Programmable Thermostat
ARATON 2100 TX 1

I. INTRODUCTION
This thermostat can replace most common
residential thermostat and is designed to be used
with electric, gas or oil heating control system or
cooling system.
Unlike those ordinary single unit design thermostat,
AURATON 2100 TX 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 Center serves
as user interface and temperature sensing /
control. The two units are linked by RF.
The advantage is that user can put the Control
Center nearby and can read / control the
temperature of really the living area.

II. INSTALLATION OF RECEIVER
Caution:
1. The appliance can only be mounted on dry indoor
places
2. A suitable fuse with a rating not exceeding 20A,
should be in the power line
3. Observe the nation regulator for the wiring
4. Qualified electrician is recommended for
installation and servicing
This thermostat has been designed for simple and
quick installation requiring only a few tools. Only
the Power Control Unit need to be installed.
2.1) Required Material
Hammer
Masking tape
Screwdriver
Drill and 3/16" drill bit (if not installed on a junction
box)
2.2) RF Address Code Setting
If there is another user nearby, e.g. in the next
house, installs the same AURATON 2100 TX unit,
your receiver may be fault triggered by his/her
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 Receiver, simply push
up one or more of the 5 dip switch levers
2. To adjust address code of Control Center, open
the housing of transmitter unit. See battery
replacement section on how to open the
housing

3. Remove one or more of the jumper cap as
shown in the diagram below.
Caution :
1. Address code of Control Center must be the
same as address code of Receiver. For any
jumper cap removal of address code # in Control
Center, same address code # of Receiver must
be put to the UP position.
2. Disconnect AC power and remove batteries
before adjusting address code.
Remove one or more of
the jumper cap to adjust
RF address code.
Address code # 1 - 5,
from left to right

2.3) Removing your old thermostat
CAUTION: to avoid electric shock, turn off 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
You may have to pull extra hard.
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.
2.4) Wire Labeling
1. Disconnect and identify each wire.
2. You may wish to tape the wires to the wall to
keep them from slipping through the hole in the
wall. If the hole in the wall is larger than
necessary, fill it in order to prevent hot or cold
air to penetrate the thermostat. In this manner,
the thermostat will behave perfectly.

Input Remove
the front
housing
Push and hold
internal lock by
a screw driver

Inside the Control Center after back housing is
removed, you can find the DIP switch. These three

as the following diagram.
Set the DIP switch (position 3)
3.2) Temperature Span Selection
Span is the temperature difference between the
turn on temperature and turn off temperature. For
example, in heating system, if you set temperature
to 20°C and span to 1°C, the heater will operate
when the room temperature drops to 19.5°C and
turns off when the temperature rises to 20.5°C. Set
the DIP switch (position 1 & 2) according to your
selection of temperature span as the following
diagram.
