Turn the PTK until the desired interval is reached (up to
250 seconds).
For small spaces we recommend to select a short
interval (5-10 seconds), and for large spaces a
somewhat longer interval. If the temperature keeps
fluctuating with the current settings, you can change
the interval. If the temperature often increases too high,
it is recommended to shorten the interval. If the
temperature often falls too low, it is recommended to
increase the interval.
Confirm by pressing the PTK.
You return to the boot menu.

In the "Auto" mode the fan will automatically run
faster if a measured value is too high. That is, if:
TMP is higher than TMP setpoint + hysteresis;
•
RH is higher than RH setpoint + hysteresis;
•
the lights are off and CO
•
setpoint + hysteresis.
In such a situation, the fan will slowly accelerate.
Between two accelerations the fan will wait the number
of seconds that you set during startup in the next
screen (box delay):
