Placement of the main unit
Select the location of the main unit that is free from direct sunlight. Test the connection to the wireless
sensor before final installation. If there is a problem with the signal reception, select another location. There
is a mounting hole for suspension on the rear of the main unit. Use the part to suspend the main unit You
may also put the main unit on a flat surface.
TIME AND DATE CONTROLED BY THE DCF-77 RADIO SIGNAL
The wireless sensor is equipped with a DCF-77 signal receiver for time and date adjustment, so it is
suitable to place the wireless sensor outdoors for better reception. The DCF-77 is broadcast by a
transmitter from Frankfurt am Main, Germany, with a range of about 1500 km. The time and date is
adjusted every day. In case of poor reception conditions time and date can be adjusted manually.
After time and date have been adjusted manually, they will be readjusted upon reception of the DCF-77
signal.
When the batteries are inserted into the main unit and the wireless sensor and the connection is
established, the wireless sensor will start to receive the DCF-77 signal. If the signal is not received, the
DCF-77 signal reception icon will not be shown on the display. Upon successful reception the reception
icon
will be displayed on the display, if the signal is not received, the icon
will be displayed
The DCF-77 signal is automatically scanned for every day between 10pm and 5pm, when the interference
is at the lowest.
Note: The DCF-77 signal receiver for time and date adjustment is integrated into the wireless sensor,
so the wireless sensor should be positioned to ensure good reception of the DCF-77 signal,
that is outdoors, away from potential sources of interference. Receiving and adjusting time can
take up to 10 minutes.
