TP5E

Electronic Programmable Room Thermostat

USER INSTRUCTIONS

INITIAL START-UP
Slide the battery cover to the left to

reveal the programming buttons
(PROG, +, -). Slide the cover further
left to reveal the battery compartment.
Fit the batteries (supplied) making sure
the + ends align with the ⊕ symbols at the back of the
compartment. RESET the TP5E as described below.
The blank display changes to that shown in fig. 1. (If the
actual air temperature in the proximity of the unit is higher
than 20°C the flame symbol will not be displayed). Slide
the battery cover to the right but leave the buttons visible.

RESET

The TP5E may be reset to the factory pre-set programme,
12:00 on day 1, and 20°C by pressing and holding down
the four buttons, temperature s and t , time + and -, until
the display becomes blank. This may be necessary after
a severe electrical storm or serious fluctuations in the
electricity supply, indicated by a malfunction or spurious
information such as 18:88 on the display.

SETTING THE CLOCK

Press the PROG button once; the colon
stops blinking, (see fig. 2). Use the +
and - buttons to set the time. Pressing
and releasing these buttons changes
the time by one minute, holding these
buttons down changes the time quickly.
When the time is correct press the
PROG button to start the clock; now
only the colon and day number are
displayed, (see fig. 3). Use the + and ­buttons to select the correct day
number. (It is intended that day 1 is
Monday, therefore days 6 and 7 are
Saturday and Sunday - the weekend).
Press PROG to display the first setting,
(see fig. 4).

REVIEWING THE EXISTING
SETTINGS

Now each press of the PROG button
shows, in sequence, the twelve set
times and their associated control
temperatures, starting at setting 1, days
1 to 5, and finishing at setting 6, days 6
& 7, (see figs. 4 to 6). Pressing PROG
while setting 6, days 6 & 7 is shown
returns the TP5E to RUN mode.

The following table shows the factory pre-set programme,
which may be re-instated at any time by performing a
RESET.

Days 1 to 5 (Weekdays) Days 6 & 7 (Weekend)

Setting Time Temp. Setting Time Temp.

1 6:30 20 1 7:00 20
2 8:30 15 2 16:00 21
3 11:30 20 3 23:00 15
4 13:30 15 4 0:00 15
5 16:30 21 5 1:00 15
6 22:30 15 6 1:59 15

The factory pre-set programme for days 6 & 7 (Saturday
and Sunday) provides full heating throughout the day
until 23:00, after which the 15°C may be raised manually
to the level required using the s button. The manual
over-ride will last for up to one hour until midnight (0:00)
after which it can be used up to twice again to provide full
heating until 1:59 if required.

CHANGING THE SETTINGS

While reviewing the settings the switching time and
control temperature may be changed using the + and ­(time) and s and t (temperature) buttons.

When changing the switching times it is not possible to
set the times out of sequence.

This important feature works like this:
Both number 1 time settings can be placed at any time of

the day, although they would usually be in the morning.
Each of the time settings 2 to 6 can only be placed

between the previous setting and 1:59.
When using the - button to change settings 2 to 6 the

button stops responding when the previous setting time
is reached. While using the + button to change settings
2 to 5, as later settings in the sequence are reached the
time continues to advance, (until 1:59 if the button is held
down), and all later settings reached are then changed to
the same time as the one being set.

Should this happen unintentionally and settings 2 to 6 are
all at the same undesirable time, use the PROG button to
get back to setting 1, days 1 to 5, then review and change
all the times and temperatures to the required settings. If
any times are intentionally set to the same time then the
temperature associated with the higher setting number
will be used to control the room temperature.

NOTE

While in programming mode (but not in time setting), if no
buttons are pressed for 2 to 3 minutes the TP5E
automatically returns to RUN mode, and the programme
set up to that moment will be active. This programme may
not be the one intended so review the settings again,
before returning to RUN by pressing PROG at setting 6,
days 6 & 7.

EVERYDAY OPERATION

When all twelve time/temperature
settings have been checked and/or
altered, ensure the TP5E is in the RUN
mode, with the colon blinking, (see fig.

Fig. 7

7), before sliding the cover shut.

TIME OR TEMPERATURE DISPLAY

The TP5E will always display the time
and required temperature after a
RESET. Once the switching times and
temperatures have been set and the

Fig. 8

unit returned to the RUN mode, the
actual room temperature can be displayed instead of the
time. To change between time and temperature display
press the + and - buttons together. Fig. 8 is a typical
temperature display showing the actual temperature, the
required temperature, and flame and thermometer
symbols. The flame symbol appears in either time or
temperature displays when the TP5E is calling for heat.

*NOTE

The TP5E will only provide frost protection to the area in
which it is fitted. It WILL NOT provide frost protection in
unheated areas, and may not provide frost protection in
heated areas not controlled directly by the TP5E.

BATTERY REPLACEMENT

When the batteries approach the end
of their life, a battery symbol blinks in
the display (see fig. 12). When this
symbol appears both batteries should

Fig. 12

be replaced with high quality alkaline
cells. 15 days after the symbol appears the TP5E will
switch off. While the battery symbol is blinking the batteries
may be changed without loss of time or programme.
Have the new batteries unwrapped and ready, slide the
battery cover fully off to the left, remove the old batteries
and fit the new ones WITHIN FIVE MINUTES. Replace
and close the battery cover. The TP5E will continue to
function according to the automatic programme. Should
the display ever become blank during normal operation
the batteries will have to be renewed, the unit RESET,
and the time, day and programme re-set as required.

MANUAL OVER-RIDE
The programmed control temperature

may be changed temporarily using the
s and t buttons until the required
temperature is shown. An s or t

Fig. 9

arrow will appear in the display as a
reminder that the programmed setting has been over­ridden, (see fig. 8 again). This over-ride is cancelled at
the next programmed switching.

WEEKEND into WEEKDAY OVER-RIDE
To use days 6 & 7 settings during any of days 1 to 5 press

the s and t buttons together, (see fig. 9). This over-ride
is cancelled by selecting Constant Temperature Control
(see below) or when the time reaches 2:00.

CONSTANT TEMPERATURE OVER-RIDE
To set the TP5E to control at a constant temperature of

5°C press the s and t buttons together, once from
Weekend/Weekday over-ride or twice from RUN mode.

The required constant temperature
may now be set using the s and t
buttons, and can be anywhere in the
range 5°C to 30°C. At 5°C a snowflake

Fig. 10

symbol appears in the display (see fig.

10) indicating frost protection mode*;
at all other temperatures an s arrow
appears (see fig. 11) indicating a
constant temperature selection. This
over-ride is cancelled by pressing the

Fig. 11

s and t buttons together.
