I'm curious if there are any downsides to keeping glycol temps in higher than normal ranges like 55°F. I am thinking about this for a few reasons but one of them is when I am not fermenting beer there isn't really a need to have the temps down at 28 °F. My concern is if higher temps would assist in nasties growing in the mixture. I have been told glycol itself can help inhibit bacterial growth but I didn't know if anyone regularly kept there chillers at high temps or even just off when not in use. Another reason is I am working on a little fermentation automation and keeping the glycol temps closer to fermentation temp setpoint may help smooth out control and allow for tighter deadland and deviation from setpoint.
Cheers!
