The hysteresis change mode is signaled by a flashing HI. Turn the knob to the left or

Changes in the delay
The delay prevents too frequent activation of the actuator, e.g. due to temporary drafts
(caused by opening the window, etc.).
The delay change mode is signaled by
a flashing 90:SE. By turning the knob
left or right, we set the delay.
90:SE – delay of 90 s (preset),
0:SE – no delay
