– For safety reasons, make sure that only equal voltages are switched at the
relay contacts (eg not Rel. 1: 12 V and Rel. 2: 230 V). the device is designed
for appliance class II. Please make sure that to your connected devices without
appliance class II have connected protective conductors according to VDe.
– the relay contacts work as potential-free changeover contacts and must be
wired according to the application. Consumers (e.g. fans) must each be
protected with their own fuse according to their specifi cations.
– Connect a humidity sensor tH-1 to the connector strip (sensor 1/indoor
sensor). Insert the second sensor tH-1 into the connector strip (sensor 2 /
outdoor sensor).
(see chapter „Humidity Sensors Installation“, next page)
– After the assembly of the wiring, fi x all cables in the housing with strain reliefs.
– Replace the lid by snapping it in place and tightening the screw in the area
of the cable entries.

– open the housing cover of the PLs 1000 by opening the screw near the
cable entries and lifting the housing cover.
– In a basement, there may be differences between the air temperature in the
room and the wall temperature of up to 3 °C, the outer walls usually being
colder than the inner walls. In order to keep the heat transfer between the wall
and the humidity sensor tH-1 as low as possible, the indoor sensor should be
mounted at a distance of approx. 1 - 2 cm from the wall. Preferably, it should
be mounted on an outer wall facing north, at least 0.5 m below ground level.
– the outdoor sensor should preferably be mounted on the sun- or rain-protected
north side of the house.
IMPORTANT!
If the sensor is mounted in the area of possible
sunshine (eg south side), avoid direct sunlight by shading the outdoor
sensor as this may lead to incorrect measurements. Mount the sensors in such a
location, that they are protected from the weather to ensure a long service life.
the tH-1 humidity sensors included in the delivery are identical in construction and
can be used as indoor sensor or outdoor sensor. the indoor sensor is connected to the
connector
(Sensor 1
) and the outdoor sensor to the connector
(Sensor 2)
on the connector
strip, see picture of sensor connection tH1 next page.
