Auto-Adapt Feature
The Auto-Adapt function optimizes the heating system's operation to ensure the desired comfort temperature is reached precisely at the scheduled time. It activates heating in advance (10 to 50 minutes) if the current room temperature is lower than the comfort temperature for the upcoming program. The earlier the heating starts depends on the difference between the current and programmed temperatures.

Wiring Diagrams
Thermostat T105 Wiring Diagram
The T105 thermostat connects to the heating system via a voltage-free relay. Connections typically include:
- COM: Common terminal
- NO: Normally Open terminal
- L: Live connection (if applicable for power, though T105 is battery powered)
- N: Neutral connection (if applicable for power)
The diagram shows connections for the thermostat (COM, NO) and the boiler/heating system. The maximum load for the T105 is 5(3) A.
Thermostat T105RF Wiring Diagram
The T105RF system consists of a thermostat and a receiver (e.g., RXRT505). The receiver is powered by 230V AC.
Thermostat T105RF Connections: Typically battery powered, communicates wirelessly with the receiver.
Receiver RXRT505 Connections:
- L: Live power input (230V AC)
- N: Neutral power input (230V AC)
- COM: Common terminal for the relay output
- NO: Normally Open terminal for the relay output
The diagram shows the receiver connected to the 230V AC power supply and the heating system (boiler/control unit) via the COM and NO terminals. The maximum load for the receiver is 16(5) A.
Advanced Settings
Changing Communication Code (T105RF)
It is recommended to change the factory-set communication code to a unique one to prevent interference from other wireless devices.
Use DIP switches numbered 1-5 located inside the thermostat to change the communication code. Ensure the DIP switches are set to the same random positions on both the thermostat (transmitter) and the receiver.
After changing the communication code, press the [RESET Button] to apply the changes.
Service Parameters
Service parameters are adjusted using DIP switches located inside the thermostat.
Heating / Cooling Mode Selection:
Use DIP switch #3 to select the operating mode:
- ON (Upper Position): Thermostat operates in Heating Mode.
- OFF (Down Position): Thermostat operates in Cooling Mode.
Hysteresis (Span) Control:
Hysteresis (Span) is adjusted using DIP switches #1 and #2. The available settings are:
| DIP Switch 1 | DIP Switch 2 | Hysteresis (Span) |
|---|---|---|
| ON | ON | 0.4°C |
| OFF | ON | 0.8°C |
| ON | OFF | 1.4°C |
| OFF | OFF | 1.4°C |
