WR-25
Thank you for purchasing a Weather Report. Your package should contain a WR-25 console, wind
sensor, temperature/humidity sensor, rain collector and this manual.
Normal Operation
When in normal operation (no buttons depressed). the instrument displays current wind direction
and speed, cycles current time and date, cycles current indoor, outdoor and if selected, aux
temperatures (if both the indoor and outdoor indicator lights are extinguished, Aux. temperature is
displayed) cycles current barometric pressure, current relative humidity, and cycles daily, monthly
and term cumulative rainfall. By utilizing the hold buttons associated with each display, the user may
select the most important readings to the user. When wind speed exceeds 99 miles per hour, a
small green light will turn on between the digits of the wind speed display.
Trend indicators
(arrows) are located to the right of the temperature, relative humidity, and
barometric pressure displays. If, for example, the current relative humidity was increasing. the up
trend arrow would be lit. If there was no change, no arrow would be lit.
INSTALLATION
We strongly suggest that all the weather station sensors be connected to the weather station
and tested prior to installation so that you may become familiar with the operation of the
instrument.
The WR-25 uses three sensors to gather weather data. The wind direction and speed sensor, the
temperature and humidity sensor (a small black box) and the rain collector (see figure 1). The wind
sensor and the rain collector are designed to mount to a television type mast (not provided). The
cables from the sensors attach to the console via RJ-45 connectors in the rear of the unit. Each
sensor has its own color coded plug, yellow for wind, blue for humidity/temperature and blue for
rain. The blue connectors are interchangeable with each other.
