4. Siting

• The TRT038N 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.

5. Installation

5.1 Ensure the mains supply is switched off and the circuit supply fuses

are removed or the circuit breaker turned off.

5.2 Remove the wall plate from the unit, by undoing the retaining screws,

and pivoting the bottom of the unit outwards. The TRT038N body can
then be lifted off.

5.3 Mark the position of the mounting holes on the wall using the wall plate

as a template. Drill out the mounting holes taking care to avoid any
joists, electrical cables or water/gas pipes that may be hidden beneath
the surface. Insert the rawl plugs into the holes.

5.4 Pass the 230V 50Hz mains supply and load cables through the opening

of the wall plate. 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.

5.5 Fix the wall plate to the wall using the correct mounting screws for the

3

rawl plugs installed. The retaining screws which secure the unit to the
wall plate should be at the bottom.

5.6 Terminate the cables into the terminal block ensuring correct polarity

is observed and that all bare conductors are sleeved (See section 6.
Connection Diagram). Make sure that the curved washer grips
the conductor.

5.7 To reinstall the unit onto the wall plate, first ensure the wall plate

retaining screws are loosened enough to clear the TRT038N body, then
engage the top of the TRT038N onto the wall plate retaining tabs, and
push firmly downwards and then upwards. There will be some resistance
from the terminals.

5.8 Once in place, secure with the retaining screws making sure not to

over tighten.

Programme Modes

Copy Function

Note that the images used for the COPY function are for guidance only
and may not represent the users situation directly.

11.1 Copy mode can only be used directly after programming at least one day.
Press the copy button to copy the day that has just been programmed.

12

11.2 Press copy, and the programme from the original day copied will be
applied to the next subsequent day. The programmes used from the
original day copied will be displayed on screen for the following day.

11.3 The next subsequent day will be displayed; again the copy button can be

used the advance buttons marked beside the + or – indicators to select
an alternative day of the week and then press copy to apply the settings
from the day originally copied.

and Sat-Sun as a set) enter programmes for Monday and copy the

13

programmes until Friday. When Saturday is displayed on screen press
enter to set the alternative weekend times and then press copy
to apply those times to Sunday.

Boost Function

11.5 Pressing the boost button from the OFF position will give a 1 hour boost.

third time will cancel the boost operation.

11.6 Pressing the boost button from the ON position adds a 1 hour boost. A
second press will add a 2 hour boost to the next off time. Pressing the
boost button a third time will cancel the boost operation.

11.7 The boost option can be set independently for all channels using the
separate boost buttons. During any boost period the boost button will
remain illuminated.

Advance

11.8 Pressing the advance button, changes the output status until the next

14

programmed change, e.g. if a programme is due to switch ON at
17:00 and OFF at 22:00 the advance button can be pressed to switch
ON the output ahead of time. Therefore the programme would run
from when the advance button is pressed until the next programmed
off time (22:00).

11.9 The advance button can also be used for the opposite, e.g. if a
programme is due to switch OFF at 22:00, pressing the advance button
would switch OFF the programme ahead of time. This would result
in the unit displaying the next programme ON time which in this case
would be 06:00.

Over-Ride

11.10 Over-Ride includes 4 different functions, all day, ON, OFF and AUTO.

Each function can be selected by pressing the over-ride button
assigned to the channel you require to override.

until the third programme OFF time scheduled for that day has been
reached for the selected channel.

11.12 If set to ON, the output will be switched ON permanently

15

for that channel.

11.13 If set to OFF, the output will be switched OFF permanently

for that channel.

11.14 If set to AUTO, programmed periods will run as normal as they have

been set to for the current day.
