Installation Instructions
Installation
 Remove wallplate from unit by unscrewing the two screws
on the bottom edge of the unit.
From the top left hand corner of the wallplate, there must
be clearances of at least 140 mm to the right, 15mm to the
left, 30mm above and 100mm below in order to mount
the plug-on module.

4
The wallplate must be securely mounted either directly to
the wall using suitable wood screws or to a ush mounted
1-gang electrical accessory box using M3.5 screws.
Cable access can either be from behind for concealed
cabling, or from below for surface cabling. If surface cable
is used, cut out cable access slot on plug-on module prior
to mounting the module.
For wiring connections refer to diagram on page 5.
TS715-Si models are double insulated and do not require
an earth connection, however a parking terminal is
provided on the wallplate. This is clearly marked with an
Earth symbol.
Prior to mounting the plug-on module, DIL switches on
the rear of the plug-on module must be set. See diagram
on page 5 for available options.
Mount plug-on module to wallplate by locating tabs on
top of wallplate in apertures on rear of module, hinge
down and press rmly to wallplate before tightening
securing screws on bottom of wallplate.

Copy Functions Explained
There are 3 possible copy functions available. These are;
Standard Copy, Enhanced Copy, and AB copy. Copy functions
are enabled/disabled in the Advanced Programming Options
(page 5).
Standard Copy: Pressing copy will copy the previous days
events into the displayed day. The unit will then display the 1st
event for the new day. This copy function is present only if the
unit is set to run in 5+2 or 7 day mode.
Enhanced Copy: The enhanced copy function is available in 7
day mode only. This allows any day to be copied to any other
day, or days. To use the enhanced copy function go into the
event programming using the PROG button, then:
Use the DAY button to nd the day to be copied from.
Press the COPY button to select the day to be copied from.
When selected, the day should begin to ash.
Use the DAY button to nd the day to be copied to.
Press COPY button to copy the selected day.
Repeat steps 3 and 4 to select and copy other days.
To stop copying, use the DAY button to go back to the
ashing day and press the COPY button. The previously
ashing day will stop ashing to indicate it has been de-
selected.
NOTE: When a day has been copied to, it will remain visible and
not ashing when the DAY button is used to select other days.
AB Copy: The AB copy function is available in 5+2 mode only
and only if activated in the Advanced Programming setting.
A and B days, when selected, can be any group of days e.g. 5+2,
4+3 etc. The days do not have to run in sequence. For example,
to operate in a 5+2 day mode the days can be set as follows:
1.

Service Interval Timer
The TS715 Si is tted with an installer setback service interval
timer. If this feature is required please contact our technical
department. Setting instructions for this gas safety feature are
only available to bona de heating installers.
To use the AB copy function – press the PROG button:
This will show the“A”days, with all the days selected.
Use the DAY button to highlight a day.
Subsequent presses of the DAY button will increment
through the days.
Press the +button to select a specic day as an “A” day, or
press the –button to specify a day as a“B” day.
Once the day has been selected as an “A” or “B” day the
programme will automatically jump to the next day.
When the last day of the week is active, pressing +, -, or DAY
will move back to the “A” days displayed with no selected
(ashing) days (see image below).
Repeat 2 to 6 until all selections have been made.
When selections are completed, press the PROG button to
move to event programming.
Event Programming in AB mode

What is a programmer?
What is a programmer?
... an explanation for householders.
Programmers allow you to set ‘On’ and ‘O’ time periods.
Some models switch the central heating and domestic hot
water on and o at the same time, while others allow the
domestic hot water and heating to come on and go o at
dierent times.
Set the ‘On’ and ‘O’ time periods to suit your own lifestyle.
On some programmers you must also set whether you want
the heating and hot water to run continuously, run under the
chosen ‘On’ and ‘O’ heating periods, or be permanently o.
The time on the programmer must be correct. Some types
have to be adjusted in spring and autumn at the changes
between Greenwich Mean Time and British Summer Time.
You may be able to temporarily adjust the heating
programme, for example,‘Override’,‘Advance’or‘Boost’. These
are explained in the manufacturer’s instructions.
The heating will not work if the room thermostat has switched
the heating o. And, if you have a hot-water cylinder, the
water heating will not work if the cylinder thermostat detects
that the hot water has reached the correct temperature.
The text below has been edited and approved
by the Plain English Campaign, who has issued a Crystal
Mark to be displayed with it.
Please note: A timeswitch is a single channel programmer. It will
allow you to set your system’s On and O periods.
