Subject: Remapping Giemme to Gicar on ECM giotto?
 

I just received a replacement for the relay box on my giotto - and it's different on the new Gicar from the old Giemme.  I'm wondering if any lurkers here might have some insight for how to hook up the new unit.  I am cross posting here from HB since it seems to be secret knowledge... ;-)  Original article, with pictures, is on HB  here:


Well... I'm trying to replace. I replaced dead unit last year, and that's dead (judging from the same behavior I'm dealing with again). The replacement I got last year is labeled 'giemme' and the new one is a 'gicar'. One of the relays in the giemme is dated 12/99 and the gicar board has a date inside of 06/05 - and now the posts for the wiring look different. Can anyone help out? I figured the #8 on the black label was ground (green wire / unshielded terminal). The thin blue wire went from #10 black (giemme) to F9 on the white (gicar)label, which was 'serb' on both. I then assumed the thin clear conductor 's.liv.' (giemme) was = 'cald' (gicar). The rest I'm hosed on. Can anyone help me out? What I have is:

Gicar
F1 - F
F2 - C.Carichi and N
F3 - Res RL1
F4 - Ev Cald RL2
F5 - Pompa RL2
F6 - Abil Erog
F7 - (ground, I think)
F8 - Cald
F9 - Serb

Giemme
Well... just check out the picture. If you guys have any ideas of what wire should go where, let me know! I did find one reference to some of the info from another site:

---------
EG -- electrovalve grupo -- > group brew solenoid
RE -- resistence electrico (or something like that) -- > heating
element
AE -- alimentare electrovalve -- > boiler fill solenoid
MP -- motor pompa -- > pump motor
L -- dunno (ground/earth, maybe?)
--------

Therefore, my guess is that (old giemme to new gicar) should go something like:
#6 resistenza to F3 res RL1
#7 gruppo to F6 abil erog .... and that's about all I would hazard a guess at.

OK - I think I got it - if anyone sees a mistake, let me know before my house burns down.  Just to summarize what I found:

Therefore (giemme on left, gicar on right):
gruppo = abil erog
P = pompa RL2
ev liv = ev cald RL2
resistenza = res RL1
L = c.carichi
1 = F

Other side of the box (the 3 connectors):
Serb = serb (at least that was easy (blue wire)
Ground = ground  (green wire)
S.Liv = cald  (clear wire)
