The hygrostat should be mounted on an inner wall approximately 1.5 m above the floor
and at least 0.5 m from the next wall.
At the location where the unit is mounted, there should be a natural circulation of room
air (no draughts, no corners of the room, not behind curtains, not too close to doors and
windows, and not on an outer wall). Sources of heat and refrigeration (radiators, com-
puters, TV sets, concealed heating pipes, hot or cold water pipes) must be in an ade-
quate distance.
The hygrostat should not be exposed to direct solar radiation.
The unit is supplied with mounting instructions.
