tempFormat Temperature format F for Fahrenheit, C for Celius. The algorithm always uses fixed point Celcius format internally, but it converts all settings that go in or out to the right format. tempSetMin Minimum temperature setting The fridge and beer temperatures cannot go below this value. tempSetMax Maximum temperature setting The fridge and beer temperatures cannot go above this value. Kp Kp parameters of PID The beer temperature error is multiplied by Kp to give the proportional part of the PID value. Ki Ki parameters of PID When the integral is active, the error is added to the integral every 30 seconds. The result is multiplied by Ki to give the integral part. Kd Kd parameters of PID The derivative of the beer temperature is multiplied by Kd to give the derivative part of the PID value. pidMax PID Maximum You can define the maximum difference between the beer temp setting and fridge temp setting here. The fridge setting will be clipped to this range. iMaxErr Integrator: maximum temp error °C The integral is only active when the temperature is close to the target temperature. This is the maximum error for which the integral is active. idleRangeH Temperature idle range top When the fridge temperature is within this range, it won't heat or cool, regardless of other settings. idleRangeL Temperature idle range bottom When the fridge temperature is within this range, it won't heat or cool, regardless of other settings. heatTargetH Heating target upper bound When the overshoot lands under this value, the peak is within target range and the estimator is not adjusted. heatTargetL Heating target lower bound When the overshoot lands above this value, the peak is within target range and the estimator is not adjusted. coolTargetH Cooling target upper bound When the overshoot lands under this value, the peak is within target range and the estimator is not adjusted. coolTargetL Cooling target lower bound When the overshoot lands above this value, the peak is within target range and the estimator is not adjusted. maxHeatTimeForEst Maximum time in seconds for heating overshoot estimator The time the fridge has been heating is used to estimate overshoot. This is the maximum time that is taken into account. maxCoolTimeForEst Maximum time in seconds for cooling overshoot estimator The time the fridge has been cooling is used to estimate overshoot. This is the maximum time that is taken into account. fridgeFastFilt Fridge fast filter delay time The fridge fast filter is used for on-off control, display and logging. It needs to have a small delay. 0 = 9 Seconds, 1 = 18 Seconds, 2 = 39 Seconds, 3 = 78 Seconds, 4 = 159 Seconds, 5 = 318 Seconds, 6 = 639 Seconds fridgeSlowFilt Fridge slow filter delay time The fridge slow filter is used for peak detection to adjust the overshoot estimators. More smoothing is needed to prevent small fluctuations to be recognized as peaks. 0 = 9 Seconds, 1 = 18 Seconds, 2 = 39 Seconds, 3 = 78 Seconds, 4 = 159 Seconds, 5 = 318 Seconds, 6 = 639 Seconds fridgeSlopeFilt Fridge slope filter delay time The fridge slope filter is not used in the current version. 0 = 27 Seconds, 1 = 54 Seconds, 2 = 2 Minutes, 3 = 4 Minutes, 4 = 8 Minutes, 5 = 16 Minutes, 6 = 32 Minutes. beerFastFilt Beer fast filter delay time The beer fast filter is used for display and data logging. More filtering give a smoother line, but also more delay. 0 = 9 Seconds, 1 = 18 Seconds, 2 = 39 Seconds, 3 = 78 Seconds, 4 = 159 Seconds, 5 = 318 Seconds, 6 = 639 Seconds beerSlowFilt Beer slow filter delay time The beer slow filter is used for the control algorithm. The fridge temperature setting is calculated from this filter. Because a small difference in beer temperature causes a large adjustment in the fridge temperature, more smoothing is needed. 0 = 9 Seconds, 1 = 18 Seconds, 2 = 39 Seconds, 3 = 78 Seconds, 4 = 159 Seconds, 5 = 318 Seconds, 6 = 639 Seconds beerSlopeFilt Beer slope filter delay time The slope is calculated every 30 seconds and fed to this filter. More filtering means a smoother fridge setting. 0 = 27 Seconds, 1 = 54 Seconds, 2 = 2 Minutes, 3 = 4 Minutes, 4 = 8 Minutes, 5 = 16 Minutes, 6 = 23 Minutes lah Use light as heater If this option is set to 'Yes'the light wil be used as a heater. 0 = No, 1 = Yes hs Rotary encoder trigger step When you feel like you have to turn your rotary encoder two steps for every trigger, set this to half step. 0 = Full step, 1 = Half step heatEst Heating overshoot estimator This is a self learning estimator for the overshoot when turning the heater off. It is adjusted automatically, but you can set adjust it manually here. This does not stop further automatic adjustment. coolEst Cooling overshoot estimator This is a self learning estimator for the overshoot when turning the cooler off. It is adjusted automatically, but you can set adjust it manually here. This does not stop further automatic adjustment. minCoolTime Minimum cooling time *1 minCoolIdleTime Minimum idle time before cooling *1 minHeatTime Minimum heating time *1 minHeatIdleTime Minimum idle time before heating *1 deadTime Minimum idle time between switch of heating and cooling. *1
