That looks like an easy way to build in some preinfusion on my Faema. It looks like the timed relays are all 24 or 120V, I need 220 rated at about 5 amps, the only 240 rated unit I see is only 1amp at 120v. I will have to dig around McMaster and see if I can find one of these gems.

I'm sure the mfr. makes the same part in 240v; I'm still in France (fly back tomorrow) and have no access to my stuff, but as I recall the mfr. is National Controls Corporation. If Rick can supply you with the actual mfr. part no., you can call them for the part number you would need (or check their website; I forget how complete it is). I did call them for tech support at one point (on a similar timer that I never could get to work on my machine) and I was able to speak with a human being in tech support.

I think this is a great, low cost, upgrade that anyone with a non-preinfusing rotary pump should consider trying.

Ken has it right -- the supplier is "National Controls Corporation", 1725 Western Drive West, Chicago IL 60185.

See their site at http://www.natcon.com/

The box the relay came in lists a phone number of 800-323-2593. The model # is QIT-00010-341. It is the 0.5 to 10 Second 120 VAC model, and has a number 0609 on the label.

It shows up here, and there doesn't seem to be a 240V model:

However, there's another model that does come in 240V, althought I don't know if it would do the same job:

It looks like it is only rated for 1A. I need to check the amps on the pump. It does not draw many amps, but I believe it is over 1A.

Most of the timed relays I have seen require a mounting base, the spade fitting on this one would make the connection quick and simple.

I'd be shocked if NCC doesn't make the same relay in 240v; the fact that a particular US based supplier may not carry it is an altogether different matter.

Note that if you get one of the (large number of) iterations of these timers without an onboard relay, you are likely not going to be able to get it to work without also installing a separate relay as part of the circuit. I tried every possible way of wiring one of those timers (without a built in relay) and never could get it to work more than one time; I'd have to unplug the machine from power in order to get it to work one more time, after which again it would stop working. The supplier of the first relay, which I never did get to work, was Allied, and they carried scads of different NCC models but not the one I found on Mcmaster.com , with built in relay, which is the one that ultimately did work on my machine.

The 120V relay I installed is rated for 8 amps.

Thanks for the info. I put a call into them yesterday. I got a VM back but have not had time to call back. Job is getting in the way.

These timed relays are available from any well-stocked HVAC parts supplier. It is common in HVAC installs to delay the start of the condenser fan motor a few seconds or so after the compressor kicks in.

Hi all,
A while ago, my beloved WEGA Lyra's vibe pump started leaking. I sent it away to Espressoparts for some surgery. Among other smaller mods, I requested an upgrade to a rotary pump. I asked TerryZ about the preinfusion delay that was discussed in Ken & Jim's research, and Terry indicated that it was unnecessary due to the "E60.5" preinfusion characteristics. He claims that even though the WEGA version of the E61 does not include the ability to start the water flow without turning on the pump, the internal plumbing of the "E60.5" group has a natural preinfusion which allows the pressure to slowly ramp up regardless of whether a vibe or a rotary pump is pushing the water through the machine. Terry is arguably the leading expert on the WEGA machines, so I don't have any reason to doubt him.

I should receive the machine by Friday, so I will post here if I find any major differences between using the vibe pump and the rotary.

Rick - the side effect of a quieter boiler refill is quite alluring. I might have to get your help on adding in the relay, as I am severely challenged when it comes to working on electrical stuff.
