Three-state Relay & Double Sender: F&Home Radio rH-TSR1S2
Front view
The rH-TSR1S2 LR module is a combination of a tree-state relay and two contact inputs. The module sends information about the opening and closing of the contacts to the system and controls the relay, which can activate forward-reverse electric motor(s). The communication with the server takes place by radio. The module has two physical inputs for the connection of two monostable potential free contacts, as well as two relay outputs. The load can be resistive, inductive or capacitive, in both AC and DC circuits. The rH-TSR1S2 LR module is particularly suitable for controlling blinds/shutters, which requires changing the operating direction of the motor(s), or for other equipment where two circuits cannot be activated simultaneously. The range of the module is much longer (up to 300 m) than of the standard version (rH-TSR1S2 F1222).
Symbol in design and configuration software:
The symbol of rH-TSR1S2 LR
The module is represented by object that consists of two binary inputs and two binary relay outputs, separate for each physical input. The inputs of the object are used to control the relay channels, the outputs provide information about the operating status. The element also has two digital inputs and two outputs, separate for each physical input. The shorting or opening a contact changes the logic state at the corresponding output.
  • Switch off the AC line and make sure that there is no voltage.
  • Connect the wires according to the diagram above.
  • Mount the module in a suitable installation box.
  • Adjust the antenna wire parallel to one of the server antennas, as far as possible from the other wires.
  • Switch on the AC line.
  • Register the device in the system.
  • Close the installation box.
An example application:
In the diagram above, F1222 or F1223 three-state relay with dual sender is responsible for control of blinds/shutters. By pressing the momentary switches connected to the F1222 or F1223 module the user can lower/raise the blinds/shutters.
A more advanced scheme for blinds/shutters control can be found in the Alarm and shutters control project article.

F&HOME RADIO integrates electrical installations in such a way that the processes of heating, air conditioning, ventilation, lighting, alarm and access control form one efficient system - all for the safety and comfort of the residents. With wireless two-way communication between the central unit (server) and both sensors and actuators, software solutions, as well as remote control of the system that can performed by the users in many ways, the system allows them to manage home energy resources in a manner appropriate to their needs.
In practice, this means the ability to integrate electrical appliances in such a way that a hand gesture can create a romantic light scene in the living room and bedroom, pull down the shutters or blinds and adjust the interior temperature, for example. The option of remote control via the Internet ensures that even after our return from a long journey we are welcomed by the house as if we have never left.
