compensator as it ensures the boiler ON time is
reduced to a minimum and matches the boiler
heat output with the heat loss. This reduces
the net temperature of the return water to the
boiler. This is due to the TPI (Time Proportional
and Integral) advanced energy saving feature.
Rather than a simple ON/OFF control, like
other domestic room thermostats, room
thermostats with TPI increase boiler efficiency
by firing the boiler at regular intervals,
adjusting firing duration with demand, to
maintain SET room temperatures. This gives
them a great advantage over other domestic
room thermostats and achieves a constant
ambient environment for the end user.
TPI room thermostats can be used on any
boiler, with underfloor and radiator systems,
zoned heating and electric heating systems.
The use of an electronic thermostat with
chronoproportional capability provides closer
temperature control plus possible reductions of
up to 10% in both fuel cost and carbon
emissions.
Delayed Start
Thermostats with Delayed Start software have
been shown to reduce heating costs by as
much as 10%. This feature delays the start-up
of the heating, depending on how warm the
room temperature is at the time when the
heating is due on.
The heating start can be delayed by up to 45
minutes if the room is already relatively warm.
This often reduces how long the heating is on
per day, with no comfort loss, saving energy
and money. The Delayed Start feature can be
fully automatic and needs no extra
programming.
Optimum Start
Optimum Start adjusts the start time for your
heating according to the temperature
measured within the building. Instead of
