Installation Instructions
The weather station consists of a display unit, a combined wind and temperature sensor connected by a six-
core cable; a rain sensor (available separately connected by a four-core cable (only three cores used)) and a
separate junction box & power supply.
Sensor wiring
The cables are connected to the individual sensors via the terminal block on the sensor bracket. This can be
accessed by removing the black cover, where a wiring identification label will be found.
Roof Top Wind/Temperature Sensor
This unit should be mounted on a mast of 25-50mm, as high and as far away as possible from chimneys, roof
peaks, buildings, trees and transmitter aerials which may cause wind turbulence or interference. Where
possible the roof top wind sensor should be mounted at least 2 metres above roof peaks and be secured in
position with the arm pointing accurately to the north using the compass provided.
The cable from the roof top wind sensor should be run down to the junction box, making sure it is properly
secured.
Please note!
This cable should not be run in close proximity to power or transmitter cables. If it is necessary
to shorten the cable, please do this when connecting the cable to the display unit.
WARNING:
Under no circumstances should the wind sensor junction box cover, or the terminal block inside
be sealed in any way, as it is designed to breathe.
Optional Rainfall Sensor
- See separate page supplied with sensor.
Junction Box & Power Supply
This unit allows the wiring from the sensors to be terminated away from the main display cabinet and a single
multi-core cable to be wired to the display. Five metres (15 ft) of cable are supplied which may be shortened if
required.
Increasing its length may cause inaccuracies in the temperature read-outs.
To avoid water travelling down cables into the junction box it is
important
to ensure that the cables drop
below the junction box, preferably in the form of a
‘U’ bend. This will allow any water travelling down the
cables to drip off.
The plug-in mains power supply is connected to this unit, so care should be taken to site the junction box near
to a 13A power socket.
Display Console
The Display Console should be wall mounted by the two key-hole slots in the back panel (220mm centres).
The cable may be either channelled into the wall or brought out the side of the cabinet by using the cable
knock-out holes at each side and at the bottom of the cabinet. Please make sure no dust gets into the display
unit
.
The display unit is connected to the junction box by an eight-core cable (only seven cores used) fitted to a
seven way plug. When connecting please
ensure that the connector is the correct way round.
