TLX1009 Digital Room Thermostat
What is a room thermostat?
A room thermostat simply switches the heating system on and off
as necessary. It works by sensing the air temperature, switching
on the heating when the air temperature falls below the thermostat
setting, and switching it off once this set temperature has been
reached.
Turning a room thermostat to a higher setting will not make the
room heat up any faster. How quickly the room heats up depends
on the design of the heating system, for example, the size of boiler
and radiators.
Neither does the setting affect how quickly the room cools down.
Turning a room thermostat to a lower setting will result in the room
being controlled at a lower temperature, and saves energy.
The heating system will not work if a time switch or programmer
has switched it off.
The way to set and use your room thermostat is to find the lowest
temperature setting that you are comfortable with, and then leave it
alone to do its job. The best way to do this is to set the room
thermostat to a low temperature – say 18
o
C – and then turn it up
by one degree each day until you are comfortable with the
temperature. You won’t have to adjust the thermostat further. Any
adjustment above this setting will waste energy and cost you more
money.
If your heating system is a boiler with radiators, there will usually
be only one room thermostat to control the whole house. But you
can have different temperatures in individual rooms by installing
thermostatic radiator valves (TRVs) on individual radiators. If you
don’t have TRVs, you should choose a temperature that is
reasonable for the whole house. If you do have TRVs, you can
choose a slightly higher setting to make sure that even the coldest
room is comfortable, then prevent any overheating in other rooms
by adjusting the TRVs.
Room thermostats need a free flow of air to sense the
temperature, so they must not be covered by curtains or blocked
by furniture. Nearby electric fires, televisions, wall or table lamps
may prevent the thermostat from working properly.
TLX1009 Room Thermostat
The TLX1009 is a digital electronic room thermostat with
Economy mode (night setback) and Chronoproportional
control (TPI). It has Volt-free switching with 2 wire
installation (no need for a Neutral).
Thermostat position: To be placed at a height of 1.5m
from the floor. Do not position on an outside wall, above a
radiator, next to a door, or in direct sunlight. This unit must
be installed by a competent person.
For fixed wiring only
Ensure that the fixed wiring connections to the mains
supply (if used) is via a fuse rated at not more than 3 amps
and a class ‘A’ switch having a contact separation of a
minimum of 3mm in both poles.
Installation
N.B. All installations should be carried out by a
competent person and in line with current wiring
regulations
1. Open the unit by slackening the retaining screw
situated on the bottom edge and hinge carefully
upwards. Disengage the unit from the wall plate
and place it to one side for safe keeping.
2. Fix the thermostat base plate directly to a flat wall
using plugs and No. 6 x 1” screws, or on to a flush
mounting single conduit box type UA1 (BS4662)
using M3.5 x 14 bolts. Ensure the cable used is
double insulation rated for the application load (2
amps max.).
3. The thermostat base plate should be positioned
with a minimum of 70mm clearance all around to
allow adequate air flow.
4. Strip back wire insulation as required and securely
fit wires to terminal block in accordance with the
wiring diagram below. Note an EARTH connection
is not necessary as the TLX 1009 meets the
required double insulation standards.
5. Fit 2 AA 1.5V Batteries as indicated on base of
battery compartment.
6. Fit the unit up to the wall plate by hinging from the
top edge and carefully secure with the retaining
screw.
7. Please ensure this user guide is left for the
householder.
WARNING
The cover must not be removed unless the
thermostat is isolated from the electrical supply.

Setting
The TLX 1009 digital room thermostat is simple to use. The
large Liquid Crystal Display continuously shows actual
room temperature on the top line. Below that the set point
temperature is shown with a larger typeface.
To display the temperature requested (the set point) press
“+” or “-“. Press the middle button marked ‘SET’ to confirm
or just wait 15 seconds to confirm automatically.
Setback Control
This thermostat has two options; MOON often called “Set
Back” (Economy) mode and SUN which is the normal
(Comfort) mode. The MOON mode (Economy) is the SUN
mode less 5°C.
To change mode: Press and hold the “SET” for 3 seconds
to shift to MOON mode ( ). Press and hold the “SET” key
for 3 seconds again to shift back to SUN mode (☼).
Chronoproportional control (TPI)
The Sunvic TLX 1009 electronic room thermostat is a
Chronoproportional or TPI (Time Proportional Integral)
control product as defined in the Building Regulations,
which make boilers operate more efficiently and provide
close accurate control.
Chronoproportional (TPI) room thermostats provide more
accurate temperature control than traditional room
thermostats and uniquely also match boiler firing to the
load on the system, so the boiler operates much more
efficiently. These are due to their TPI (Time Proportional
and Integral) advanced energy saving control. TPI
increases boiler efficiency by adjusting firing duration with
demand and maintains room temperatures around the set
point – an advantage over all other domestic room
thermostats using simple on/off control.
This product can be used on any boiler, with radiator and
underfloor systems, electric heating and zoned heating
systems. Heating and hot water accounts for over 80% of
total household energy usage, so the Sunvic TLX 1009
thermostat can make a great contribution to cutting home
energy bills.

Press any key to illuminate the backlight and it will
illuminate for 15 seconds.
Please note, when configured for COOL mode, i.e
Jumper J 1 in the ON position, the fan, air-conditioning
unit etc, is connected to the ON terminal (and not to
the OFF terminal as it would be if the unit were
configured for Heat).
When configured for COOL and the time delay is
selected i.e. J 2 is in the ON position, the time delay
icon blinks only when the thermostat has been set
previously to demand heat, then turned back to the
lower temperature setting.
Any alterations to the Jumper settings require the
Reset button to be pressed for the changes to be
recognised and stored.
