4. Setup and Installation
4.1 Installation Location
Install the thermostat in a location that accurately reflects the room temperature, away from direct sunlight, drafts, or heat sources. The thermostat is designed for universal cassette installation, fitting both 86x86mm square boxes or European 60mm round boxes.
4.2 Wiring Instructions
WARNING: Disconnect power at the circuit breaker before proceeding with wiring.
- Carefully remove the front panel of the thermostat to access the wiring terminals.
- Connect the power supply wires (95-240V AC, 50-60Hz or 24V DC/AC, 50-60Hz) to the designated terminals.
- Connect the heating system wires (e.g., underfloor heating cables or boiler control wires) to the appropriate load terminals. The thermostat supports a current load of 5A for water heating/gas boilers or 16A for electric heating.
- Connect the NTC3950, 10k sensor to its dedicated terminals. This sensor measures the floor or room temperature.
- Ensure all wires are securely fastened. The terminals are designed for wire sizes 2x1.5mm² or 1x2.5mm².
- Mount the thermostat base into the wall box using the provided screws.
- Reattach the front panel to the thermostat base.
