Offering independent switching times for each week
day the thermostat offers the flexibility required in
buildings with sporadic heating requirements as well
as the more traditional occupancy trends.

Locating the thermostat
The thermostat should be positioned in the area of
the building most critical for comfort. Within this area
the thermostat must be positioned away from heat
sources such as radiators, sun rays and kitchens.
Additionally the thermostat must be located away
from sources of draught such as doors, windows
and ventilation grilles. All of these can lead to false
readings at the thermostat.
