Fermentation Temperature control with fridge and fermwrap
Posted: Mon Apr 07, 2014 9:55 am
Hi all my name is Trevor and I'm new to this forum. I'm sorry if I am asking a question that has been asked before but I can not find the answer. If this has already been discussed could someone send me the link please?
I have the BSC 460. I ferment in a mini fridge and have a fermwrap that I attach around the fermenter for heating.
I have made a box with an outlet with two SSR each one controls one of the outlets. One for fridge (cooling) and one for heating (fermwrap)
I have a thermowell that the temperature probe goes into during fermentation.
This is my first run on using this set up and I am having trouble with temperature reading. The temperature is reading approx. 10 degrees higher than it really is. It was reading the temperature accurately when it was set up in the fridge before fermentation. Now that fridge and fermwrap are plugged in the temperature has been off by 10 degrees. Is this a magnetic field issue? I have read about this and have grounded my bcs which did help with another temperature probe that was running 50 feet. This one however is not running a long distance and the probe and wire are wired directly to the BCS without any extension wire.
My second question is if anyone has a good way of programing this BCS for heating and cooling with a fridge and a heating element. I have tried with hysteresis control but I am worried about over cycling my fridges compressor. I know some controllers out there have a way to program a delay from 1 to 10 min so temperature swings do not over cycle the compressor. Any ideas would be most appreciated.
Thanks in advanced for any help.
