Temperature and Humidity Mode
The weather station supports up to 5 remote thermo-hygro 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 console 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.
Accessing Temperature and Humidity Mode
From the main console unit: Press UP or DOWN until the IN icon
display starts flashing.
Viewing Temperature and Humidity Display for each Channel
For Static Display:
In Temperature and Humidity Mode, each press of CHANNEL rotates display between different

-Temperature and Relative Humidity
-Dew Point Temperature and Relative Humidity
Setting Units for Temperature Display (ºC or ºF)
