TLX1010 RF Digital Room Thermostat

TLX1010 RF Digital Room Thermostat
What is a room thermostat?
Installation
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.
NB. All installations should be carried out by a
competent person and in line with current wiring
regulations
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 18oC – 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.

Route wires behind the wall to a suitable 35mm
flush mounted dry lining box or wall box.
2
Connect wires to the receiver in accordance
with the wiring diagram shown on page 2 and the
current Wiring Regulations.
3
Position the receiver into the wall box and tighten
the screws.

Before re-connecting to the mains supply ensure
that an appropriate fuse is fitted to the circuit.

WARNING
The cover must not be removed unless the
thermostat is isolated from the electrical supply.

Setting
The TLX1010 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.
The TLX1010 is a radio-frequency digital electronic room
thermostat and receiver with Economy mode (night
setback) and Chronoproportional control (TPI).
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.
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 thermostat has two options; ‘Set back’
(Economy) mode and normal (Comfort) mode.
When the K Terminal of the receiver is activated,
usually by a timer connecting the K Terminal to the
Neutral of the 230V supply, the thermostat runs in
‘set-back’ which is Comfort mode less 5°C. If there is
no feed to the K Terminal, the thermostat runs in
normal Comfort mode.
For fixed wiring only
Disconnect mains supply before fitting receiver, or
removing cover. A switch having a contact separation of at
least 3mm in all poles must be incorporated in the fixed
wiring as a means of fully disconnecting the mains supply.

The Sunvic TLX1010 RF electronic room thermostat is a
Chronoproportional or TPI (Time Proportional Integral)
control product as defined in Building Regulations, which
makes 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 TLX1010
thermostat can make a great contribution to cutting home
energy bills.
Jumper Switch Positions
The jumper switches inside this thermostat are used to
control the Chronoproportional (TPI) function.
Always ensure the mains supply is disconnected before
removing the thermostat cover from the backplate.

Linking the thermostat to the receiver
Press install button on receiver for 10 secs. The green LED
should flash. Next, hold down SET button on thermostat for
3 secs.) ) ) symbol flashes three times. The green LED on
receiver should go off. The receiver is now connected via
RF to the thermostat.
Raising the SET temperature above the room ambient
temperature will cause the thermostat to demand heat and
the red LED should come on. Lowering the SET
temperature below room ambient will cause the thermostat
to be satisfied and the red LED to go off.
To operate manually, press the TEST button on the
receiver (the green LED comes on) then press the
INSTALL button (the red LED comes on) and the relay
switches to demand heat. To switch off manually, repeat
the above process.
Please note, when configured for COOL mode, i.e.
Jumper K 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. K 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.
