4. Notes
1. Correct wiring is essential; using instrument to con-
firm L and N before wiring is recommended.
2. Don’t remove too much of the insulation cover from
the wire to avoid short circuit caused by the naked
wire touching the metal 86 size mounting wall box.
3. Don’t let the screw press or touch the wire when
using screw to fix room thermostat in wall box. A
short-circuit risk exists if the wire insulation cover is
damaged by the screw, and if the naked wire con-
nects with the screw.
4. If walls must be painted, mount the room thermostat
after painting, to avoid dust or paint material pen-
etrating the room thermostat and thus damaging
the PCB.
