Seadistamine ja installimine
1. Asukoht
Paigaldage termostaat põrandast umbes 1.5 meetri kõrgusele hea õhuringlusega kohta, eemale otsesest päikesevalgusest, tuuletõmbusest ja soojusallikatest. Vältige asukohti akende, uste või ventilatsiooniavade lähedal, mis võivad temperatuurinäiteid mõjutada.
2. Lülita välja
Before beginning installation, ensure the power to your HVAC system is completely turned off at the circuit breaker.
3. Eemaldage vana termostaat
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
- Eraldage esikate termostaadi alusest.
- 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.
