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.
