FEATURES

● Controls central heating systems to provide different room

temperatures up to 6 times a day.

● The TP3 and TP5 have one programme for Monday to Friday,

with a different programme for Saturday and Sunday.

● TP2 and TP3 have minimum temperature setting of 16°C, ideal

for use in elderly persons accommodation.

● Setting the TP4 and TP5 to the lowest temperature will

effectively switch off the heating, whilst providing frost protection
for the controlled area.*

● A constant low temperature is easily selected while away from

home, for example, when on holiday.

● Battery operated. Ideal for low voltage control circuits, e.g.

some combi-boilers, as well as for mains voltage circuits.
Batteries can be changed without loss of programme.

● Wiring conversion chart for common room thermostats included.

* This low temperature selection should not be used for Frost

Protection if some parts of the heating system are in an exposed
location.

INSTALLATION INSTRUCTIONS

NEW INSTALLATION

Choose a fixing position where the thermostat will sense the room
temperature without being affected by draughts or heat sources
such as radiators, open fires or direct sunlight. Fix at height of
approximately 1.5 metres from the floor.

Cable entry is from behind if fitted to a single gang flush box, or
from above, below or from the left if surface fixed cable is used.
Fig.1. shows fixing hole dimensions and the clearance required for
the removal of the sliding cover, and for air flow over the sensor.
Standard M3.5 screws are used to fix the thermostat to a flush box,
or No.6 woodscrews and wall plugs of adequate length should be
used for surface fixing.

Fig.1. Fixing centre and clearances.

REPLACING AN ORDINARY ROOM THERMOSTAT

Switch OFF the power to the central
heating system.

Carefully note which wire colours are
connected to which terminal numbers
of the existing thermostat.

If the existing thermostat has no
indication of the numbers of each of
its terminals then a qualified electrician
should be called before proceeding
any further.

Remove the existing thermostats
mounting plate from the wall, and
prepare the wall to receive the
Programmable Room Thermostat. Refer to Fig.1. for dimensions.
Connect the wires to the new thermostat referring to the wiring
conversion chart overleaf.

NOTE:

Some existing thermostats will have a Neutral wire and/or an Earth
wire connected. These wires must NOT be connected to the new
terminals, but made electrically safe and coiled in the recess at the
back of the new thermostat. If in any doubt about the function of every
wire connected to the existing thermostat, call a qualified electrician for
advice.

further left to reveal the batteries. Remove
the paper insulator from between the
batteries and contacts. Reset the unit as
described below. The blank display changes
to that shown in Fig.3. (if the actual air
temperature in proximity of the unit is higher than 16°C the flame
symbol will not be displayed. The day will only appear on models
TP3 and TP5.) Slide the battery cover to the right but leave the

buttons visible

.

RESET

The unit may be reset to 12:00PM (MO) and the factory set
programme by pressing and holding down the four buttons,

temperature s and t, time + and -, until the display goes blank.

SETTING THE CLOCK

Press the PROGRAMME button once; the colon is no longer
flashing, (see Fig.4.). Use the + and - button to set the time. Hold
down a button to change the time quickly; press and release a
button to change the time by one minute. When the time and AM
or PM are correct, press the PROGRAMME button to start the
clock. On models TP2 and TP4 "Set Day" (Fig.5.) does not occur.
If you have a TP3 or TP5, now only the day and the colon are on
display, (Fig.5.). Use the + or - button to select the correct day.

Press PROGRAMME to display the first setting (Fig.6.).

REVIEWING THE EXISTING SETTINGS AND
PROGRAMMING YOUR OWN

Now each press of the PROGRAMME button shows, in, turn, the
set times, (six with the TP2 and TP4, twelve with the TP3 and TP5),
together with their associated control temperatures. Figs. 6 to 8
show the display of various settings in the sequence. The time and/
or temperature of each setting may be altered to your own
requirements using the + and - (time) and s and t (temperature)

buttons.
