Backup humidistat
Your dehumidifier is equipped with a built-in mechanical humidistat as standard. On request, it can
be equipped with an external wired humidistat, or an external wireless humidistat and thermostat. A
detailed description of the operation of these controllers is described in separate manuals, which are
part of their own packaging.
The mechanical humidistat is a reliable way of measuring and subsequently regulating the humidity
in your pool hall. Its advantage is it’s high reliability as it measures moisture based on the physical
properties of the measuring fiber. In the case of a mechanical humidistat, a hysteresis of 4% and a
maximum of 8% must be taken into account. Hysteresis is a property where the off or on is shifted to
a higher or lower relative humidity value than the actual desired one.
If you use an external (wired or wireless) humidistat, a mechanical humidistat also remains installed
in the device. It functions as a backup in case of failure of the external humidistat. In this case, the
mechanical humidistat is set to 70%. We recommend the user not to change this setting.

Humidity control by remote controller - on demand
An external wireless humidistat and thermostat DRY EASY 300 can be ordered for the pool
dehumidifier as standard equipped with a built-in digital humidistat and ther mechanical
humidistat.
Wireless communication takes place in the 868 MHz band, where the emphasis is on the reliability
and range of the controller. The dehumidifier is controlled primarily by a remote humidistat,
When ordering the DRY EASY 300, there will be no digital humidistat and thermostat
1401F on the cover. The hole in the cover will be covered.

dehumidification, STOP = stop
dehumidification. Values of 20-30-40-
50-60-70 correspond to relative
humidity.

Currently, the humidistat in the

The built-in mechanical humidistat is located in the lower left part of the
device (under the cover of the dehumidifier). The humidistat checks the
humidity level of the sucked-in air and, depending on the set value,
starts or dehumidifies. Ideal humidity of a pool hall is 55-65%. Your
dehumidifier is primarily regulated by a built-in digital humidistat and
thermostat. The role of the mechanical humidistat (black wheel) is to be
a backup controller. Therefore, it is set to 70%. We do not recommend
changing this setting.
The manufacturer recommends setting the required humidity value on the backup
humidistat to the range of 70-80% RH. This will serve as a backup in case the digital
humidistat and thermostat 1401F located on the cover switches off. The recommended
setting of the digital humidistat and thermostat 1401F is in the range of 55 to 65% RH.
