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 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 unit should work for
What is the difference?
In non-TPI room thermostats, the heating unit works and stops continuously until it exceeds the set temperature value. If the set temperature drops below a certain amount, the heating 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 the last 40 seconds as a 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.

Your Room Thermostat sends the last status signal to the Receiver every 6 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 cases where the electricity comes back after a power failure, the Receiver do not operate the heating/cooling unit until the ‘operate’ signal reaches 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

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.

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 qualifiedpersons. 2×0.75 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.
