Communication | To provide this function, connection of the RVL469 to ist partner unit via the data bus is |
| mandatory. Each RVL469 requires one partner unit. |
| Communication with other units also takes place via the data bus and facilitates: |
| – Signalling of heat demand to the heat source |
| – Exchange of locking and enforced signals |
| – Exchange of measured values such as outside temperature, return temperature, flow |
| temperature and of clock signals |
| – Communication with other devices |
| – Reception of heat demand signals from the SYNERGYR OZW30 central unit (from |
| software version 3.0) |
| – Exchange of error messages |
Fault messages and flow temperature alarm
–Fault message in the event of sensor faults
–Fault message in the event of data bus faults
–Flow temperature alarm; adjustable is a period of time during which the flow temp- perature may stay outside the set limits; a fault message is given when the time has elapsed
Other functions | – Display of parameters, actual values, operational statuses and fault messages |
| – Simulation of outside temperature |
| – Relay test; all relays can be controlled manually |
| – Sensor test; all measured values of the sensors can be displayed |
| – Testing the contacts connected to terminals |
| – Outside |
| perature is maintained, its setpoint and the response threshold can be adjusted |
| – Pump overrun time to prevent buildup of heat |
| – Periodic pump run (pump kick) to prevent seizing of the pump in the summer |
| – Controller hours run meter |

Mechanical design |
|
The RVL469 is comprised of controller insert, which accommodates the electronics, the | |
| power section, the output relays and - on the front - all operating elements, and the |
| base, which carries the connection terminals. The operating elements are located be- |
| hind a lockable transparent cover. |
| The operating instructions can be inserted in the transparent cover. |
| The controller insert is secured to the base with two screws, one of which can be |
| sealed. The cover can also be sealed. |
| The RVL469 can be fitted in three different ways: |
| – Wall mounting (on a wall, in the control panel, etc.) |
| – Rail mounting (on a standard DIN mounting rail) |
| – Flush panel mounting (control panel door, etc.) |
Analog operating | – Buttons for selecting the required operating mode |
elements | – Info button |
| – Direct adjustment of the heating curve with the the little bar on the front of the unit |
| (only if analog setting is selected) |
| – Knob for manual readjustment of the room temperature |
| – Three buttons for manual operation and manual positioning commands |
Digital operating | The entry or readjustment of all setting parameters, activation of optional functions and |
elements | reading of actual values and statuses is made according to the operating line principle. |
| An operating line with an associated number is assigned to each parameter, each actual |
| value and each function that can be selected. |
| One pair of buttons is used to select an operating line and one pair to readjust the dis- |
| play. |
