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.

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.
