Hi, first I gotta excuse myself for this bunch of noobish questions I've been bugging you with last weeks :D :D
Now..next question: does it harm the compressor if I switch it off and immediately on again ? That's because my Abit is giving me a hard time booting up and I often need to switch my rig off and turn it on again. Anyways I think I'll run the prommy seperately, because it always gets hotter than 40°C while bootup.

Try unplugging/plugging in your fridge for a week and come back and tell me when it is unusable and doesn't cool down anymore.

I'm not talking of a week, more like a sec. or even less

Yes it will damage the compressor. You should run the Mach from seperate PSU so it wont shut down even if your mobo boots.

Btw i have a question about compressor taking harm...

Is it ok to have a compressor stading on the side just before turning it upright and then turn it on ??

I heard that you have to leave it standing for an hour or so.

Farbor, what is that thing??
Do you have a link to that system?

I'm confused, if you're supposed to run the Prommi non-stop, without it turning off and on again, why is no mention made of this in the manual, and why does my GT have a failsafe feature built in that makes you wait 2 minutes after shutdown before it will power back up again?

And, um, isn't that exactly what happens when you move house? Unplug the fridge, move it to the new house, and then plug it back in again?

As far as I know fridges don't need a constant supply of power, I have never seen one powered by a UPS, and none of mine have ever failed to work after being unplugged.

If you unplug, then plug it right back in, it wont be able to start, because the pressure on it is too much. You need to give it about 3 or 5 minutes to let the pressure equalize.

Errr what are P3, P14, etc. good for on the Mach1 LED ? Seems like you can set every temp peaks and such there. There's also a 40°C "P" but that didn't work for me, just changing this. Anyone knows where I can modify startup temp ?

Edit: I mean max startup temp. Hightemp alarm ..

when the compressor is left on its side for a while the oil will slowly move to the lowest point, then when you put it back to normal position you have to wait a while for the oil to drain back to the compressor.
i remember buying an airconditioner and bringing it home in the car laid on its side, then when i started it it didnt cool
left for a few hours and turned it on and it worked this time


as for turning on compressor then off then back on not sure why not to do this, all i know is that it has a warning on my airconditioner when turn off, dont turn on again for 3 mins

The reason for not quick cycling a compressor is the compressor doesn't have enough starting torque when the system is at operating pressures. If you listen you can hear it struggling to start even if you only give it a couple minutes, cycle it even quicker and you will probably trip the breaker. I'm sure this can't be good for the compressor and probably has to potential to cook the compressor.

So play it safe if you powerdown your prom give it a couple minutes to equalize the pressure, or if this is a regular thing just get a seprate power supply for the prom so that it doesn't have to stop running just to reboot your computer.

P26 is the high temp alarm set point.
P14 is the senor calibration offset
P3 is the dead-zone value (for hysterysis) .. no need to touch this

the startup temp is ST1 - P1, so just lower ST1

No I mean the high temperature shutoff is at 40°C. Can I adjust that also ?

I already tried highering this, but then the alarm goes at 38°C (Set it to 45°C)

have you changed anything else (eg P27) ?

scratch that.

if P26 = 40 and P27=2.0 (default) then the alarm will turn OFF when the temp gets below 38 deg C

if P26=45 then the alarm will trigger when the temp exceeds 45 deg

Don't think so. These are my values..

P1 17
P2 15
P3 2
P14 -2.9
P25 -50
P26 45
P27 2
P28 0

from those values the alarm should trigger at 45 deg

:confused:

the problem will go away if you boot up with a lower core voltage/overclock or if you get a second psu

The high side and the low side need time to equalize
themselves. Or someday you're gonna bend the valves
within the compressor on a re-start. These valves are
actually like a "reed."

The oil also need time to make its way back to the bottom
of the compressor.
