Use
● The SSA911.01TH 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 only in combination with Siemens Smart Thermostat
RDS110.R and optionally with wireless repeater RCR114.1.
● One RDS110.R can be paired with up to 6 radiator valve actuators in parallel. Up to 3
wireless repeaters RCR114.1 can be used to extend the range of the network.

Functions
Function Description
Communication The communication protocol used is THREAD.
THREAD is a low-power wireless mesh networking protocol and enables device-to-device
and device-to-cloud communication. THREAD is based on IEEE 802.15.4 radio standard.
Parallel operation Up to 6 actuators can be paired and operated with 1 RDS110.R or RCR114.1
Pairing The pairing process must be started on the Smart Thermostat and via HMI on the
SSA911.01TH
Calibration At first start-up, the SSA911.01TH automatically detects the end positions of the radiator
valve and calculates the available stroke. The actuator uses this information for positioning
between 0 and 100 %
Displaying status
information
Actuator status information is indicated on the display
● Setpoint temperature
● Connection to Smart Thermostat
● Radio signal strength
● Battery status (only active when the battery is low)
● Error codes
Connection test When this function is activated, the actuator sends a signal to the connected Smart
Thermostat. Information about the actuator will be shown on the display of the Smart
Thermostat.
Reset and start
new pairing
The current connection to RDS110.R or RCR114.1 is deleted. A new pairing process to
connect to another Smart Thermostat device starts automatically.
Adaptation to
valve
This function starts a new calibration of the SSA911.01TH to the attached valve.
Factory reset Reset the actuator to factory settings. Any existing connection to RDS110.R or RCR114.1 is
deleted and the stem is retracted.
Firmware version Shows the running version of the firmware.
Back up mode In case of a loss of communication, the internal PI-controller controls the temperature
according to the last setpoint received from the Smart Thermostat using the internal
temperature sensor.
Low batteries When the battery capacity drops to 20 %, the actuator displays the battery symbol as a pre-
warning.
A command is sent to the Smart Thermostat and a low battery indication is shown on the
RDS110.R.
Once the batteries are empty, the actuator sends a signal to the Smart Thermostat controller
and shuts down operation with a minimum valve position of 15 %.
Error codes In case of an actuator malfunction or communication error with the Smart Thermostat, an
error code is shown on the display of the SSA911.01TH. See Error codes [➙ 9]

Error codes
In case of an actuator malfunction or communication error with the Smart Thermostat, an
error code is shown on the display of the SSA911.01TH.
Error codes cannot be acknowledged on the SSA911.01TH. The error code is shown on the
display for as long as the error is active and will disappear once normal status has been
reached.
Error notifications are also sent to the Smart Thermostat and shown on the Smart
Thermostat display. E53 is at first only shown on SSA911.01TH and not immediately shown
on the Smart Thermostat. It will take some time to appear on the Smart Thermostat.
Code Error Cause Measures
Automatic
adaptation failed
● The actuator did not correctly adapt to the valve
or could not detect the end positions of the valve
● The actuator is not connected to a radiator valve
● Check the valve type and stroke
compatibility with the SSA911.01TH and
repeat the adaptation
● Check the mechanical valve connection,
adjust, and repeat the adaption
● Ensure that the valve is working correctly
and that the valve stem is not stuck and
repeat the adaptation
Mechanical valve
actuator error
● The movement of the actuator was too short to
detect the end positions of the valve
● Motor movement failure
● The actuator is not connected to a radiator valve
● The stroke and/or end positions of the valve are
not compatible with the SSA911.01TH
No controller found
– pairing failed
● No RDS110.R or RCR114.1 is available to
connect
● The Smart Thermostat is out of range
● RF chip failure
● Check and adjust the settings on Smart
Thermostat and re-start the pairing
process
● Decrease the distance between the
SSA911.01TH and the Smart Thermostat
and re-start the pairing process
Connection to
Smart Thermostat
lost
● The current connection to the Smart Thermostat
is not available anymore (RF chip failure)
● The paired RDS110.R or RCR114.1 is not
available anymore (e.g. loss of power)
● The Smart Thermostat is out of range
● Check the power supply and availability
of the Smart Thermostat
● Decrease the distance between the
SSA911.01TH and the Smart Thermostat
No new pairing process is required
to resolve E53. The SSA911.01TH
will automatically re-connect to the
Smart Thermostat once the
network is available again.

M
aintenance
The SSA911.01TH is maintenance free.
The actuator and the Smart Thermostat will indicate when replacing the batteries is required
approximately 2 months before the batteries are completely empty and the actuator switches
off.
Replacing the batteries
To replace the batteries, the SSA911.01TH should remain mounted on the radiator valve
and the Smart Thermostat should remain on power and switched on. Replacing the batteries
does not require any tools. For optimal performance, the use of high performance alkaline
batteries is recommended.
1. Remove the batteries
– Open the white battery cover [1]
– Remove the metallic slider [2]
– Take the batteries out [3]
2. Insert new batteries - 2 x LR6 (Alkaline AA) [4]
3. Re-insert the metallic slider [5] and put the white battery cover back on [6]
a The actuator will automatically start a new calibration and after successful calibration will
automatically re-establish the connection to the Smart Thermostat
Unsuccessful pairing or calibration is indicated by an error code on the display (see Error
codes [➙ 9]).
