Smart valve actuator SSA911.01TH Wireless radiator valve actuator, works with RDS110.R ● ● ● ● ● ● ● ● A6V11739247_en--_a 2020-10-08 RF-controlled actuator communication based on THREAD protocol (2.4 GHz, bidirectional) Connection and operation with RDS110.R and optionally RCR114.1 Battery-powered by commercially available 1.5 V AA batteries Valve thread connection M30x1.5 mm Nominal stroke 2.
Use ● ● ● The SSA911.01TH wireless radiator valve actuator is designed to work on radiator valves of different manufacturers in HVAC applications using M30x1.5 thread. It operates the valve to control the water flow and controls the room temperature. The valve actuator works only in combination with Siemens Smart Thermostat RDS110.R and optionally with wireless repeater RCR114.1. One RDS110.R can be paired with up to 6 radiator valve actuators in parallel. Up to 3 wireless repeaters RCR114.
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.
Accessories Adapter AV.. for third-party valves Type (= stock no.) For radiator valves from: AV51 Beulco distributor M30x1.0 AV52 Comap AV53 Danfoss RA-N (RA2000) AV54 Danfoss RAVL AV56 Giacomini Theft protection kit Type Stock no. ATN5 S55845-Z244 The theft protection kit secures the actuator; it prevents the batteries from being removed and the actuator from being unscrewed from the radiator valve without the use of a tool. Equipment combinations Siemens valves The SSA911.
Third-party valves without adapter The SSA911.01TH can operate third-party radiator valves without adapter, provided they have a M30x1.5 mm connecting thread and meet the following requirements: Force 90 N nominal Fully closed x > 9.0 mm Fully open y ≤ 14.5 mm Valves of the following manufacturers may be used with the SSA911.01TH: ● ● ● ● Honeywell MNG Cazzania Heimeier TA ● ● ● ● Finimetall Oventop M30x1.
Notes Security CAUTION National safety regulations Failure to comply with national safety regulations may result in personal injury and property damage. ● Observe national provisions and comply with the appropriate safety regulations. WARNING Burns from hot surface The screw nut with which the actuator is fastened on the radiator valve will become hot. Risk of burns from contact with the screw nut. When servicing the actuator: ● ● Switch off the radiator. Allow the radiator to cool off.
Mounting The SSA911.01TH is mounted on the radiator valve. There are no preferred mounting positions; the actuator SSA911.01TH may be operated in all mounting positions. Make sure the display is visible and the button is accessible. WARNING Falling objects Overhead installation may result in injury from falling objects. ● Do not install the actuator more than 2 m above ground. Firmly tighten the screw nut by hand. No tools are required to tighten the actuator on the valve.
Operation HMI The interface consists of an LCD display [1] and one push button [2]. During normal operation, the display is switched off in order to conserve energy and ensure a long battery life.
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.
Maintenance The SSA911.01TH is maintenance free. The actuator and the Smart Thermostat will indicate when replacing the batteries is required approximately 2 months before the batteries are completely empty and the actuator switches off. Replacing the batteries To replace the batteries, the SSA911.01TH should remain mounted on the radiator valve and the Smart Thermostat should remain on power and switched on. Replacing the batteries does not require any tools.
