Use

●The SSA911.01ZB wireless radiator valve actuator is designed to work on radiator

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

the valve to control the water flow and controls the room temperature.

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

optionally with wireless repeater RCR110.2ZB.

●One Connected Home Hub GTW100ZB can be paired with up to 32 radiator valve actua-

tors in parallel. Wireless repeaters RCR110.2ZB can be used to extend the range of the

network.

Basic functions

Function Description

Communication The communication protocol used is ZigBee.

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

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

Parallel operation Up to 32 actuators can be paired and operated with 1 Connected Home Hub GTW100ZB.

Pairing The pairing process is done via the mobile app Connected Home.

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

Temperature

setting

The setpoint temperature is set via the push buttons on the device.

Third-party valves without adapter

The SSA911.01ZB can operate third-party radiator valves without adapter, provided they

have a M30x1.5 mm connecting thread and meet the following requirements:

Force 90 N nominal

Fully closed x > 9.0 mm

Fully open y ≤14.5 mm

Valve pre-adjustment / kV-limitation

For valve pre-adjustments, refer to the relevant technical documentation on the valves. En-

sure a minimum valve stroke of > 0.5 mm.

Notes

Security

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.

WARNING

Burns from hot surface

The screw nut with which the actuator is fastened on the radiator valve will become hot.

Risk of burns from contact with the screw nut.

When servicing the actuator:

●Switch off the radiator.

●Allow the radiator to cool off.

Siemens A6V12789814_en--

Smart Infrastructure 2022-02-

WARNING

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

Risk of injury due to flying parts

●Prevent the batteries from coming into contact with water.

●Do not recharge batteries.

●Do not damage or disassemble batteries.

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

WARNING

Leakage of electrolyte

Severe burns

●Handle damaged batteries only wearing suitable protective gloves.

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

a doctor.

Observe the following:

●Observe the polarities (+/-).

●The batteries must be new and undamaged.

●Do not mix new and used batteries.

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

tions and laws. Also observe the instructions of the battery manufacturer.

Mounting

The SSA911.01ZB is mounted on the radiator valve. There are no preferred mounting posi-

tions; the actuator SSA911.01ZB may be operated in all mounting positions. Make sure the
