Hi Kevin, i think most chillers operate at the one deg difference, if you set them at 26 then they swith on at 27 and off at 26. I know my AM operates the same way.Hi all,
Is there anyone else using a Resun CL650 chiller? I have one and find that the temperature control only seems accurate to aboput 1C.
The issue that I need some advice on is that, with the lack of sensitivity of the chiller thermostat, I am getting a continuos cycle where the chiller (set to 26.5C) kicks in and drops my tanks temp to about 25.5, then my heaters kick in to take the tank temperature back up to 26, which then causes the chiller to kick in again. I have tried widening the gap by setting the chiller to 27 and my heaters to 25 but this does not seem to help much and the temperature still seems to fluctuate between about 25.5 and 26.5. At the moment I am just running fish and soft corals but do want to start SPS once I am happy that the tank has settled. My concern is that this variation may be problematic. Is this a real concern?
