Because oil is very expensive I want to know how much oil I use every cold season and how much poorer I am. Also how much oil have to order for next cold season!
Need some parts as:
- Plastic box
- converter 230Vac to 12Vdc
- 12Vdc hour counter
As you can see all parts and converter are inside the box
Counter calculate how many 220Vac 1/10 hour sycles is there on pin B4 (see drawing) . Very simple system…!!
