For radiator valves with AV… adapters, refer to "Accessories"

kvs = nominal flow rate of chilled water (5…30 °C) through the fully opened valve (H100) at a differential

pressure of 100 kPa (1bar)

The SSA955 can operate without adapter radiator valves of other manufacture provided

they have a connecting thread M30x1.5 mm and meet the following requirements:

Requirements placed on valves of other manufacture:

Force 100 N nominal

Fully closed x > 9.0 mm

Fully open y ′14.5 mm

90187

M30 x1.5

The following makes satisfy these requirements and can be used with the SSA955:

∂Honeywell MNG

∂Cazzaniga

∂Heimeier

∂TA

∂Finimetall

∂Oventrop M30x1.5 (from 2001)

∂Junkers

Other combinations on request.

To ensure optimum control performance, the valve’s volumetric flow should not be

preadjusted.

If preadjustments are required, refer to the relevant technical documentation on the

valves for detailed information. The SSA955 supports valves with a stroke of > 0.5 mm

(refer to paragraph “Calibration”).

Siemens Radiator Control Actuator SSA955 CE1N2700en

Building Technologies 2017-11-09

The SSA955 controls the room temperature based on the data delivered by the central

apartment unit.

When using several SSA955 in one room, the first SSA955 integrated in the room

operates as the lead controller. The other SSA955 are controlled by the lead controller

via the central apartment unit. The multifunction button can be used to query the lead

controller. The multifunction LED indicates when the SSA955 operates as lead

controller.

The binding is used by the SSA955 to sign on at the central apartment unit, thus

integrating it into the RF system. The binding process is triggered via the multifunction

button. It is indicated by the multifunction LED.

Every time a binding is established and every time the batteries are changed, the

SSA955 automatically starts the calibration process. This ensures that the SSA955 will

be optimally matched to the respective radiator valve. The SSA955 informs the central

apartment unit if calibration could not be performed. If the valve’s stroke drops below

the minimum, or if no valve has been attached to the actuator, the SSA955 will deliver

an error message. If calibration was successful, the SSA955 will automatically switch to

control mode.

For use in rooms, such as sleeping rooms, where extremely quiet operation is required,

the SSA955 can be switched to low-noise operation from the central apartment unit.

Summer operation is triggered from the central apartment unit. When the SSA955

receives a command to start summer operation, the radiator valve will be opened or

closed, depending on the position demanded by the central apartment unit.

The antilime function is triggered by the central apartment unit according to a time

schedule. When the SSA955 receives an antilime command, the radiator valve will be

fully opened and fully closed once. This prevents the valve from seizing. When the

antilime function is completed, the valve will assume the previous control position

again.

The multifunction button can be used to query the battery state and the lead control

function. Both battery state and lead control function are indicated by the multifunction

LED.

The multifunction button can be used to trigger a connection test. This test is made to

check the radio link to the central apartment unit. The RF connection test is indicated

by the multifunction LED.

The multifunction button can be used to reset the SSA955 to the default state as

supplied. Then, the SSA955 must be reintegrated into the system.

If the radio transmission between SSA955 and central apartment unit is interrupted, the

built-in temperature sensor and the comfort setpoint will be used for control.

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.

2700Z11

″60 mm

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.

27 00 Z 08

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).

WARNING

Risk of explosion due to fire or short-circuit, even if the batteries are

empty

Risk of injuries from by flying parts

●Do not allow the batteries to come into contact with water.

●Do not charge the batteries.

●Do not damage or destroy the batteries.

●

Do not heat the batteries to more than 85 °C.

●If electrolyte comes into contact with eyes, immediately rinse eyes with

plenty of water. Consult a doctor.

Observe the following:

●Only replace batteries with batteries of the same type and from the

same manufacturer.

●Observe the polarities (+/-).

●The batteries must be new and free from damage.

●Do not mixed new batteries with used batteries.

●Store, transport, and dispose of the batteries in accordance with local

regulations, guidelines, and laws. Also observe information from the

battery manufacturer.

The SSA955 is protected against

overloads and blocking (slip clutch).

For service work, or in the event of fault,

the SSA955 can be driven to any

position using a 3 mm hexagonal socket

wrench.

The SSA955 cannot be repaired. It must be replaced as a complete unit.

Disposal

The device is considered an electronics device for disposal in terms of

European Directive 2012/19/EU and may not be disposed of as do-

mestic garbage.

purpose.

●Comply with all local and currently applicable laws and

regulations.

●Dispose of empty batteries in designated collection points.

Warranty

Application-related technical data are only warranted in connection with the Siemens

Synco living system. For equipment combinations, refer to the Data Sheet of the central

apartment unit.

When using the SSA955 in connection with valves of other manufacture that are

not mentioned in this Data Sheet under “Accessories”, correct functioning must

be ensured by the user. In that case, Siemens will assume no responsibility for

service and warranty.
