The twilight switch WZH-01 is used
to control lighting devices and other
energy receivers depending on luminous
flux density. The system switches on the
lighting at dusk and switches off at dawn.
The switching on threshold can be adju-
sted by the user. The system is resistant
to momentary changes of luminous flux
density and the same guarantees its relia-
bility. The hermetic casing (IP65) secures
the device functioning in unfavorable we-
ather conditions.

The device is designed
for one-phase installa-
tion and must be instal-
led in accordance with
standards valid in a par-
ticular country. The devi-
ce should be connected
according to the details included in this
operating manual. Installation, connection
and control should be carried out by a qua-
liedelectricianstaff,whoactinaccordan-
ce with the service manual and the device
functions. Disassembling of the device is
equal with a loss of guarantee and can
cause electric shock. Before installation
make sure the connection cables are not
under voltage. The cruciform head screw-
driver 3,5 mm should be used to instal
the device. Improper transport, storage,
anduseofthedeviceinuenceitswrong
functioning. It is not advisable to instal the
device in the following cases: if any device
part is missing or the device is damaged or
deformed. In case of improper functioning
of the device contact the producer.

FUNCTIONING
The system works properly after swit-
ching on the power supply from the mains.
Turning the potentiometer in the direction
of “ “ causes the lighting device to switch
on at lower lighting level, in the direction of
“☼“causesthedevicetoswitchonathigher
lighting level. In case the inner sensor’s lumi-
nous flux density falls below the preset thres-
hold the system switches on the output relay
and its lighting devices. The relay is switched
on until the luminous flux density is over the
preset threshold. Using the luminous flux
density hysteresis (delta) and relay switching
off time delay (T) makes the system resistant
to momentary and accidental light pulses.
While mounting the twilight switch pay atten-
tion the switched on lighting does not disturb
the functioning of the twilight lighting sensor.

twilight switches WZx family.
MOUNTING
1. Disconnect the power supply from the ma-
ins by the phase fuse, the circuit-breaker or
the switch-disconnector that are joined to the
proper circuit.
2. Check if there is no voltage on connec-
tion cables by means of a special measu-
re equipment.
3. Fasten the WZH-01 to the base with the
screw.
4. Connect the cables WZH-01 with the her-
metic installation junction box according to
installing diagram.
5. Switch on the power supply from the mains.
6. Take out the rubber hole plug covering the
adjustment of the switch on threshold poten-
tiometer.
7. Adjust the demanded switch on threshold.
8. Put back the rubber hole plug covering the
potentiometer.
Typical application:
The twilight switch operates the light control functions (for example garden
lighting). The device should be installed in a place which is not directly illuminated
by lights that are operated by this twilight switch.
