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
Before starting, power off the device connected to the Room Thermostat and make sure that the energy is cut off.

As shown in the picture, 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.

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 “On/Off”button for 3 seconds.
Press the “On/Off” button until the “ CRL ” menu appers. In order to see the desired temperature, set the temperature difference by press the “Temperature Adjustment Buttons”. This value can be arranged between “-8oC” and “+8oC”.
To save the settings and exit, press the “On/Off” button until the device turns off.

Note: Recommended tempreture calibration is “0.0oC”.

FACTORY SETTINGS RESET

You can reset your Room Thermostat to its default factory settings.
This operation resets the mode temperature values, calibration setting and heating/coling modes to factory setting. To reset your Room Thermostat to factory setting:

While your device is turned off, press and hold the “On/Off”button for 3 seconds.
Press the “On/Off” button until “ ” menu appears.
While in the “ ” menu, select the “ ” option by using “+” or “-” buttons and press the “On/Off” button.

TPI ROOM THERMOSTAT WORKING LOGIC

Your Room Thermostat works with the TPI algorithm. Room Thermostats using TPI technology predict when the temperature of your home will rise above or below the set temperature and turn the heating / cooling unit on and off accordingly. This ensures that your home stays at the temperature you set without maximum deviations up and down.

What is TPI?
TPI technology is designed to ensure that you get the best possible energy efficiency from your heating / cooling system. It measures and applies the best possible timings to deliver and maintain your home at the set temperature level.

How does TPI work?
Thanks to the advanced artificial intelligence technology found in the software, it adapts to the temperature change of the environment in which it is located. By creating a general temperature map of your home, it learns how long it takes to reach the desired room temperature and how to maintain this temperature. In this way, it provides minimum energy consumption by calculating how long your heating / cooling unit should work for.

What is the difference?
In non-TPI room thermostats, the heating / cooling unit works and stops continuously until it exceeds the set temperature value. If the set temperature drops below a certain amount, the heating / cooling unit will work again. This creates greater temperature fluctuations and less energy control. TPI Room Thermostats, on the other hand, provide higher savings and comfort compared to On/Off room thermostats with the advantages it has.

Heating Mode
Your room thermostat takes the average room temperature of last 40 seconds as basis. With the TPI algorithm in the product by creating a general temperature map of your home, it learns how long it takes to reach the desired room temperature and how this temperature is maintained. Thus, it ensures that the room temperature remains within a certain range.

WHAT TO KNOW ABOUT TPI ROOM THERMOSTAT

 If the placement of the TPI Room Thermostats is changed, the
learning process will restart. The learning process should be
considered as 7 days.
 If the TPI Room Thermostats are de-energized (battery
replacement), the learning process will restart. The learning
process should be considered as 7 days.
