...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.

TRT036 7 Day Digital Programmer
TRT036 7 Day Digital Programmer
TRT products are a cost effective comprehensive
range of thermostats and controllers designed
for internal use only.
The TRT036 is a two channel programmer
dedicated to central heating and hot water,
with automatic summer/winter time
changeover (which can be cancelled), 5 day
plus 2 or 7 (individual) day programming,
pumped or gravity fed system, holiday mode,
boost function, advance to next programme
and permanent on/off over ride. There are
three timed control periods per day.
The unit is 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 its
supplied wall plate.
The electrical supply must be isolated before
removing the thermostat from the wall plate.

2. Siting
The TRT036 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.
Always isolate the mains supply before
removing the unit from its wall plate.
The TRT036 is designed to be surface mounted
on the supplied wall plate.
Isolate 230VAC mains supply.
Incoming and outgoing cable should be 1.5mm sq.
Remove wall plate from unit, by undoing
retaining screws, and pivoting the bottom of the
unit outwards. The unit can then be lifted off.
Pass incoming wires through opening in wall plate,
and fix wall plate securely to the wall, using screws
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 to the wall plate.
Connect the conductors to the relevant
terminal, according to the wiring diagram
on the wall plate (or below). Ensure that
the curved brass washer grips the conductor.

need connection to earth. If earth continuity is
required, please use earth terminal on wall plate.
To reinstall the unit on the wall plate hook the top of
the unit over the retaining tabs, and push firmly back.
There will be some resistance from the terminals.
Once in place, secure with the retaining screws.
Restore mains to the unit after checking all system
wiring is complete.
4. Operation
Decide whether weekday/weekend (5-2) or individual
(7) day programming is required, and move the jumper
on the rear of the product (see Fig. 2). Also move the
system jumper to either G (gravity) or P (pumped) as
appropriate for the system.
It is important to make these decisions first, as after
any change of jumper position, reset needs to be
pressed, which will return the unit to default time
and programme.
Reset
When programming a new unit or one that has been
disconnected from the mains for more than
24 hours, open the program access flap and press the
reset button (see Fig. 1a) using a pen or
similar implement which will clear the memory.
All of the screen segments will show briefly, and then
the default programme will be displayed.
Setting time and date
To programme the current time and date,
simultaneously press and hold both the select
and set buttons for 3 seconds.
The option 12 hour or 24 hour is displayed and needs
to be set. Use the up and down buttons

Having done this, heat and hot water programmes for
Tuesday can be started by pressing the set button and
selecting TUES heating using the buttons.
The three on periods for heating and hot water can
be programmed as for Monday.
Complete all 7 days in the same manner. If set is then
pressed twice the TRT036 will return to operating
mode.
This defaults to continuously off – refer to “Setting
the operating mode” to get into timed mode.
Weekday/weekend (5-2) programming on/off times
For 5-2 day mode, time periods will need to be
programmed for M-F (Mon-Fri) and then for S-S (Sat-Sun).
Only 2 sets of times need to be programmed, not 7.
Setting the operating mode
Coming out of programming, the default mode is
‘continuously off’. To enter set operating mode, press
the advance/mode button. One press changes the
output to ‘continuously on’, two presses
‘programmed’, and three presses changes to ‘advance
to next programme’. In advance mode, once the next
time period has past, the programmer returns to
programmed mode.

Omitting days and programmes
Days can be omitted by entering the same time in
each of the 3 on/off programmes for that day.
In 5-2 day mode the weekend can be omitted by using
the same technique for the 2 day (Sat & Sun) programmes.
A programme (usually P2) can also be omitted for a
given day by making the P2 on and off times the same.
This can also be applied to P1 and P3 if required.
Boost
In operating mode, there is a boost facility for
between 1 and 9 hours in one hour steps. Press the
boost button the required number of times for the
number of hours of boost required.
The programmer returns to operating mode 15
seconds after the last button push. To cancel boost,
press the boost button until 0 hrs is shown.
Press and hold the light button and the
programmer will enter holiday mode. Use the
buttons to set the required number of days. The
programmer will return to operating mode 15
seconds after the last button push. To exit holiday
mode, press and hold the light button again.
Screen illumination
Press the light button briefly at anytime,
and the screen will illuminate for 15 seconds.
To clean use a clean dry cloth only. Do not use
any liquid cleaners.
Gravity System
Although the hot water may be programmed to
come on at different times to the heating, by the
nature of the system, it will also come on during all
the on times programmed for heating. This will also
be true when in boost or advanced modes.
