You need someone to come in and trace the wiring if you cannot figure it out. You said you had the Paragon wiring diagram already, if not the link below can be used.

This defrost time can be used for both hot gas and electric heater defrosting so check to see which defrost type is being used.

SOURCE: I need a wiring diagram

Paragon 8145-20 is a 240VAC (2 phase) timer. I doubt you will be able to find a 3 phase type timer.

I would suggest you use this timer as a control and purchase either contactors or relays rated to handle the 3 phase load.

How to set the defrost duration on a timer


Copy following link for defrost timers:
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

There are 2 general types defrost timers.
Time activated - Time terminated
Time activated - Temperature-pressure terminated, with timed termination back-up

Here is basic image:
http://waterheatertimer.org/images/8145-work-image.jpg
Rotate dial until current time lines up with pointer, insert tripper pin on outside edge of dial to select defrost start-time, move defrost duration tripper on inner dial to set termination time.

Each defrost timer is slightly different:
If timer is time-terminated, then wiring follows certain diagram.
If timer is temperature-pressure terminated, then different wiring diagram is used.

I need a three phase wiring diagram for 8145-20 model timer.


8145-20 240Volt Paragon timer is not 3-phase.
Clock motor is 240V.
You need a transformer to convert 3-phase to single phase 240V to operate timer.
Then timer outputs can control 3-phase power using 3-phase contactors
Contactor below is 3 phase with 240V coil

Defrost timer wiring diagrams show below:

I have a paragon 8145-20 defrost timer. do you wire the compressor to the timer? I cant seem to find a wiring diagram on how to wire this correctly


Link below has wiring diagrams and wiring manuals for 240V 8145-20
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

I am not expert installing defrost timers.
According to information from Paragon, 8145 is for hot gas defrosting. 8140 series are time initiated, and pressure-or-temperature terminated.
Wiring diagram does not show compressor wired to timer.

The cycle works like this:
Timer is running but defrost is not switched ON.
Fan is ON.
Timer switches ON and activates defrost cycle.
Fan turns OFF. Hot gas valve turns ON for defrosting.
Cycle limit switch is temperature or pressure sensitive.
Cycle limit switch reaches trip point, timer switches OFF.
Hot gas valve turns OFF. Fan turns ON.
So fan is off during defrost cycle.
Hot gas valve turns ON when timer switches ON.
Timer is switched OFF by pressure-or-temperature limit switch.
