Calibrating Fermenting Fridge Thermostat

[Pumpy]

Seth ,

I turn the dial until I hear the click and the turn it back a bit and leave it an hour it goes to zero the thermostat range is 0C to 38 C .

Can I control it with the internal thermostat ??

 

[Weizguy]

so, does it go to zero at both ends of the dial on the controller?

Seth,Only after the click of the thermostat and then the fridge starts it will go down to Zero .
\otherwise the fridge wont cut in and out on its own ,
The external thremostat is not really controlling the onand off of the fridge it eems like it is doing what the fridge normally does just go down to the coldest point .

Pumpy, I've got one similar but I bought mine. I don't have the technical nouse to build my own. I just stick the probe in the fridge, set the temp and away it goes. Works well. The unit is a Gro-Warm, bought from Grain&Grape.

Pumpy,
It sounds like the switch isn't turning off. at all. Correct?

Going back to basics - is the controller plugged in to the mains power and the fridge plugged into the controller?

Did the fridge work properly before the temp controller was added?
Was the fridge very cold and had to be set to middle calibration to keep things at the right temp?
Or was the fridge a new unit (to your house), and you have no knowledge of settings when used as a straight kitchen fridge?

If you set the fridge internal thermostat to mid range, then see if the controller works. If not, U could reasonably blame the controller.

I'd also try the controller at about 5 degrees below room temp, and see if the switch cuts out. when it reaches the target temp.

See how U go and report back.

Seth,

The controller is plugged into the power - check
Fridge worked Ok before controller added _check
Never noticed the"old' fridge being overly cold but ow I have a thermometer in the fridge always goes to zero .
I have set it on all settings in the internal thermostat and it always goes down to zero .

but I thought the external thermostat was controlling the temp.

It is a two pole switch on the thermostat I just changed the live to the other pole just in case one was for heating and the other was for cooling .

Will report back Thanks Seth for the councilling .

Thanks Seth funny how when you start going to basics how it makes you think more logically about problems Pumpy

 

[Batz]

I look at 3 days for a lager starter

It's easy to get distracted by red herrings when ur in the middle of a problem.
It's usually best to start with "what has happened since it last worked", and start from there.
Glad that I helped to clear your mind, mate.
