All this means that as soon as you have set your
Thermostat EFIT 550 at your desired comfort temperature,
you do not have to do anything else. Thermostat EFIT 550
will auto matically adjust the heating to meet your
requirements for comfort and economy, no matter how the
weather is changing outside.
This also means that Thermostat EFIT 550 is capable of
detect ing a sudden temperature drop in the room. Instead
of switching the heating on to immediately compensate,
the Thermostat EFIT 550 uses the information stored then
checks to see if this is caused by e.g. the effects of a
window opened for 10 minutes !
Even the programming of economy temperatures (i.e.
during the night) is very simple. You do not have to cal-
culate how much earlier the heating should start in order
to reach a specifi c temperature at a specifi c time. Just
tell the Thermostat EFIT 550 when you want the comfort
temperature and the Thermostat EFIT 550 will take care of
the rest. By learning the rate of heat loss from the room, the
Thermostat EFIT 550 knows when to start heating in order
to achieve the selected temperature at exactly the right
time.
