Occasional control (faster increase in humidity)
With a rapid increase in humidity (causes e.g. by showering, bathing) the fan turns
on as early as possible before reaching the set threshold, to eliminate effectively
excessive humidity and restore the comfort zone in the room.
When reaching the turn off threshold, the fan shuts down according to the timer
setting. The switch-off threshold is fixed at 10% below the threshold.
5. Runtime lmit
In cases with lasting
moisture accumulation (when the relative humidity of the
inflowing air is already above the set point, or permanently damp laundry is in the
room, or poor air exchange due to a small-sized room or clogged air vent opening)
the fan will shut down automatically after 2 hours. During stop time any humidity
measurement will be ignored. The required ventilation continues to be activated,
enabling ventilation on demand, until the stop time function is terminated.
There are two possible stopping times:
Short stopping time:
The humidity has dropped down after two hours under the adjusted switch on
threshold, but hasn’t yet reached switching off threshold. The fan is switched off; it
runs a short stop time of one hour.
Background
:
There is humidity decrease (reduction) during the fan operation. The
reduction however hasn’t been enough to fall below the turn off threshold. Short stop
time activated since it can be assumed that after a short break the humidity can still
be effectively reduced.
Long stopping time:
The humidity hasn’t dropped down after two hours under the adjusted switch on
threshold. The fan is switched off; it runs a long stop time of six hours.
Background
:
Since the humidity value hasn’t fallen below the set switch on it can be
assumed that another venting makes no sense.
If no stop times required please enable hygrostat function.
6. Hygrostat function
DIP switch 5 controls the hygrostat function. The control switches are as a “smart”
hygrostat. The humidity operation is identical, but without shutdown by the run time
limit, if the switch off threshold is not exceeded.
7. Timer function activation
Via DIP switches 7 and 8 the time function (delay, overrun timer) can be activated or
deactivated at the desired stage.
8. Switch ON delay
The switch on delay can be set via DIP switches 1 and 2. Then the fan will turn on
after the set delay time (0, 45, 90, 120 sec.). The delay is only performed at standstill
of the fan. When switching between on-going stages applicable switch ON delay will
be ignored. By simultaneous activation of both stages, switch ON delay is also not
taken into account.
