The remote search icon will turn on： Do not touch any buttons until the remote sensor reports in, otherwise the remote sensor search mode will be terminated and the search icon will turn off. When the remote sensor data has been received, the console will automatically switch to the normal mode, and all further settings can be performed.

  • Page 16: Sensor Operation Verification

    If the signal reception is not successful (normally during the day due to solar interference), the sensor search will be cancelled, the outdoor temperature and humidity will update as normal, and the RCC search will automatically resume every two hours until the signal is successfully captured.

  • Page 17: Sensor Placement

    3.6 Sensor Placement It is recommended you mount the remote sensor outside on a north facing wall, in a shaded area, at a height at or above the receiver. If a north facing wall is not possible, choose a shaded area, under an eve. Direct sunlight and radiant heat sources will result in inaccurate temperature readings.

    4.2.2 Relative Pressure Calibration You will want to calculate your barometric pressure to an official reporting station in your area. Since barometric pressure does not drastically change in a 50 mile radius (unless the weather is rapidly changing), this method of calibration is acceptable.

    The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level pressure around the world. Relative pressure measurements greater than 29.92 inHg (1013 mb) are considered high pressure and relative pressure measurements less than 29.92 inHg are considered low pressure.

    The reason the current conditions do not match the forecast icon is because the forecast is a prediction 24-48 hours in advance. In most locations, this prediction is only 70% accurate and it is a good idea to consult the National Weather Service for more accurate weather forecasts.
