INTRODUCTION

INTRODUCTION
This thermostat can replace most common
residential thermostats and is designed to be used
with electric, gas or oil heating control system or
cooling system.
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/cool on/off
control. The Control Centre serves as user interface
and temperature sensing/control. The two units are
linked by Radio Frequency.
The advantage is that user can put the Control
Centre nearby and can read/control the temperature
of the actual living area.

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 filing 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 fixing 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 fan (heat/cool call
indicator) should appear on the bottom left 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 fan (heat/cool call
indicator) should disappear and the green LED should
switch off
5. If at step 3 the LED is not illuminated, Press Down
button to adjust the set-point temperature to be lower
than room temperature to stop the unit calling for
heat. 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’ section of this
manual, then repeat steps 1 to 4.
Note that the RESET button on the Control Centre
should be pressed after altering the address code.

Multiple Thermostat Installations
Please note, if using more than one Thermostat
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 unit
following the ‘RF Address Code Setting section of this
manual. Each thermostat 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 thermostats 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.

I have each day a setting am and a setting pm. I wish to manually switch on the heating at other times of the day when I feel it is necessary, and switch off the heating after a short time, all without upsetting the set points already set. How can I do this ?

How do I open the thermostat to change the battery? It looks as though it should just pull apart, but something is holding it together in the middle of the top side and I do not want to force it.
