I've just started to test the dual temperature controls on a SEC 1000 with my fermentation fridge.
The test involved cooling 23 litres of water in a plastic carboy using an immersibe NTC probe (not the air probe that came with the unit). This optional SS 200mm, 8.5mm diameter probe is from Ibrew & to all intents & purposes is exactly the same as the Mashmaster immersible probe that Mashmaster recommend for use with the SEC 1000, but it is out of stock with them.
Now I fully expected with this volume that their would be a degree of lag in reaching the set temperatures, particularly given the fridge had been off prior to the test. However, I was not expecting the unresponsiveness of the controller: temperature changes towards the set temperature being only 0.1*C every 15 or 20 minutes or so. This rate of change persisted for a number of hours into the test. The fridge compressor didn't seem to have any urgency to reach the set cooling temperature. With the fridge in normal operation mode (ie., without the controller) the compressor starts up with much greater urgency.
In the case of heating the 40 watt globe comes on but after waiting 45 minutes their is no change in the temperature. Given the fridge is only a medium to smaller sized fridge this is a curiosity.
The keypad on the controller is working as it should and all changes in settings that I have made have been properly saved with the power key.
This reaction of the controller does not seem right, particularly in instances when one would want responsive changes during the actual fermentation process.
Feedback from users of this controller who are also using an immersible probe would be welcome or for that matter from any one who has a technical grounding in how this digital controller should be working.
Thanks for your help.
