The control is designed for wall mounting according to DIN 503. Indoor use.
On the back of the control, there are pre-drilled slots to be removed by applying pressure with a screwdriver, so that the holes for fastening can
be drilled.
Before doing so, open the control itself, applying light pressure to the bottom and top of the control, so as to separate the back panel from the
front panel.
Use the back panel and drill the holes in the two slots.
Do not use the panel directly as a template to drill holes in the wall, the electronics could be damaged during this operation.
