1. K4 Schematic Analysis and Pictorial Diagram

2. Turn to page K4 in the Student Handout Packet

3. The pictorial on page K4 does NOT have a schematic for it
The pictorial on page K4 does NOT have a schematic for it. Use information from previous pictorials to figure it out. HINT: the fan control is wired in series with the fan. The transformer primary is hot wired. All of the load controllers at the bottom of the page are wired in the 24v control circuit. Try to complete the pictorial on your own before proceeding. This will be a test to see if you understand series and parallel circuits and how they are used in a pictorial.
