What is a programmer?
...an explanation for householders
Programmers allow you to set ‘On’ and ‘Off’
time periods. Some models switch the central
heating and domestic hot water on and off at
the same time, while others allow the domestic
hot water and heating to come on and go off
at different times.
Set the ‘On’ and ‘Off’ 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 ‘Off’ heating periods,
or be permanently off.
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 off. 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.

TRT products are a cost effective
comprehensive range of thermostats and
timers designed for internal use only.
The TRT038 is a three channel programmer,
and the TRT039 is a four channel
programmer. Each channel can be
programmed to have three on and off
operations per day. There is automatic
summer/winter time changeover.
The units are fitted with a factory
installed battery which gives up to
24 hours back up of time, date and
programmes in the event of a mains failure.
It is designed to be surface mounted
on the wall plate supplied.
The electrical supply must be isolated
before removing the programmer from
the wall plate.

2. Siting
The TRT038/9 should be located at a position
which eases wiring runs and gives good access
for programming.
It should be mounted approximately 1.5m
above floor level.
3. Installation
This product should be installed by a qualified
installer to current installation standards.
If in any doubt contact the Timeguard Helpline
020 8450 0515.
The TRT038/9 is designed to be surface
mounted on the supplied wall plate.
Always isolate the mains supply before
removing the unit from its wall plate.
Incoming and outgoing wires should be 1.5mm sq.
Remove wall plate from unit, by undoing
retaining screws (see Fig. 2), and pivoting the
bottom of the wall plate outwards. The TRT038/9
can then be lifted off.
Thread the incoming wires through the hole in
the wall plate, and fix wall plate securely to the
wall, using screws (and wall plugs if necessary)
provided. The screws which secure the product
to the wall plate should point downwards.
Allow sufficient excess cable to wire up the unit,
but not too much to make it difficult to close the
unit onto the wall plate.
Connect the conductors to the relevant terminal,
according to the wiring diagrams on the wall
plates or in Fig. 4 below. Ensure that the curved
brass washers grip the conductors.
