As with all ESI’s range of programmers, the ES124716A 16
Amp 1 Channel Time switch, is featured packed, offering
flexibility and reliability making it ideal for use with immersion
heaters and electric boilers.
It has been designed with the homeowner and simplicity in
mind, with an easy-to-use slider to operate the permanent
settings underneath the facia, whilst the temporary settings
are easily accessible and clear with easy-to-use function
buttons, simple overrides and a clear backlit LCD display. The
programmer can be configured for 24 hour, 5/2 day or 7 day
operation with pre-set programs for each mode and the Holiday
mode provides a simple means of adjusting the heating/hot
water quickly.
This programmer can automatically switch your Central
Heating or Hot Water ON and OFF either 2 or 3 times a day,
at whatever times you choose. Timekeeping is maintained
through power interruptions by a replaceable internal battery
(by Qualified Installer / electrician only) designed to last for the
lifetime of the programmer and the clock is automatically put
forward 1 hour at 1:00am on the last Sunday of March and
back 1 hour at 2:00am on the last Sunday of October. The clock
is factory pre-set to UK time and date, but you can alter it if you
want. During installation, the installer selects 24-hour, 5/2 day,
or 7 day programming and either 2 or 3 on/off periods per day,
via the Technical Settings (see installation instructions.
The large, easy to read display makes programming easy and
the unit is designed to eliminate the possibility of accidental
changes to your programme. Buttons normally visible, only
Introduction to the 1 Channel
Programmer

affect your set programme temporarily. All buttons which can
permanently change your programme are located behind the
flip over facia.
Although the ES124716A comes factory set as a standard 1
channel programmer, there also are a number of Installer set
options and if one of these options has been chosen during
installation then the programmer becomes a multifunctional
Power Saver. If the Power saver option is chosen then this may
disable a number features that are set as standard.
Installer Set Programs:
Program 0: Functions as a standard 1 Channel Programmer
Program 1: When the ESI124716A has been set to program
1, the time switch becomes a simple to use Electronic Boost
controller with a single button operation, offering three user-
selectable boost periods of 1 hour, 2 hour or 3 hours and all
other functions have been disabled.
Program 2: If program 2 is selected, then this allows the
user to boost the power as above, but also allows the
installer to set On and Off times. Once the On/Offs have
been set, all other functions apart for the standard 1, 2 or 3
hour boost, all other functions are disabled.
