The second or third attempt at calibration occurs automatically after an 8-

minute delay.

After three failed calibration attempts the actuator stem remains in the

extended position and the radiator valves are closed.

For valves with strokes < 1.5 mm, the actuator/valve combination locks after

three failed calibration attempts.

The new Siemens type VDN.., VEN.. and VUN.. radiator valves have in all

1.5 mm stroke.

A 3 mm hexagonal socket wrench can be used to move the actuator to any position.

However, if a control signal from the controller is present, then this takes priority in

determining the position.

To retain the manually set position, unplug the connecting cable or switch off the

operating voltage and the control signal.

The actuators are maintenance-free.

When carrying out service work on the plant, following must be noted:

· Turn power off (e.g. remove the plug)

· If necessary, disconnect electrical connections from the terminals

· The actuator must be commissioned only with a correctly mounted valve in place!

SSA.. actuators cannot be repaired; the complete unit must be replaced.

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

domestic garbage.

● Dispose of the device through channels provided for this

purpose.

● Comply with all local and currently applicable laws and

regulations.

Warranty

The technical data given for these applications is valid only when the actuators are

used with the Siemens valves listed under "Equipment combinations", page 2.

The use of the SSA.. actuators in conjunction with third-party valves invalidates

any warranty offered by Siemens Building Technologies / HVAC Products.
