Re: Device ON reporting - current sensors...

["L Y Chiu" <cytech_tech@xxxxxxxxx>]

The Comfort system has Current sensors which are connected to Comfort
Inputs, see  picture and manual at
http://www.cytech.biz/Default.aspx?cmd=ID%2ftW5Xw2bTCO626ZAAInw%3d%3d&productid=211&categoryid=6&pageindex=

These present a closed contact signal to Comfort when current is
detected in the AC wire.
