The unit I have when I checked the data plate is called Electronic Timer
type ET 20m
1-45 min delay
0-15 sec. on time for bleed.
also has a manual mometary bypass to bleed

The name on the side where purchased is Benz Engineering 800 6984247

I Think there are cheaper units and maybe even Harbor Freight has an electronic one something like this.. This has been in service several years with out a glitch. I tried many of the auto one that react to pressure drop etc. and all plugged and failed for me. In the long run probalby worth the money spent.
