●
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
