Position
Direct insolation should be avoided, since this will falsify the measurement of
indoor temperature. The sensor for measuring the indoor temperature is fitted in
the area of the keypad. For the same reason, the control should not be fitted
above a heater. Please also make sure that no direct draught from windows or
doors will falsify the measured values.
The central unit may only be installed and operated in dry
indoor rooms. Avoid dew.
Removal of the glass pane
The glass pane is arrested at the keypad of the front panel. It must be made sure
that the matt side is facing the control, and the clear side is facing you.
To detach the glass pane from the control, slide the pane carefully from the
bottom to the top, as you can see in the illustrations.

To open the housing, proceed as shown in
the illustration. The plastic covers for the
mounting bolts of the front panel will be
pressed into the milling holes during final
assembly. Therefore it is very difficult to
remove them, and the covers will be
damaged during disassembly. The
housing therefore contains 3 additional
replacement covers.
To reach the bolts, drill or stab (using a
screwdriver or a pointed object) a hole
into the centre of the plastic cover and
carefully lever them out.
