Battery Installation
Your thermostat uses two (2) “AA” size batteries to operate. To power-up
the unit, insert two “AA” batteries into the battery compartment of the
front housing. When power is applied for the first time, the display must
show time and the day as well as the room temperature (for example
28.5°C).
If the display is different, press the RESET button. Use a fine probe such
as straightened paper clip to gently push the RESET button.
After installation of the batteries, push back the rear housing to the con-
trol centre and then the stand. Before turning on the main switch of the
system, press the reset button once. The thermostat is ready for use.
BATTERY REPLACEMENT
It is recommended that the batteries be replaced when the display is
showing the battery-low icon. To replace the battery,
1. Turn off the power of the Receiver first.
2. Remove the back housing and stand of the Desktop Unit.
3. Replace the old batteries with 2 new AA alkaline batteries.
4. Replace the back housing and stand.
5. Press the reset button once and then turn on the power switch of the
Receiver.

day to program.
Receiver
- Linked with Control Centre via RF.
- Powered by line voltage only. No battery required.
- Two LED indicators for power and output status.
INSTALLATION OF RECEIVER
Caution:
1. The appliance can only be mounted indoors and in areas free from
any water or moisture.
2. A suitable fuse with a rating not exceeding 13A, should be in the power
line.
3. Observe the national regulations for wiring.

This thermostat has been designed for simple and quick installation
requiring only a few tools. Only the Receiver needs to be installed.
Required Tools
• Hammer • Masking tape • Screwdriver
• Drill and 3/16” drill bit (if not installed on a junction box)
RF Address Code Setting
If there is another user nearby, e.g. in the next house, your receiver
maybe fault triggered by their transmitter. You may select a different RF
address code to prevent this. Receiver can only response to RF coding
with the same address code setting as its own address code.
1. To adjust address code of Control Center Receiver, simply left or right
of the 5 dip switch levers.
2. To adjust address code of Control Centre, open the housing of the
transmitter unit. See battery replacement section on how to open the
housing.
Caution:
1. Address code of Control Centre must be the same as address code
of Receiver. For any on position of address code # in Control Centre,
the same address code # of Receiver must be switched to ON.
2. Disconnect AC power and remove batteries prior to adjusting address
code.
Removing your old thermostat
CAUTION : to avoid electric shock, isolate the power of the heating/
cooling system at the main power box in your home. Read the following
instructions carefully before disconnecting the wires.
1. Turn off your old thermostat.
2. Remove the cover from the old thermostat.
3. Unscrew the old thermostat from the wall plate.
4. Now find the screws attaching the wall plate to the wall, and remove
them. You should now be able to pull the wall plate a small distance from
the wall. Do not disconnect any wire yet, simply locate the wires.
WARNING: After removing the wall plate, if you find that it is mounted on
a junction box (e.g. a box similar to one behind a light switch or electric
outlet), high voltage circuit may be present and there is a danger of
electric shock. Please consult a qualified electrician.
T105RF – WIRELESS THERMOSTAT
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 unit
is a new type of thermostat separating the thermostat function 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 RF.
The advantage is that users can put the Control Centre nearby and can
read/control the temperature of the living area.

Features
Several useful functions and operating modes have been incorporated
to suit a variety of customer needs besides all the features associated
with the state-of-the-art programmable thermostat.
Choosing a Location
Note: for a new installation, choose a mounting location about five feet
(1.5 metres) above the floor in an area with good air circulation and
away from:
1. Drafts.
2. Air ducts.
3. Radiant heat from the sun or appliances.
4. Concealed pipes and chimneys.
Mounting the Receiver onto the wall/junction box
1. Remove the back plate from the Receiver.
2. Mark the holes position.
3. Drill two holes and insert the plastic anchors carefully into the holes,
fasten the back plate to the wall with 2 screws.
4. Connect the wires - see wiring diagram.
5. Push on the wires in the wall.
6. Securely fasten the Receiver to the back plate.

SETTING OF CONTROL CENTRE
Heater/Cooler Selection
Before making any selection in the
control centre, its back housing must
be removed as follows: Inside the
Control Centre after the back housing
is removed, you can find the DIP
switch.
These three switches are used to
control the span and heat/cool sys-
tem. Set the DIP switch (position 3)
according to your selection of heater
system or cooler system as the fol-
lowing diagram.
Temperature Span Selection
Span is the temperature difference between the turn on temperature
and turn off temperature. For example, in heating systems, if you set
temperature to 20°C and span to 0.8°C, the heater will operate when the
room temperature drops to 19.2°C and turns off when the temperature
rises to 20.8°C. Set the DIP switch (position 1 & 2) according to your
selection of temperature span as the following diagram.
