Siemens Connected Home Zigbee Smart Thermostats and Controls
Siemens Connected Home Zigbee Smart Thermostats and Control Products
The Siemens CONNECTED series is a smart heating control system that communicates via Zigbee 3.0 and is managed with a mobile app. The GTW100ZB hub connects the system to the internet; the RDZ100ZB controls the boiler via its relay output, while the RDZ101ZB wireless thermostat and the RCR110.2ZB 2-relay receiver control the zones.
The products are designed to work together; a system installation requires the hub and at least one thermostat.

Selection and installation notes

- For accurate sensor readings, the thermostat is mounted approximately 1.5 m above the floor, away from direct sunlight and heat sources.
