Technical Data
| Supply voltage | 24 V AC/DC (22…26 V AC/DC) |
|---|---|
| Power consumption | 60 mA |
| Protection class | IP30 |
| Ambient humidity | 10…90 % RH (non-condensing) |
| Ambient temperature | 0…50 °C |
| Storage temperature | -20…+70 °C |
| Cable connection | Terminal block, push-in. Max. 1.5 mm2 (AWG 16) |
| Mounting | Room (flush-mounted with screw distance cc 60 mm) |
Installation
The room unit is installed indoors on a wall, using the mounting holes on the back plate. It is to be installed on an EU standard wall mounting box as the terminal block stands out a few millimetres from the back plate.
Note! The display is pre-configured upon delivery and can therefore be used directly together with Regin’s room controllers. When used with other controllers, the communication settings might need to be changed in the Firmware configuration menu (see Table 1).
Wiring
Depending on the used controller there are two different wiring options:
- Option 1: The room unit is connected via a EDSP-K3 cable to the controller’s display port.
- Option 2: The room unit is connected to the controller’s serial port. The supply voltage is connected to the same supply voltage as the controller (G and G0).
Note! For connecting ED-RUD to RegioArdo and RegioEedo ooppttiioonn 11 must be used.
Wiring according to option 1
Wiring according to option 2
Handling
The display consists of segments and buttons that all can be controlled individually via the Modbus master. Regardless if the display is connected to a master controller or not it is always possible to configure communication parameters in the display:
- Power up the display and press the On/Off button for 5 seconds while in Power up sequence, then press the arrow down button twice
- Navigate in the Firmware configuration menu with the arrow buttons
- Press the On/Off button to select a parameter. Use the arrows to adjust the value. Always confirm with the On/Off button.
- At the end of the menu the word EXIT appears in the display. To exit the menu press the On/Off button when in EXIT.
Note After changing parameters, make sure to have the power on at least 5 s to ensure that the values are stored correctly.
