Installation of operating unit
The operating unit is battery-powered and communicates with the weather
station per radio.
When you select the assembly site, please avoid direct sun because this would
distort the measurements of the indoor temperature. The appropriate sensor is
integrated in the lower part of the operating unit. For the same reason, the
operating unit should not be installed above the heater. Please make also sure
that there is no direct air supply coming from windows or doors which would
distort measured values.
The operating unit may be installed and operated in dry
interior rooms only. Relative air humidity may not exceed 80%.
Avoid condensation.
Notes on radio installations
Please make sure when planning that there is appropriate radio reception. The
operating range of radio control systems is limited by the legal regulations for
radio installations and by structural conditions (if the radio signal must permeate
through walls and ceilings).
In order not to affect the quality of reception, a minimum distance of 30 cm
between the radio transmitters should be adhered to. Both operating unit and
weather station should therefore be assembled in adequate distance to other
radio transmitters. Strong local radio installations (e.g. radio headsets) which
transmit with equal frequency (868.2 MHz) may interfere with reception.
Furthermore, the operating unit should not be installed in the direct vicinity of
metallic surfaces.
Commissioning
If a device is brought from a cold to a warm area, condensation
can form. Before starting the device up, please ensure there is
no moisture inside it (if necessary leave to dry).
After the system has been wired and the connections have been checked, please
proceed as follows:
•
Switch on the power supply voltage of the weather station.
