
There is a 'hysterisis' you can set as well. This tells the controller how sensitive to be.
You can program the controller to have a PC4's particular outlet either 'on' or 'off' in the case of a loss of communication ( if say a com cable was to get damaged ).
So you can see the concern if in your case you were to set your heater to 90 with the PC4 to 'on'
