Application

●The SSA911.02ZB wireless radiator valve actuator is designed to work on radiator

valves from different manufacturers in HVAC applications using M30x1.5 thread. It

operates the valve to control water flow and room temperature.

●The valve actuator works in combination with Connected Home Hub GTW100ZB and

wireless repeater RCR110.2ZB (as an option)

●One Connected Home Hub GTW100ZB can pair with up to 32 radiator valve actuators in

parallel. Wireless repeaters RCR110.2ZB extend the range of the network.

Description

Communication

The communication protocol is ZigBee.

ZigBee is a low-power wireless mesh networking protocol and enables device-to-device and

device-to-cloud communications. ZigBee is based on IEEE 802.15.4 radio standard.

Parallel operation

A single Connected Home Hub GTW100ZB can pair up to 32 actuators.

Pairing

The Connected Home app pairs the devices.

Calibration

The actuator automatically detects the end positions of the radiator valve.

Temperature

Notes

Safety

CAUTION

National safety regulations

Failure to comply with national safety regulations may result in personal injury and property

damage.

●Observe national provisions and comply with the appropriate safety regulations.

WARNUNG

Burns from hot surface

The screw nut that fastens the actuator to the radiator valve can become hot. Risk of burns

from touching the screw nut.

When servicing the actuator:

●Switch off the radiator and allow it to cool down.

WARNUNG

Explosion due to fire or short circuit, even with empty batteries

Risk of injury due to flying parts

●Do not expose batteries to water.

●Do not recharge batteries.

●Do not damage or disassemble batteries.

●Do not expose batteries to temperatures over 85 °C.

WARNUNG

Leakage of electrolyte

Severe burns

●Wear protective gloves to handle damaged batteries.

●In case of contact with electrolyte, rinse eyes immediately with plenty of water. Consult

a doctor.

Observe the following:

●Correct polarity (+/-).

●Use new batteries and inspect for damage.

●Do not mix old and new batteries.

Store, transport and dispose of the batteries in compliance with local requirements,

regulations, and laws. Also observe the instructions of the battery manufacturer.

Switching off the device or loss of communication to the radiator valve actuator may result

in an “undefined state” and quickly drain the batteries.

Do not switch off Connected Home Hub and use a repeater as need to ensure proper

communications.

Mounting SSA911.02ZB is mounted on the radiator valve. There are no preferred mounting positions;

actuator SSA911.02ZB can be operated in all mounting positions. The display must be

clearly visible and the buttons easy to access.

WARNUNG

Falling objects

Overhead installation may result in injury from falling objects.

●Do not install the actuator more than 2 m above ground

●Firmly hand tighten the screw nut clockwise to attach the actuator to the valve or

adapter.

On: Connected to gateway.

Off: Not connected to gateway.

Pairing (inclusion) is active.

●Do not operate the actuators in pairing mode over longer periods; this

quickly drains the batteries.

Perform a factory reset if pairing fails after multiple attempts and then try

again per the documentation.

Remove mode (exclusion) active.

Start adaptation.
