Siemens Connected Home is a home automation system designed to make life easier while contributing to a more sustainable future. The ecosystem includes smart radiator heating, which combines comfort and energy savings.

The Siemens Connected Home set, offered at a favourable price, includes everything you need for zonal radiator control, including a relay switching unit for controlling the heat source. It minimizes acquisition costs and significantly simplifies the purchase of smart heating control. You can acquire the components in a few minutes, ensuring that nothing is missing. Once the set arrives, you can immediately start with smart heating. Installation and setup are easy to do yourself thanks to a simple video guide. 

The set includes a ZigBee router, 8 smart radiator heads, and a relay switching unit compatible with gas boilers, heat pumps, zone valves, pumps, domestic heat exchange stations, flow water heaters, and small hot water heating systems. All components are wirelessly connected using ZigBee communication (installation does not require structural modifications) and can be controlled from anywhere and anytime via an app on a smartphone or tablet.

The Siemens Connected Home smart heating system is developed for heating residential and commercial buildings. For larger applications where stronger ZigBee reach is required, you can use an additional switching unit or a router as a signal repeater.

The radiator head SSA911.02ZB has an integrated PI controller to achieve a constant radiator temperature, a temperature sensor, a window open detection function, frost protection, and a child safety lock.

Each head package includes 2 AA batteries, adapters for Danfoss RA, RAV, RAVL valves, and screws for their attachment. If you need to connect the head to a radiator valve other than M30x1.5 or Danfoss RA/RAV/RAVL, use one of the adapters/reducers for radiator valves. Our article from the advisory section can help you choose the right reducer for radiator valves: How to choose the right reducer for radiator heads?

This set includes

• 1x GTW100ZB ZigBee router
• 1x RCR110.2ZB Wireless relay switching unit
• 8x SSA911.02ZB Thermoelectric actuator

How to set up and install your Connected Home system? Watch the following videos and you will immediately know how to proceed.

You can easily download the Connected Home app from Google Play or App Store.

Wireless relay switching unit RCR110.2ZB

The switching unit is designed for switching the boiler or circulation pump in the heating system. Its main purpose is to ensure sufficient hot water for heating. The unit has two volt-free relay contacts, so it can be used to control both the heat source and the hot water source simultaneously. It is powered by a cable, but communication is via the ZigBee protocol. In addition to switching the boiler, it can also serve as a ZigBee signal repeater from the ZigBee router.

ZigBee router GTW100ZB

The router creates a ZigBee network in the household connecting the family of Connected Home products. It is also connected to the internet (via Ethernet or wirelessly) and serves as an intermediary between heating devices and the control mobile app. It is powered by a cable.

Thermoelectric actuator SSA911.02ZB

The actuator is designed for heating regulation and radiator valve control. It controls the flow of heating water through the radiator. It features a thermal sensor and an integrated PI controller. It is battery-powered (battery life approx. 2 years). It communicates wirelessly via ZigBee communication, but can also be set manually. It is equipped with an automatic adaptation function that ensures optimal lift and force necessary for valve control.

What are the advantages of the wireless Connected Home system?

The new wireless ecosystem from Siemens for smart heating offers very easy implementation into existing home heating systems. No structural interventions or modifications are needed for installation. All system elements communicate via wireless ZigBee communication. The ZigBee router connected to the internet then allows communication with the mobile app on a smartphone. Thus, heating in your home can be controlled from anywhere and at any time.

The ecosystem saves on operating and energy costs. It can work with different electricity tariffs and efficiently plan water heating. It can simultaneously regulate multiple individual zones in one household. For each room, it can create a program with a temperature tailored to its occupants or based on its usage schedule.

In total, up to 100 different Connected Home system devices can be connected to the ZigBee router, including up to 32 actuators. In the future, many expanding Connected Home devices are planned, including thermostats, smart sockets, underfloor regulators, flood sensors, motion sensors, and more.
