    Isnt your power switch already a 3-position switch? Off-Autofill ON-All on

    Make sure SW2 is hooked up to the correct position on SW1.

    Re PI a delay timer on the pump is worth considering that would also allow line pressure to do the PI.

    Send me the Electrical diag..I will try to have a look.
    I only have access to the expanded view of the mechanical parts for now
    I will ask Barazi to email me the Electrical Diagram if available and pass it on to you

    There is only a BZ35 Electrical Diag on there site

    Would need to see the cct..Depending on how they do things.. Can mean a simple solution ior a bit of a fiddle.But either way... You have space inside  
    So that means I can entice you with free coffee AM   ;D

    Edit: Also entice you with Greek sweets we just made for Easter

    TWO switches.Off - ON

    Linked, so that Switch 1 is Element 1 and Switch 2 is element 2... But Switch two is linked to Switch 1.
    Will a similar switch like the one you are planing to use on the Della Corte work ?

    e.g. keep the current on off switch and use the new switch for the elements

    You could just disconnect one of the elements KK.... Thats what a lot of owners do  8-)

    Mal.  
    I contemplated this Mal before I put in a dedicated 15 amp power line
    I still want it to heat up quick

    However the next best thing may be a 3 way switch

    OFF
    ON with both elements working
    ON with one element working


    KK
    NO... Not so simple grass hopper..

    TWO switches. Off - ON

    Linked, so that Switch 1 is Element 1 and Switch 2 is element 2... But Switch two is linked to Switch 1.

    Thus configure is:

    Sw1 = Off (All OFF)

    Sw2 = ON or Off = OFF

    Sw1 = On = One element

    Sw2 = Off = One element

    Sw2 = ON = Two elements

    KK on a side note, update ya sig, youve got ya little beauty now

    maybe contact PIDKits KK, jims a top bloke who will not hesitate in giving advice on alternate applications.....

    Re: PID with pre infusion

    Sounds like you need to install something like a bypass solenoid to let mains pressure do the preinfusion
    OK forget this, I found the thread I was looking for and it doesnt involve adding a bypass solenoid rather it sounds like it just involves opening the brew solenoid to allow line pressure through before the pump starts, but dont take my interpretation as gospel the babelfish is hard to comprehend.

    I love this machine but with the 2 x 1450Watt elements it needs to be tamed

    Can i ask.....why KK, why do you want pre-infusion and a PID on your boiler? or is it simply for bling?
    I am looking at PIDs for practical reasons
    I love this machine but with the 2 x 1450Watt elements it needs to be tamed
    with a PID for home use

    As for the bling - thats where the blue lights come in

    I may ask Bezzera if the PID from the BZ07 can be fitted to the BZ40 with a little wiring change

    [edit]Sorry ill clarify a bit, just out of interest, have you done any temp testing on your brew water? just wondering what the current variation is in boiler temp.....

    That being said, i love PIDS and SSRs ;D so cool![/edit]

    Re: PID with pre infusion

    With the Auber PI the 3 way solenoid opens when the pump pauses, so no pressure builds up, it doesnt really PI it can only wet the puck or excess pressure just vents out through the 3 way.
    I went into PI when I modified the Silvia and ended up fitting a solenoid/OPV arrangement I find it works quite well, in your case you just need a bypass solenoid though I have no idea how to work it in with the volumetrics.
