C22: If the buttons are not pressed for a few seconds, the thermostat reverts to displaying  
the room temperature.  
When this parameter is set to 1, the thermostat displays the set-point temperature instead of the  
room temperature.  
C23: This parameter is used to inform the thermostat which function should be implemented  
on output 8.  
Table 6 lists the functions that can be implemented.  
See section “Output 8” for more information.  
CORRECT ROOM TEMPERATURE MEASUREMENT  
To ensure the system measures the room temperature correctly, it is necessary to take the following  
into account.  
-
To ensure the temperature is acquired correctly, the thermostat should be installed where it is not  
exposed to from heat sources, air flows or cold walls (thermal bridges). When using the remote  
temperature probe in conjunction with the thermostat, this applies to the probe rather than the  
thermostat itself.  
-
When using a remote temperature probe, avoid routing the signal wires and power (mains) ca-  
bles via the same conduit as this could compromise the accuracy of the temperature readings.  
If necessary, use bipolar screened cable, connecting the screen to earth on the thermostat only  
(terminal 14). The cable should have a minimum cross section of 1.5 mm2 and not exceed 15 m  
in length.  
-
-
During normal operation with the internal sensor, the thermostat conditions the acquired signal  
by means of a special algorithm that has been designed to compensate for the heat generated  
by its internal components. For this reason, the temperature value displayed when the device is  
switched on may be lower than the real temperature. This effect is entirely normal and disappears  
completely within a few minutes.  
In the thermostat outputs are used to drive large loads (where the current is close to the maximum  
rated value) the heat generated by the internal components may increase. This temperature  
increase may also affect the acquired room temperature value, if measured using the internal  
probe. This problem is not present when using the remote temperature probe.  
If the acquired room temperature reading is considered unsatisfactory for any reason, it may be  
corrected by modifying parameter P12.  
-
-
When the thermostat is connected to a 230 V~power supply, it is essential that the live and  
neutral (L + N) are respected when making the electrical connections.
