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.
