What is a Cylinder Thermostat?...An explanaon for householders
heang when the temperature falls below the thermostat seng, and switching it
off once this set temperature has been reached.
Turning a cylinder thermostat to a higher seng will not make the water heat up
any faster. How quickly the water heats up depends on the design of the heang
system, for example, the size of the boiler and the heat exchanger inside the
cylinder.
The water heang will not work if a me switch or programmer has switched it off.
And the cylinder thermostat will not always switch the boiler off, because the
boiler somemes needs to heat the radiators.
Cylinder thermostats are usually fied between one quarter and one third of the
way up the cylinder. The cylinder thermostat will have a temperature scale marked
on it, and it can be adjusted to the chosen temperature, then le to do its job. The
thermostat must be designed to kill off harmful bacteria in the water. Raising the
temperature of the stored hot water unnecessarily results in wasted energy and
increases the risk of scalding.
A cylinder thermostat switches on and off the heat supply from the
boiler to the hot-water cylinder. It works by sensing the tempera-
ture of the water inside the cylinder, switching on the water

Dual cylinder thermostats combine both the controller and the limit thermostats
into one common unit.
If you have a boiler control thermostat, it should always be set to a higher temper-
ature than that of the cylinder thermostat. In most boilers, a single boiler thermo-
stat controls the temperature of water sent to both the cylinder and radiators,
although in some there are two separate boiler thermostats.

Introducon to the ESCTDE (Electronic Dual Cylinder Thermostat)
The ESi Controls Electronic Dual Cylinder Thermostat* is a revoluonary new
energy saving product, developed exclusively by ESi Controls. It is a direct** and
economical replacement for tradional mechanical dual cylinder thermostats.
With real safety and energy saving benefits and providing accurate temperature
control, it also features a clear and informave LCD display.
The hot water can be stored at any desired temperature between 25oC and 65oC,
with the confidence that the weekly automac one hour “boost” to above 60oC
kills any legionella bacteria, resulng in substanal energy saving.
The LCD display shows the current water temperature and the user defined water
temperature, while the red LED indicates that the unit is calling for heat. The
sensive electronic sensors operate at a far greater accuracy than convenonal oil
filled mechanical dual thermostats, and do not need physical contact unlike
tradional dual thermostats.
The large dial makes it easy to set the required controller temperature (between
25oC and 65oC). While the second (limit) safety thermostat is pre-set to 80oC with
a concealed manual reset, to comply with building regulaons.

Switch
Holiday Switch
This is the black buon located under the display (Fig.1, page 4). Press and hold
the holiday switch for a minimum of 10 seconds unl you hear an audible click, and
this switches the ESCTDE off completely so there is no water heang and no
weekly “boost” heang. When in Holiday mode, the display is off. This feature
should only be used when the property is vacant for extended periods and there is
no requirement for water heang or for the weekly “boost”. Pressing and holding
the holiday switch again (for a minimum of 10 seconds unl you hear an audible
click) will restart the ESCTDE, the display will show the cylinder temperature and
the weekly “boost” will immediately start, and recur every 7 days at the same
me.
