THERMOPROGRAM TH450
The TH450 programmable thermostat has been
designed to ensure perfect temperatures any time of
day, any day of the week.
It features a new temperature control system and
new functions.
The TH450 has been designed to adapt itself to all
types of systems featuring different thermal inertias
(convector heaters, radiant underfloor heating, elec-
tric heaters, etc.), it ensures maximum comfort and
savings in any environmental condition.
It is possible to choose between differential control
mode and integral proportional mode (cycles per
hour management). The latter allows the program-
mable thermostat to reduce the time the boiler is in
operation as the room temperature approaches the
desired temperature.
