OPEN WINDOW DETECTION FEATURE
Your room thermostat measures sudden temperature changes in your house with its open window detection feature and prevents unnecessary energy consumption by turning off the heating/cooling unit. The room thermostat is switched to heating mode while the detection is active. If a decrease in room temperature of more than 5 degrees is detected within 15 minutes, the room thermostat switches to the alarm state and turns off the heating system. The heating unit remains switched off for 10 minutes unless manual intervention is performed on the room thermostat. A warning appears on the mobile application that an open window has been detected. The heating unit is activated at the end of 10 minutes. If the room thermostat detects that the window is closed, the heating unit continues to work.

ROOM THERMOSTAT WORKING LOGIC
Heating Mode
Your room thermostat takes the average room temperature of the last 40 seconds as a 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 the last 40 seconds as a 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 3 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 does 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 3 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. 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
