The PWM value for each control module is set by turning the upper rotary
switch clockwise to the PWM section which ranges from 1.0 to 3.5K.
A PWM with the parameter 1.0 is recommended as basic setting. Should the
response behaviour of the heating system be too strong at this setting, i.e.
the rooms are getting too warm, the parameter can be increased to 3.5 step
by step.
Alternatively, two point control (on/off) for the connected actuators can be se-
lected at the control module (see illustration 42). To do so, turn the rotary switch
A to the left and determine a value for the hysteresis (0.2, 0.5 or 0.8K). This way,
excessive switching frequencies around the defined nominal value are avoided.
