Tried to do this via the PM thing but it appears one cannot attach a file so... We'll go this route. I waded a bit through the posts until the water came up over the tops of my slippers. Gave up and decided to draw a picture of what you needed to end up with. It doesn't matter how you get to where want to be as long as whatever you do doesn't violate the sketch. And you can swap the 120ac for the Neutral on old and new, it doesn't matter as long as you swap both.

OK, so you got me thinking about which wires to cut. I'll try another sketch... I think I could do this with 3 Faston crimp connectors. And by stealing a couple of inches of the hot lead I would have the wire for the jumper from the Imput to Common terminal. The only problem with wiring it this way, is that you miss the opportunity to take the pump load off of the little relay in the control box. If this is a semi-auto, so sweat as the rocker switch is way more robust than a control box relay.

I lied... 4 connectors. If you cut a wire and stuff both ends into the appropriate sized connector you get rid of mid wire splices. Using your Faston connectors as splice points will tidy up your install. Now my slippers are sopping wet.

Thank you .. I THINK I understand this sketch , BUT I dont understand why it would make a difference if the machine is a semi or full auto .. mine works both ways , the machine is the astoria Argenta Junior , it is a automatic machine , with what I would call an over ride on/off brew switch , so I would imagine that the wiring for the brew solenoid is redundant , from the control box or the brew switchjpboyt wrote:OK, so you got me thinking about which wires to cut.

Max - Sure looks to me like the first diagram you posted early this morning: Delay on make relay wiringmaxwerks wrote:I dont quite get that sketch
jpboyt: In that pic, 'C' is the relay NO contact, 'B2' is the relay C contact, and two inputs are labelled 'A' and 'B1'. The 'positive' from 'espresso machine' is the hot wire from the controller that used to go to his pump.
Does it look right to you?

Yes it looks very similar to the first diagram shown here ..although now I am concerned about the " Load "of the pump on the control box ...but it seems that several members have used that same relay I cant imagine they only used it on semi auto machineshomeburrero wrote:Max - Sure looks to me like the first diagram you posted early this morning:

No I take that back .. it is in fact different than my first diagram

This the original older post that I found showing the use of this relay , but I couldnt get an answer from the members who participated in that thread :

Perfectly worded - it will work with the jumpered connection for the live wire, and will be no worse than the original wiring, but it misses an opportunity now that there is that new relay.jpboyt wrote: The only problem with wiring it this way, is that you miss the opportunity to take the pump load off of the little relay in the control box.
If you power the relay switch from a live wire that does not come from the controller, then you will spare having the little relay inside your controller from carrying all the current for the pump - it will only carry the miniscule current that goes through the new relay's input/control circuit. Less current means longer life, and controllers are expensive.
Re auto and semi-auto. On a semi-auto there often is a switch (a button on the lever or a rocker switch) that turns the pump on and off when brewing, and the relay inside the controller may not do much switching. If the controller's relay doesn't do much switching then it's not as prone to wearing out. On an auto, the controller does all switching of the pump.
