partly cloudy to cloudiness).

2.   Weather station predicts possible weather, thus symbols could not agree with current weather. 

Forecast: SUNNY for night means cloudless sky. 

In case of sudden pressure drop weather station would produce storm warning. You can switch 
on/off storm warning function manually. Press ALARM/CHART button in pressure and weather 
forecast mode to switch on/off function of storm warning. After 5 seconds systems returns to 
pressure display mode.

Atmosphere pressure trend

Atmosphere pressure trend indicator (TREND) in shape of arrow in section of weather forecast dis-
plays the changes of atmosphere pressure (going up, constant, going down).

Temperature and humidity mode

Basic block is able receiving data from tree remote sensors, each of them has each own channel 
for temperature and humidity data transmission. Centigrade or Fahrenheit degree can be selected 
as temperature units. Similarly the adequate trend indicator in shape of arrow (TREND) (

going up, 

constant, going down

) is used for pressure trend indication near temperature and humidity data 

acquired from remote sensor.
Room temperature and humidity data are used to estimate the level of comfort indicated by one of 
the tree icons: wet, comfort, dry.  

Basic block is equipped with function of sound warning in case of overrunning the temperature limits 
for each channel. It is possible to program this function thus the basic block issues sound warning in 
case of preset temperature limits overrun.

Notice: Sound warning of temperature limits overrun has hysteresis 0,5

º

С to prevent constant re-

sponse on small fluctuations near preset extreme value. This means the temperature should be in-
creased/decreased up to extreme value plus hysteresis to switch on sound signal.

a)   Temperature humidity mode selection

In order to select this mode press buttons 

«+»/«-» until the icon 

 starts blinking.

b)   Viewing data of temperature and humidity for each channel.

For eternal (cyclic) data display:
In temperature and humidity mode each pressing on button CHANNEL switches data displays 
between different channels. 
For cyclic data display:

For automatic switching between several channels press and hold button CHANNEL until the icon (

) appears. In this case the cyclic channels switching over is going on, at the same time data from 

each preset channel are displayed for 5 seconds.

с)   Temperature units’ selection (

In temperature and humidity mode press and hold button SET to switch between 

º

C or 

º

F units. 

d)   Switching on/off sound warning of temperature limits overrun.
