<P class=MsoPlainText>Dear Trnsys-colleague,<o:p></o:p></P>
<P class=MsoPlainText>It is unbelievable but I have spend more than one hour
on that and still doesn't work...the point is:<o:p></o:p></P>
<P class=MsoPlainText> <o:p></o:p></P>
<P class=MsoPlainText>I would like to switch off a signal when the difference
between the High Temp (fix to 22 ) and Low Temp is less than 0 and switch on
again when the difference is higher than 1.5..are you able to do
that?<o:p></o:p></P>
<P class=MsoPlainText> <o:p></o:p></P>
<P class=MsoPlainText>At the moment in my deck (attached) it seems that
instead off an hysteresis loop I have just a value limit 1.5 where is ON and
OFF around it!!!<o:p></o:p></P>
<P class=MsoPlainText> <o:p></o:p></P>
<P class=MsoPlainText>Thanks a lot and suggestions are well
accepted<o:p></o:p></P>
