Parameters heating / cooling type allow for adapting the controller to
the type of heating / cooling. In addition, the controller features two
control algorithms: one for continuous mode (0..100%) and one for
PWM mode (On/Off). The mode is selected via parameter "Control
value type". The control value type is identical for all operating modes.
In continuous mode, the associated PWM output is "On" at
continuous control value ≠ 0.
In PWM mode, cycle time and pulse width are adapted to the type of
heating / cooling, the setpoint, and the measured room temperature.
The min. cycle time is 12 minutes, the min. pulse width is 4 minutes.
The continuous control value issues 0% or 100% in this operating
mode.
