Linz do you have to disconnect the fridge thermostat ? I thought the sensor was measuring the inside temp and switching the whole fridge on and off , I just looked at it it may be settling at 15 degrees C .
no need to disconnect the internal fridge thermostat - just set it to it's coldest setting. Least that's what I do with my fridge & external thermostat combo. works good now. you're exactly right - it just switches the fridge off & on as required.
Had to stuff around with it a bit initially - the temp on the external thermostat dial didn't seem to match the actual temp in the fridge.
Did a bit of trial & error for a week - Filled a fermenter with water & stuck a digital thermometer from Jaycar in it so I could check the temp from outside without openning the fridge. Then slightly turned the external thermostat dial every few days until I found what setting would keep 12 degrees was & which would keep 18 degrees. now I'm all set
I also sticky taped some string to the roof of the fridge & use it to dangle the thermostat probe from so it's not touching anything, just hanging in the middle of the fridge. and try to get as much of the probe in the fridge as possible.
I blame the metho bottle.
First U move the dial.Then the bottle must come to a new equlibrium with the air temp. This will take longer than a probe in the air, due to the thermal mass of the metho.
Is there an absolute need for the metho? My probe dangles in the fridge and I usually place it on top of the fermentor. This has served me well.
You didn't mention if you had the fridge adjustment set to the lowest setting.
Looks like you're on the right track now.
What's the first beer going to be?
The reason you turn the fridge right down is you want it to adjust quickly, then let the controller do its job.
Giddy up, mate
A vienna Lager , I have never made a lager and looking forwards to it was going to start this Sunday buit may be a bit hot ,I never drink beer while I am brewing lest I forget to add something Pumpy
On the subject of fridge thermostats.... check out this product from RS Components.... with a temp sensor designed to wrap around a pipe (read fermenter) and a range from 6C to 90C.... flexible enough for a HLT also.
Cheap too!!! at well under thirty bucks, must be the best thermostat deal I have seen.
stock number 440-7988 at rs-components.com.au
the site only talks of it being used for heating. May be a problem. ANd there is also a temperature differential of +-3 which is 6 degrees total, pretty big compared to some others. But for the money, is great if it will do for cooling applications.
I need counciling what the #*$@ an I doing wrong with this fermenting fridge, there is gotta be a simpler way do I really neeeed this #*$@ ing
outside thermostatic controller .
I need counciling fast I am suicidal an could drink the neigbours K& K brew or worse still buy a pack of Toohey 's New
Please help I need better advise it cuts in but dont cut off or it dont cut in .
I knows its difficult, but you gotta get the fridge right b4 U put the fermentor in there (with wort). U can put the fermentor in there if U want, with just water, and the temp changes won't be so fast.
Mate, what is the current prob? I'm sure it's not insurmountable.
My job is troubleshooting IT. How much harder can fridge troubleshooting be?
