To obtain an estimate of the ambient temperature, the device measures the flow temperature every 5 minutes and performs a moving average across the last 30 minutes. It then performs the following computation:

--uriencoded--\text%7BAmbient Temperature%7D = \frac {%7B\text{Ambienttext%7BAmbient Sensor Raw Value}^{2.2}} {\text{FlowValue%7D%5e%7B2.2%7D%7D %7B\text%7BFlow Sensor Raw Values Moving Average}^{1.2}}Average%7D%5e%7B1.2%7D%7D |
To achieve the instructed room temperature, the device applies the PI algorithm.
