The dehumidifier can be equipped with a remote humidistat on request. In this case, the
dehumidifier has two humidity controllers. One of them is a built-in mechanical humidistat inside the
pool dehumidifier, the other is an external wired humidistat. The dehumidifier is controlled primarily
by the remote humidistat, provided that the built-in humidity controller inside the dehumidifier is set
to a higher desired humidity value than the remote humidistat.
If your dehumidifier is equipped with a hot water insert and/or a solenoid valve also, you must use a
humidistat with an EBERLE HYG7001 thermostat to activate the dehumidifier’s air heating function,
or you must have an external thermostat connected.
4.5 Fan regulation
Under the inner cover of the device there is a two-position fan mode switch. In the first position,
the fan runs even if the compressor of the device does not, it is a so-called CONTINUOUS mode . In
the second position, the fan runs simultaneously with the compressor, it is a PERIODICAL mode .
The continuous operation mode of the fan is more optimal, as the humidity sensor built into the
device continuously senses the humidity, which achieves higher accuracy. At the same time, the
continuous operation of the fan mixes the air in the room better. The fan control is set by the
installation company according to the user's requirements. DRY300-400 models are equipped with
only one fan speed and, in the case of continuous operation, the fan is still running at full speed.
DRY500 is equipped with two speeds. In the case of continuous operation while the compressor is
switched off, the fan runs at low speed, which effectively mixes the air in the pool hall.
4.6 Compressor control
The start of the compressor is delayed by 3 minutes due to it‘s protection. Depending on the
humidity and ambient temperature, this may take longer. If the compressor stops, it will start
automatically after 3 minutes at the earliest. The user must not manipulate the setting element of
this time protection. The task of time protection is to equalize the pressures of the refrigerant in the
dehumidifier‘s system.
After a long period of inactivity, it is normal for the compressor to try to start 4-6 times
before finally turning on. It also depends on the current air temperature. A lower ambient
temperature (approx. 22°C) requires more attempts, a higher temperature (approx. 30°C)
usually requires only 1 attempt.
CONTINUOUS DUTY OF THE FAN
PERIODICAL DUTY OF THE FAN
When ordering EBERLE HYG6001/7001, there will be no digital humidistat and
thermostat 1401F on the covers and the hole in the cover will be covered with a cover.
