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]
