T105RF Wireless Communication Setup

Changing the Communication Code

To prevent interference with other wireless devices, it is recommended to change the communication code from the factory default. This is done using DIP switches numbered 1-5 located inside the thermostat. Ensure the DIP switches are set to the same position on both the transmitter (thermostat) and receiver. After changing the code, press the [RESET] ? button on the receiver.

Features and Operation

Auto-Adapt Feature

The Auto-Adapt function optimizes the heating device's operation to ensure the set comfort temperature is reached precisely on time. It activates only when the current room temperature is lower than the comfort temperature programmed for the upcoming period. The earlier activation time (between 10 and 50 minutes before the program starts) depends on the difference between the current and target temperatures.
