Default Btw

I finally installed a fan to the relay setup (I wasn't having problems). I don't know if I should post in this thread anymore seeing as my Ace is no longer an Ace since I wired it up. But I want to share with you guys

I don't pretend to understand the finer workings of the unit but whenever I've set the machine to a lower power setting, the element clicks in and out every few seconds. The lower the setting, the longer it takes to click back on. I'd be interested to hear from someone with an electrical background to clarify the issue.
All I know is that if I set the machine to, say 1800w, it cycles on and off and the vigor of the boil reduces until the element kicks in again.

Cheers. Tom

Hi!
I thought the element worked like an electric hob - reducing the setting on the control causes the element to switch off until the temperature range falls below the setting, then it comes on at full power until the range is overshot.

That's how I'm told it works

I do not hear any clicks during boiling, maybe in the newer version that is different? I can hear it on and off when I set a temp like 60C and it is 59.6 it clicks back and when 59.7 it clicks OFF but the element is warm enough to heat water to 60.3C. For boiling it is all the time ON in my case.

Do you have your machine insulated? I've got a couple of foil backed foam mats wrapped around mine to reduce heat loss. Maybe that's the reason for the cycling of the element?

At least in the not-newest controller, each of the two elements are controlled by a relay. So the elements are either on or off. By switching the elements on and off in intervalls the average power over time can be say 1800W. With the large mass of the wort and relatively long time to change temp, I would say this is an okay way to control the power.

No not yet insulated.

Yes with relay it can be on or off but during on there can be different duty cycle like additional PWM controller somewhere in the circuit. For example similar to the one in dimmable lamps. I am not sure though as I didn't open mine yet.
