Notes on engineering and operation
∂
The mounting location should be chosen such that the integrated temperature
sensor can acquire the room temperature as accurately as possible. The SSA955
should not be installed in niches or bookshelves and not behind doors or curtains.
Temperature measurement should not get adversely affected by direct solar
radiation or other heat or refrigeration sources
∂
The permissible temperatures must be observed (refer to ”Technical data”)
∂
For notes relating to engineering and mounting RF devices of the Siemens Synco
living system, refer to Data Sheet CE1N2708en
When mounting the SSA955, ensure that
there is sufficient clearance to replace the
batteries, to press the multifunction button
and to monitor the multifunction LED.

Actuator and valve are joined by a coupling nut with no need for using tools.
The SSA955 is supplied with the stem fully retracted (to facilitate mounting).
Mount the SSA955 first and then insert the batteries.

Prior to commissioning, check to ensure that the SSA955 is correctly fitted to the valve
and that the batteries are correctly inserted.
For more detailed information about commissioning, refer to the Synco living Operating
Instructions.
The SSA955 is maintenance-free.
The system indicates when batteries must be replaced. The batteries are to be inserted
when the SSA955 is mounted (reversed polarity protection).
