* Function.
The
ALFA(NET) 29
is a digital hygrostat for panel and wall mounting. The function
from the hygrostat can be programmed for dehumidify or humidify.
The
ALFA
NET
29
has a RS 485 network connection so it can be read out and
adjusted on the Alfanet.
* Installation.
On the topside of the
ALFA(NET) 29
is shown how the sensor, power supply and
relay have to be connected.
After connecting the
ALFA(NET) 29
to the power supply, a self-test function is
started. As this test is finished, the measured relative humidity appears in the
display.
When the relay is activated, the led 'on' will light-up in the display.
* Control.
The
ALFA(NET) 29
hygrostat can be controlled by three push buttons on the front.
These keys are:
SET
- view / change the setpoint.
UP
- increase the setpoint.
DOWN
- decrease the setpoint.
