Frequently Asked Questions
Does It Support Multi-Zone Temperature Control?
No — it does not support multi-zone control. The device manages a single furnace zone with manual, programmable settings and Wi‑Fi connectivity; users seeking liberated, flexible climate autonomy should pursue multi-zone systems or external zoning controllers.
Can It Integrate With Smart Home Assistants (Alexa/Google)?
Like a bridge spanning rooms, it connects: the thermostat supports Wi‑Fi and can integrate with smart assistants (Alexa/Google) for liberated, hands‑free control, empowering users to command climate freedom without tethered routines.
Is a Battery Backup Available for Power Outages?
No — there is no battery backup option for power outages. The device relies on corded 230V supply; users seeking resilience must pursue external solutions (UPS or auxiliary battery) to maintain thermostat operation and preserve control.
