ambient environment for the user e.g. if a property only has

a simple mechanical thermostat installed, then 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?

The ESi Delayed Start function offers real energy savings. Save

as much as 10% on your heating costs. 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 an hour 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.

To set the temperature, turn the dial until the desired

temperature is shown in the LCD display. The LCD display will

flash the desired temperature for (approximately) 5 seconds

before returning to display the current room temperature.
