Heating type

Cooling type

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.
