Seven rooms may be separately temperature 

controlled with Analogue thermostat.

Dew point sensor may be also used on the first 

five control circuits. 

Output 8 indicates the heating/cooling demand 

and the last two outputs control fault-free 

changeover between cooling and heating.  

Output terminal strip points of control circuits out

of use must be left unconnected. 

Thermostat inputs of control circuits out of use 

must be connected in parallel with the 

changeover input of cooling and heating.  

Otherwise output 8 (heating/cooling demand) will 

be continuously switched in cooling mode. 

Control circuit 6 may be used only for heating. 

Comfort/Economy mode: the energy saving mode

may be adjusted on C\E input or via the 

communication line. Then the set point is given 

by thermostat connected to input "THEco", 

and the seven rooms are controlled in parallel 

based on this.

The energy saving mode operates only 

in case of heating; energy saving mode 

set in the cooling mode switches off cooling. 

Mixing valve control: controlled inlet water 

temperature may be set with the use of the 

analogous output (0-10V) as well as of "Temp" 

input. Factory default for cooling is 15 

°

C, and 45

°

C for heating.

If control is not required, the terminal strip points 

of the analogues output and of the measuring 

input must be left unconnected

7.1.1.

Configuration switch

Switch 1 = ON

Switch 2 = ON

Switch 3 = ON

Switch 4 = ON
