What Is Delayed Start - ESI ESRTP4RF User And Installation Instructions Manual

domestic room thermostats, room thermostats with TPI
increases 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 reduc-
tions 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.
