RE: [misterhouse-users] safety (was Re: Whole house fan)

[Gray, T. <Gra...@br...>]

First FRS should NEVER be used as any kind of emergency communication.. It
and GMRS (Genreal Radio Mobile Service) are designed for non-reliable
entertainment communication.  control of the HVAC system is non-critical as
the worst thing that can happen is that you die from a hear attack when your
energy bill arrives because it flipped out and kept the house at 90 for 2
days or cranked the AC on and tried to keep the house at 50 while windows
were open.  the only thing bad about X10 controlled HVAC is the remote
possibility of energy costs.. as for the garage door, if your garage door
doesn't have built in emergency stop and sensors it is illegal in the first
place (united states laws)  as for fans... the last whole house fan I seen
installed had a pressure switch that would trip a breaker if it was creating
any significant vaccuum in the house, the other had a paddle above the fan
that if it wasn't detecting airflow then it also tripped the safety and shut
down ..

remember, most of this stuff is designed to deal with the more un-reliable
controller called people...(in fact the most unreliable control system on
the planet is a human being... just look at the idiots that need to be told
not to use their toaster in the bathtub!)

Coffee pots have an auto-shutoff, as does most any appliance.  

safety is important... but in most any NEW equipment and appliances has
added idiot proofing to it that increases the safety margins quite a bit.
