Beállítás és telepítés
1. Elhelyezkedés
A termosztátot körülbelül 1.5 méterrel a padló felett szerelje fel, jó légáramlású helyre, közvetlen napfénytől, huzattól és hőforrásoktól távol. Kerülje az ablakok, ajtók vagy szellőzőnyílások közelét, amelyek befolyásolhatják a hőmérséklet-mérést.
2. Kikapcsolás
Before beginning installation, ensure the power to your HVAC system is completely turned off at the circuit breaker.
3. Remove Old Thermostat
Carefully remove your old thermostat from the wall. Take a picture of the existing wiring connections before disconnecting any wires. Label each wire with the terminal designation it was connected to.
4. Mount the New Thermostat
- Separate the front cover from the thermostat base.
- Position the thermostat base on the wall, feeding the wires through the opening.
- Mark the mounting holes. Drill pilot holes if necessary.
- Secure the thermostat base to the wall using the provided screws and anchors.
