4 1. Intended Use The valve drive serves for adjusting valves on radiators. It receives commands via radio signal from the pertain- ing control unit, either alone or together with other valve drives. The valve drive converts these commands in the corresponding settings on the valve. The radio controlled radiator thermostat system serves for controlling the temperature in individual rooms. Regulation of the heat transmitted by the radiator takes place by reducing the flow of the heating water. The valve drive may not be used for any other purposes than the ones stated in this operating manual. Operation is only possible with the pertaining control unit (all information relating to the overall system are contained in the operating manual of the complete system). 2. Installation and Commissioning Remove the old mechanical thermostat. In case of tight screws, use a pair of plumber s pliers. Remove the battery compartment lid of the valve drive by sliding it downwards. Insert the batteries in the battery compartment of the valve drive. Attention! Please make sure you observe the correct polarity, otherwise the electronics might be destroyed. 4

The display shows C1 and afterwards a double-digit figure, then C2 and another doubledigit figure (these two figures are the currently stored 2-digit security code of the valve drive).

5 The display shows C1 and afterwards a double-digit figure, then C2 and another doubledigit figure (these two figures are the currently stored 2-digit security code of the valve drive). Then a signal tone sounds and the display A1 appears. Now the valve drive retracts the control pin all the way to ease installation. The display now shows A2. Screw the valve drive tightly onto the valve manually by turning the cap nut (1). In case of Danfoss valves, you have to put on one of the supplied adaptors first (see the operating manual for the complete system). Briefly push the button on the valve drive once (2). The display shows A3 and the valve drive closes the valve. Afterwards the antenna symbol blinks on the display and the display shows 0%. Now transmit the security code according to the instructions in the chapter Transmitting the Security Code. If necessary, set the number of radiators as described in chapter no H in the operating manual for the complete system. Notice: Valve drives that are part of a set were already synchronized with the control unit in the factory (security code)! 5

6 3. Transmitting the Security Code Proceed as follows to transmit the security code: Press the button on the valve drive to be synchronized for more than 3 seconds. A signal sounds, the display shows AC and the antenna symbol blinks. Now the control unit has to transmit the security code. Refer to the operating manual for the control unit. The valve drive acknowledges the correct receipt of the code with a tone sequence. The display shows 0% and the antenna symbol blinks. The first radio signal received is acknowledged with a signal tone and the antenna symbol s permanently active. Replace the battery compartment lid. 4. Valve Emergency Operation If an error occurs that cannot be eliminated (because the batteries of the heating control or valve operating mechanism are low and no new batteries are at hand, for example) it may be necessary to operate the valve manually. To do so, proceed as follows: 6

Remove both batteries from the valve operating mechanism. Remove the control pin by pressing on the position marked with a (1). Place the control pin onto the peg marked with a (2).

7 Remove both batteries from the valve operating mechanism. Remove the control pin by pressing on the position marked with a (1). Place the control pin onto the peg marked with a (2). Turn the control pin: - Clockwise = increase heat - Anti clockwise = reduce heat 5. Replacing the batteries The battery symbol appears when the valve operating mechanism s batteries are low. In addition, an acoustic signal is generated every 2 minutes for one hour, three times a day. To replace the batteries, proceed as follows: Remove the battery compartment cover from the valve operating mechanism by sliding it down. Remove the old batteries and dispose of them according to the applicable environmental regulations. Wait until all the segments of the valve operating mechanism s LCD have gone out. You can speed up this process by keeping the button on the valve operating mechanism pressed. Insert two new AA batteries into the valve operating mechanism s battery compartment, making sure that the polarity is correct. Otherwise you may destroy the valve operating mechanism s electronic components! 7

8 The display shows C1 followed by a 2-digit number. The display then shows C2, followed by another 2-digit number (both numbers are the currently stored security code of the valve operating mechanism). A signal tone is then generated and A1 is displayed. The valve operating mechanism now fully retracts the control pin. A2 is then displayed. Briefly press the button on the valve operating mechanism. A3 is displayed and the valve operating mechanism closes the valve completely. The antenna symbol then blinks and 0% is displayed. The first radio signal that is received is acknowledged by a signal tone, and the antenna symbol is permanently displayed. Replace the battery compartment cover. 6.Technical Data Range (free area):... up to 100m Receiving frequency: MHz Power supply:... 2 LR6 (Mignon/AA) (if possible use alkaline batteries) Battery service life:...approx. 2 years (depending on the number of valve movements) 8

9 7. Troubleshooting Problem Permanent signal tone and F1 is displayed on the valve operating mechanism Permanent signal tone and F2 is displayed on the valve operating mechanism Permanent signal tone and F3 is displayed on the valve operating mechanism No radio symbol displayed on the valve operating mechanism. The valve operating mechanism generates a tone sequence every hour. The valve is 30% opened. Low battery symbol is displayed. The valve operating mechanism generates a tone sequence every 2 minutes for one hour. LOC is displayed when a button is pressed Possible cause The valve is too tight or the valve operating mechanism is blocked Control range is too large Valve operating mechanism is not mounted to the heat ventilator Control range is too small Radio connection failure due to interference Heating control s batteries are low Heating control s code is not right (or has been misadjusted) The valve operating mechanism s batteries are almost empty Button lock is activated Solution Remove the valve operating mechanism Manually check valve operation Mount the valve operating mechanism again If necessary, consult a heating technician Mount the valve operating mechanism again Unsuitable valve Insert a spacer that is 1mm thick (a washer, for example) between the heat ventilator and the actuator Mount the valve operating mechanism again Unsuitable valve Install the heating control in a different location Replace the heating control s batteries Transmit the current security code to the valve operating mechanism Replace the batteries Deactivate the button lock The window symbol blinks Radio connection failure to a door/window contact sensor Empty batteries Identify and rectify the fault Replace the batteries 9

10 8. Disposal a) General Dispose of the unusable product according to valid legal regulations You, as ultimate consumer, are required by law (battery regulations) to return all used batteries. Disposing of used batteries with domestic waste is prohibited! Batteries / accumulators containing toxins are marked by appropriate symbols which refer to the prohibition of disposal with domestic waste. The designations for the decisive heavy metals designation can be found on the battery under the dustbin symbol illustrated on the left). You may return used batteries/accumulators free of charge to collecting stations, our outlets or anywhere else where batteries/accumulators are sold. By doing so, you fulfil the legal requirements and contribute to the conservation of our environment. 10 exclusively to the authorities and does not warrant any properties.
