ROOM THERMOSTAT PLACEMENT
Room Thermostat needs to be placed in the room which is used most
frequently. For instance; living room or lounge. Placing the Room
Thermostat in a spot that have air circulation like entrance of a room
or side of window should be avoided. Also anywhere close to
heating/cooling units such as radiator, stove and spots which get
direct sun lights would not be suitable. Room Thermostat needs to be
located above the floor 150 cm height. Few trials may be made to find
the most convenient spot.
BATTERY PLACEMENT
As shown in the picture above, press the screwdriver forward from the space
shown, bend the tabs and separate the front cover. Insert 2 new AAA alkaline
batteries in the battery housing with the correct battery direction. Replace
both batteries at the same time. Then align the front part of your Room
Thermostat to the back and squeeze it towards the back.
Low Battery Warning: When the “ ” icon appears on the screen, it means
“low battery warning”. It is recommended to replace the batteries when this
warning appears.
Warning: When the product is not used for a long period (more than 15 days),
remove the batteries. Otherwise, malfunctions that may occur would be out of
warranty.
Please throw your dead batteries into the waste bin for batteries.
RECEIVER PLACEMENT
The important things to note for the Receiver
placement is avoiding physical contact between the
Receiver and heating/cooling unit, and protecting it
against materials such as liquid, dust etc.
The devices should be placed in order to minimize the damage to the
received and transmitted signals by paying attention to the following points;
The devices should not be mounted on metal surfaces.
The devices should not be installed close to electrical cables and
electronic equipment such as computers and television units.
The devices should not be installed near large metal structures or other
building materials using fine metal meshes such as special glass or
special concrete.
Distance between the Room Thermostat and the Receiver should not
exceed 20 meters or 2 floors.
Receiver must be installed at least 50 cm away from the heating/cooling
unit.
RECEIVER SETUP
First, shut down your heating/cooling unit and your heating/cooling unit's
power source with all electrical current (fuse, socket etc.)
As shown in the connection diagram, connect one end of the
heating/cooling unit connection cable to the COM and the other to the NO
input of the Receiver.
Connect the other ends of the cable -which you connected to the Receiver
to room thermostat connection terminal as shown in your
heating/cooling unit's user manual.
You must first connect the Receiver power cable to the Receiver and then
to the fuse to which the heating/cooling unit is connected.
After completing the cable connection process, firstly turn on your fuse
and then your heating/cooling unit.
By pressing the Receiver's manual usage button for 2 seconds, you should
see the Orange Light blinking on the Receiver. In this way, after making
sure that the heating/cooling unit is operating, press the same button
again for 2 seconds and see that the Orange LED turns off.
Set up the Room Thermostat to pair the Receiver with the Room
Thermostat.

RECEIVER WIRING DIAGRAM
Warning!
Operations within the heating / cooling unit or the electrical installation
must be carried out by professionally qualified persons.
PAIRING THE ROOM THERMOSTAT AND THE RECEIVER
Primarily press the sync button of receiver for 2 seconds and see blinking
green light of receiver.
While your device is turned off, press and hold the button for 3 seconds.
Press the button until the “ ” menu appears.
Then turn up the button to right or left way.
If the pairing is successful, the green flashing LED on the receiver will be
constant.
Receiver and Room Thermostat have been paired to each other.
ROOM THERMOSTAT TEMPERATURE CALIBRATION
Temperature sensors which are used in Room Thermostats are highly
sensitive. You may need to calibrate your Room Thermostat if you would like
to get the same temperature values with other thermometers in your living
space.
While your device is turned off, press and hold the button for 3 seconds.
Press the button until the “ ” menu appers. In order to see the desired
temperature, set the temperature difference by turning the button to right
o o
or left. This value can be arranged between “-8 C" and “+8 C".
To save the settings and exit, press the "On/Off" button until the device
turns off.
o
Note: Recommended tempreture calibration is “0.0 C”.
ROOM THERMOSTAT HEATING / COOLING MODES
Your Room Thermostat has heating and cooling modes. In order to switch
easily between heating and cooling modes:
While your device is turned off, press and hold the button for 3 seconds.
Press the button until the “ ” menu appears.
You can switch between “ ” (heating) and “ ” (cooling) modes by
turning the button to right or left in the “ ” menu.
To save the settings and exit, press the button until the device turns off.
The settings you have made have been saved. Once you turned on your
device, it will operate with the changed settings.
ROOM THERMOSTAT HYSTERESIS POSITIVE MENU
Hysteresis positive factory setting of your room thermostat is 0.5°C. This
value may be adjusted between “0.1°C” and “2.0°C”. While hysteresis
positive value is 0.5°C, if the room temperature goes above 0.5°C of set
temperature, your room thermostat will send a signal to your
heating/cooling unit.
For instance, when you set your room thermostat to 22.0°C, if the room
temperature goes above 22.5°C, on heating mode your heating unit will stop
working; on cooling mode your cooling unit will start working. In order to
change the hysteresis positive setting:
Press the button for 3 seconds while your device is off.
Press the button until “ “ menu appears.
Adjust the operating sensitivity by turning the button to the left or
right in the “ “ hysteresis positive menu.
Press the button until device turns off to save the changes and exit.
Changes have been saved. Your room thermostat will be working
with set operating sensitivity when you open your device.
