[Coco] Appliance and Light Controller

[George's Coco Address]

Gene,

  The "Appliance Modules" I have are quite loud. Especially when I live a 
VERY quiet life. That CLACK is quite noticeable and surprising..

 It always surprises me.

 HAH!

 I tried a lamp controller on a relay...... NOT!


 It didn't break the controller, but it didn't work until I paralleled a 
light bulb to the relay, so it would keep current in both halves of the A/C 
cycle and dampen the "turn off" trigger on the scr.

 Bummer, but the lamp was in the water heater closet so, it helped the 
process.

 Conserve, re-use, recycle.
