LOW VOLTAGE

Schematicto

Pictorial

You will now draw the

Pictorial

by following the

Schematic

The process will be to follow the

schematic one wire at a time from one

component to another component until

you are finished.

The slides that follow will show the wire in RED on

the schematic that is going to be wired on the

pictorial. Then the pictorial slide will show that

wire being ‘installed.’ This is the wire you are to

place on your pictorial. Keep advancing through

this slide presentation until you are finished with

the pictorial.

Before you begin to wire any low voltage circuit, you need to identify the

low voltage ‘POWER’ side and ‘COMMON’ side of the transformer.

The ‘POWER’ side is ALWAYS the side that goes to the identified terminal

on the thermostat. In this diagram it is the ‘V’ terminal. This is for ITT,

which is no longer used. It will be the ‘R’ terminal instead of this ‘V.’ See

below where I have identified the ‘POWER’ side and the ‘COMMON’

side of the transformer. Now move onto the next slide and complete the

pictorial.

P C

Since there are two yellow wires, you need to

identify which one is ‘P’ and ‘C’ or you will

wire the unit incorrectly. It does not matter

which one is ‘P’ or ‘C.’ See below.

You have finished the

circuit.

The next slide shows your completed

and this is what you need to show

your Instructor for credit.
