Temperature controller + Countdown timer

Recommended Posts

I have been using a Keg King temperature controller which does a top job in keeping my freezer within a 18º to 20º range for my second fermenting.

But i am finding that the heating element does too good a job and reaches the "Set" limit very quickly, and the created heat is enough to trigger the cooling soon after that, and cycles thru this approx every hour. basically a heat versus cool battle. In the warmer nights +22º, i just disconnect the heating and it is not a problem.

Does anyone know if you can set the controller to turn the heating off at a lower temp other than the "Set" temp?  

I thought of using a 240V timer that has a countdown function, to achieve the same result.

I hope that all makes sense, any thoughts would be appreciated.

I have the same temp controller, it works a treat.

You can play with the settings and change the delay time of the cooling, or heating. in your case it sounds like you could play with the delay of the cooling. Check out this video here: https://youtu.be/5ha5gsI8Gb4

At about the 8 minute mark he explains how to change the settings for a fermentation chamber

Thanks Smooth Hoperator

I have watch that video before, but did not pick up on the bit about the delay setting.

I must have a newer version as my E5 E6  t1 settings are different to the video, which did not help, but once i realized that it made more sense. 

I have set the delay time (t1) between heat & cool to the max 30mins, which should improve the situation in the cooler nights.

the countdown time needs to be set manually after each cycle

That seems like a massive hassle. 

The delay definitely does sound like the best option ?
