2.6 Indoor and Outdoor Temperature and Humidity
The weather station supports up to 5 remote thermo-hygrometer sensors, each sensor corresponding to a separate
channel for the temperature and relative humidity display. The temperature may be shown in degrees Celsius ºC or
degrees Fahrenheit ºF. The trend (rising, steady or falling) of all values is also indicated on the display.
The Main Unit uses the indoor temperature and humidity data to compute a comfort level rating of Wet, Comfort or
Dry.
A temperature alert function is available for each channel. It can be programmed to sound if the channel
temperature exceeds or falls below the pre-configured upper and lower limits.
Note: The temperature alerts have a 0.5 ºC hysteresis to prevent the alerts from sounding constantly due to small
fluctuations near the alert value. This means that after the temperature reaches the alert value, it will have to fall
below the alert value plus the hysteresis to deactivate the alert.
