What is a Programmable Room Thermostat?...
An explanation for householders
Put simply a Programmable Room Thermostat
is a timer and thermostat combined in one
unit. With a standard timer you choose your
heating ON times and set your room thermostat (fitted
usually away from the timer) to the desired comfort temperature required. With a Programmable Room Thermostat this
is done within just one unit. i.e. for your heating ON times
you assign a comfort temperature to those times.
The added bonus is that you can also attach a chosen
temperature to the OFF time of your heating. This is called
the set back temperature and is designed to prevent the
temperature in the house falling below a pre-set temperature while the heating is programmed OFF. The advantage
to this function is that by narrowing the gap between OFF
house temperature and ON house temperature (usually
20°c) less energy will be required to bring the house temperature back up to 20°c when the heating is turned back ON.
The recommended set back (OFF) temperature is 16°c,
although it can be set higher or lower depending on personal choice (scale is 7°c-34°c).
Having this function can be of assistance to elderly people as
it prevents the house getting too cold when heating is
programmed OFF.
(N.B!! The unit is capable of operating in an air conditioning/cooling mode also. See instructions for further details.)

Introduction to the ESRTP4
The ESRTP4 is an easy to install and use 7 Day, 5/2 Day or
24 Hr Programmable Room Thermostat which offers four
to six time and temperature changes each day, with
different programmes available for weekdays and for
weekends. It is designed to provide automatic time and
temperature control of heating systems in domestic or
light commercial premises. A large backlit LCD screen and
easy-to-use function buttons ensures simplified programming and operation for all users.
Your ESi Controls Programmable Room Thermostat
includes special features designed to save you energy.
These features are factory set to be OFF to enable the
homeowner to choose whichever features are preferred.
Also, please note these features only apply to your home
heating and not the hot water system.
What is Chronoproportional Control (TPI)?
A chronoproportional (or TPI) room thermostat makes
boilers operate more efficiently and provide close accurate
control. Chronoproportional control is a load compensator as it ensures that 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 just a simple ON/OFF control, like other
domestic room thermostats, room thermostats with TPI
increases boiler efficiency by firing the boiler at regular
intervals, adjusting firing duration with demand, to
2
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.
3
What is Optimum Start?
The Optimum Start adjusts the starting time for home
heating according to the temperature measured within
the building. Instead of setting an arbitrary time for the
heating to come on, the homeowner programmes the
time that the home should be at the desired temperature.
Up to 10% of domestic energy costs can be saved, as the
warm up time is automatically reduced according to the
ambient temperature. Many homeowners set their
heating to start a couple of hours before getting up to
avoid waking up to a cold house. With the Optimum Start
function you don’t need to do this. The actual start time is
automatically delayed or advanced to ensure your home
reaches the set temperature by the programmed time.
What is Optimum Stop?
Optimum Stop saves energy by switching the boiler off a
little earlier than the programmed OFF time. If the house
is up to temperature, you should not notice the effect on
the temperature but you should see a difference in your
energy bill.
What is Landlord Service ?
The optional Landlord Service safety feature offers protection for tenants and landlords against illegal boiler
negligence (in compliance with Gas Safety Regulation 36).
30 days before the boiler is due to be serviced, the LCD
will display SER. If the annual maintenance is not carried
out before the 30 days, the system will only run for a
pre-determined number of minutes per hour before
turning off.
