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 or left. This value can be arranged between "-8^oC" and "+8^oC".
• To save the settings and exit, press the "On/Off" button until the device turns off.

Note: Recommended tempreture calibration is "0.0^oC".

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.

ROOM THERMOSTAT HYSTERESIS NEGATIVE MENU

Hysteresis negative 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 negative value is -0.5°C, if the room temperature goes below 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°C, if the room temperature goes below 21.5°C, on heating mode your heating unit will start working; on cooling mode your cooling unit will stop working. In order to change the hysteresis negative setting:

• Press the button for 3 seconds while your device is off.

ROOM THERMOSTAT WORKING LOGIC

Heating Mode

Your room thermostat takes the average room temperature of last 40 seconds as basis. If the room temperature goes above the hysteresis positive temperature value you set, your Room Thermostat will stop the heating unit. If it goes below the hysteresis negative temperature value, your Room Thermostat will start the heating unit. Thus, it ensures that the room temperature remains within a certain range.

Cooling Mode

Your Room Thermostat takes the average room temperature of last 40 seconds as basis. If the room temperature goes above the hysteresis positive temperature value you set, your Room Thermostat will start the cooling unit. If it goes below the hysteresis negative temperature value, your Room Thermostat will stop the cooling unit. Thus, it ensures that the room temperature remains within a certain range.

Your Room Thermostat sends the last status signal to the Receiver every 10 minutes. Thus, your Room Thermostat and Receiver work synchronously. If the signal cannot reach to the Receiver from the Room Thermostat for 22 minutes, it perceives that the connection is broken and stops the heating/cooling operation for safety reasons. Likewise, in cases where the electricity comes back after a power failure, the Receiver do not operate the heating/cooling unit until 'operate' signal reaches from the Room Thermostat.

However, in this case, if the Room Thermostat continues to operate normally, it will continue to work properly without any need for intervention since it sends a status signal to the Receiver every 10 minutes.

FREQUENTLY ASKED QUESTIONS

• Is my Room Thermostat compatible with my heating/cooling unit?

If your heating / cooling unit has on-off connections, your Room Thermostat is compatible. You can find information about your heating / cooling unit from your heating / cooling unit operating manual or from your heating / cooling unit service.

• How will I connect my heating/cooling unit with my Receiver?

We recommend that the connection between the Receiver and heating/cooling unit should be made by professionally qualified persons. 2x0.75 mm cable is sufficient for the Receiver – heating/cooling unit connection.

Connect one end of the cable pair to the room thermostat connection terminals stated in the user manual of your heating/cooling unit.
Connect the other end of the cable pair to COM and NO inputs of the terminal inside the Receiver as shown in the "RECEIVER WIRING DIAGRAM" section.

The direction of the cable ends does not matter.
