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 user e.g. if a property only has a simple
mechanical thermostat installed, the energy saving benefits
of a replacement high efficiency condensing boiler will not
be realised as the boiler will rarely be running in condensing
mode. Heating and hot water can account for over 80%
of total household energy usage. Chronoproportional (TPI)
thermostats can provide great cost savings. It 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 10% in both
fuel cost and carbon emissions. This thermostat has the
option of standard setting or TPI.

What is Delayed Start?
Thermostats with the Delayed Start function 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 central
heating is due to come on.
The heating start can be delayed for up to 45 minutes if the
room is already relatively warm, when the weather is milder
for example. This often reduces how long the heating is on
per day, with no comfort loss, saving you energy and money!
The Delayed Start feature can be fully automated and needs
no extra programming.
