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.

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.

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.
