To achieve the instructed room temperature, the device applies the PI PID algorithm.

--uriencoded--e = \text%7BSetPoint Temperature%7D - \text%7BAmbient Temperature%7D

--uriencoded--\text%7BValve Percent%7D = \text%7BPrevious Valve Percent%7D + \text{Valve Percent} =  K_p * e(t) + K_I *  \sum_%7B%7D%5e%7B%7D e _{}^{} e(t) + K_d * \Big( e(t)-e(t-1) \Big) + \text{Offset Percent}

See FPORT 0x07 for adjustment of the PI PID coefficients and Offset Percent.

The device considers moving the motor every 5 minutes.
