1.1 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 5°C - 35°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.

1.2 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 or
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.
1.3 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 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
8
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.
1.4 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.
1.5 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
9
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.
1.6 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.
1.7 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.
