c) Delete fan programme
Once you have defined switchpoints (using ‘OK’ or +, Fig.18) and wish to
reverse them, you can use – to access switchpoint deletion, and then use
‘OK’ (Fig.19) to restore the factory setting for the ventilator clearance pro-
gramme menu item.
Reduced room temperature
Because the set room temperature is not always practical as a control
variable, (e.g. for night lowering), under this menu item it is possible to
define a reduced room temperature (Fig. 20).
If the reduction has been selected in the fan clearance program (Fig. 21)
then the system will be regulated to the value that is set here, e.g. to 18°C
room temperature (Fig. 21). It is possible to select a target value between
5°C – 20°C for the reduced room temperature.
