Introduction:
The ETU17 is a compact seven day timeswitch which has six programmes,
each of which can be dedicated to 7 day, 5 day, 2 day or individual day
operation. It has a random switching capability useful for security applications.
It is also able to switch up to 500W of low energy (compact fluorescent) lamps
or linear fluorescent tubes which is particularly useful as this type of energy
efficient lighting is often used for security applications. The ETU17 is also well
suited to control washing machines, tumble driers, dish washers and other
appliances up to 13A (3kW).

Battery:
This product has a factory fitted rechargeable battery. If the ETU17
is left out of a live socket for more than 1 month the display may go
blank. In this case plug into a live socket, wait four hours, and apply
reset – see section 1 before programming
.
Programming Overview:
This is a seven day (weekly) timeswitch which has six programmes,
each of which can be block programmed to work on all of the five
weekdays, both weekend days, or all 7 days (24 hour operation).
Programmes can also be designated to operate on individual days.
Only two setting buttons are required, <Change> and <Program>.
In normal operating mode the <Change> button is used to switch
2 3
ON or OFF, overriding the timeswitch until the next programmed OFF
or ON time. During programming the <Change> button is used to
set the hours, minutes and days. The <Program> button is used to
select the clock time and day or the 6 programmed ON/OFF times
and days and to review them once they have been set. Each time the
<Program> button is pressed in programme mode the display will
flash either the days, hours or minutes in turn, starting with the clock
time and day then the first ON time and day(s), first OFF time, second
ON time and day(s) etc. Wherever the days, hours or minutes are
flashing they may be set using the <Change> button. Once set the
<Program> button is pressed again to proceed to the next stage.

Normal Operating Mode:
In normal operation the ETU17 will display
the correct day and its time with the colon
flashing. The output status will be shown by
either ON or OFF on the display.
1. To Reset Before Programming:
(To alter c lock time or modify programmes – see section 5)
To clear programmes from memory and reset the ETU17 press the
<Change> and <Program> buttons together until the display goes
blank (approximately 3 seconds).
Release the buttons and the display will fill
with its complete range of characters and
3 4
then clear to show clock and day 1 symbol
flashing. This procedure is essential with a
new ETU17 and is recommended if major
reprogramming is required subsequently.
You are now in the clock setting mode at the beginning
of the programme sequence.
