INSTALLATION
The Hi-T2 controller can be fixed to the wall according to DIN 503 standard.
On its back, there are some pre-drilled holes which can be removed by exerting the required force with a manual screwdriver, in
order to get fixing holes. Of the 6 slots, use only the outer 2 slots of the horizontal series (see figure).
Before carrying out such operation, open the control panel itself by applying a slight pressure on its lower and upper parts, so as to
separate the rear panel from the front panel.
Use the rear panel and apply the holes in the two slots shown in the figure below.
Do not use the rear panel directly as a template for making holes in the wall, the electronic components may be damaged during
this operation.
