INTRODUCTION
This thermostat can replace most common residential thermostats
and is designed to be used with electric, gas or oil heating control
systems.
Unlike ordinary single unit design thermostats, this is a new type of
thermostat separating the operational functions into two units. The
Receiver serves for wiring connections and heat on/off control. The
Control Centre serves as user interface and temperature sensing/
control. The two units are linked by Radio Frequency.
The Receiver is easily installed using the Industry Standard back
plate supplied (for mounting purposes only as no wiring is required
when installing the control centre).
The back plate can be mounted directly to the wall surface.
Installing & Wiring the Receiver
Caution: Switch off the electric source before installing the receiver.
We recommend that the installation be performed by trained
personnel.
1) This must be 230V AC and fused at 13 amps max.
2) Select a suitable indoor location free from water and moisture.
3) The receiver should not be shielded from the RF signal in any way,
follow ‘Testing the RF Transmission’ section (PAGE 7

2
GB
) of this manual before deciding on a nal location for the receiver
and control centre units.
4) The Receiver should be mounted in a suitable location that is both
accessible for the connection of mains and control wiring, and
allows good reception of the RF signal. The Receiver needs a 230V
AC mains supply to operate, and this should be fused appropriately
(13A max.). The Receiver should be
mounted in a location where it will
not come into contact with water,
moisture or condensation.
The Receiver On/Off switch is
accessible from the front face of the
Receiver, as shown in this picture:
On the front cover of the Receiver you
will see that there is the On/Off switch and two Light Emitting diodes
(LEDs). The switch allows you to turn off the Receiver if necessary
to prevent it calling for heat. The top LED (red) will illuminate when
the switch is in the ‘On’ position and the unit is receiving power. The
bottom LED (green) illuminates when the Receiver unit is receiving
a heat call transmission from the Control Centre.

The wiring terminals and RF Address Code
setting DIP switches are located on the rear
of the Receiver, as shown in this picture:

Multiple Thermostat Installations
Please note, if using more than one Receiver in the same
installation, be sure that there is at least a 1 metre gap
between receiver units to avoid RF interference.
When installing multiple thermostats you should ensure that you
assign different address codes for each Receiver following the ‘RF
Address Code Setting’ section of this manual. Each Receiver should
be introduced to the installation one at a time with all other receiver
units switched off, also make sure that the batteries are removed
from all other Control Centres.
Install each unit following the ‘TESTING THE RF TRANSMISSION’
section of this manual. Once you are happy with the operation of one
unit you may install the next. Once all Receiver ‘s are installed, if one
unit then seems to function abnormally, try changing the address code
of the control centre & its corresponding receiver again taking care
that the new code given is different to all others in the installation.
The control centre sends RF On/Off signals every 10 min to ensure
the receiver is in the correct state. If for some reason the 1st RF
signal is interrupted you may notice the control centre has started/
stopped calling for heat but the receiver hasn’t switched. Simply wait
10 minutes until the next RF signal is transmitted and the receiver
unit should switch.

GB
RF Address Code Setting
If there is another user nearby, e.g. in the next house, your receiver
may be fault triggered by their transmitter. You may select a different
RF address code to prevent this. The receiver can only respond to
RF transmissions with the same address code setting as its own
address code.
1. To adjust address code of Receiver & Control Centre, simply push
up or down on the 5 dip switch levers. The leavers are numbered
1 to 5 from left to right.
Note :
1. Set dip switch on receiver in same ON position as in transmitter.
ON position is marked on each part shown in picture.

TESTING THE RF TRANSMISSION
It is important to site the Receiver and Control Centre in locations
where the RF signal cannot be interrupted. The receiving range
between Control Centre and Receiver is 60M in open area. Many
factors can affect the RF transmission, shortening the operating
distance e.g. shielding by thick walls, foil back plasterboard, metal
objects such as ling cabinets, general RF interference etc, However,
the range is enough for most household applications.
It is advisable to test the RF transmission from the intended Control
Centre location to the Receiver location before xing the Control
Centre to the wall.
1. Press UP button until the set-point temperature is higher than room
temperature by a few degrees.
2. Wait for a few seconds. The animated fun (heat call indicator) should
appear on the bottom right of the LCD on the control centre.
3. Check the green LED on the receiver unit. It should be
illuminated.
4. Press Down button to adjust the set-point temperature to be lower
than room temperature. Wait for a few seconds. The animated ame
(heat call indicator) should disappear and the green LED should
switch off.
5. If at step 3 the LED is not illuminated, press RESET and try to place
the Control Centre closer to the Receiver, repeating steps 1 to 4.
6. Alternatively you can try and alter the address code following the
‘RF Address Code Setting (page 5) of this manual, then repeat
steps 1 to 3.
Note that the RESET button on the Control Centre should be pressed
after altering the add ress code.

INSTALLAING THE CONTROL CENTRE
Select a suitable location for the control centre. The location of the
control centre can greatly affect its performance. If it is located where
air circulation cannot reach, or exposed to direct sun light, it will not
adjust the room temperature properly.
To ensure proper operation, the control centre should be installed
at an inside wall with freely circulating air. Find a place where your
family is usually occupied.
Avoid close proximity to heat generating appliances (e.g. TV, heater,
refrigerator) or exposed to direct sunlight. Do not install near a door
where the thermostat will suffer from vibration.
Using the template provided, drill two ø6mm holes in the wall. Insert
the wall anchors and tighten the left screw with 3mm clearance. Fix the
control centre by putting it over the screwhead and slide it rightward
(note the keyhole-like opening at the back of the thermostat). Tighten
the remain screw to lock it in place.

Note: If the wall is made of wood, there is no need to use the wall
anchors. Drill two ø2.7mm holes instead of ø6mm.

USING YOUR NEW CONTROL CENTRE
The following procedures show how to operate the control centre. It
is recommended that you follow the instructions and try to operate
once before connecting it to the heating or cooling system.
1, Start
There is a sliding door on the right half of the thermostat. If you open
the door, you can see some buttons. This door is removable for the
replacement of batteries. After opening the door, you can ip the door
up or down to see the battery compartment.
The control centre is operated by two AA alkaline batteries. Please
remove the front cover and install two new batteries.
When the batteries are installed, the control centre should be
operating and you can see the LCD active. If the control centre does
not work properly, please check the batteries for wrong polarities and
press the reset button by using a ball-point pen.

Output-On indicator may activate after a few seconds, depending
on different situations.
II, Do not use a pencil to push the reset button. The graphite residue of
a pencil can cause a short circuit and damage the control centre.

Temperature mode
You can see ☼ and

on both the buttons and the LCD. ☼ means
comfort temperature and

means economy temperature. These
two temperatures are user changeable. Furthermore, there is a xed
defrost temperature (7°C) indicated by  on the LCD. Throughout the
operation of the thermostat we will refer to them as comfort, economy
or defrost temperature instead of numeric values.
Program
This is a programmable thermostat. It can automatically adjust the
room temperature to a comfortable level when you are at home, and
lower it to save energy when you go out or sleep. What you have to
do is to program the thermostat so that it knows when to raise the
temperature. There are altogether nine programs contained in the
memory of the thermostat. Six of them are preset in the factory and
the remaining three are user changeable.
Manual override
If you want to change the temperature temporarily and do not want
to alter the programs you have set, you can simply touch a button to
override the current program.
