• Optional: external temperature sensor, connectable (accessories)

Information for electrically skilled persons

Mounting and electrical connection

DANGER!

• Electric shock when live parts are touched.
• Electric shocks can be fatal.
• Cover up live parts in the installation environment.

Mounting notes

• Do not use controllers in multiple combinations with electrical devices. Their heat de-velopment will influence the temperature measurement of the controller.
• Do not mount controllers near sources of interference, such as electric cookers, refri-gerators, draughts or direct sunlight. This would influence the temperature measure-ment of the controller.
• When routing input cables parallel to mains cables: minimum distance of 10 cm. Oth-erwise there might be EMC interference.
• Observe the routing conditions for SELV.
• Recommendation: Use a deep appliance box.
• The optimum installation height is approx. 1.5 m.

Mounting and connecting the device

• Separate the connection terminal insert (1) and the electronics cover (3) (see figure 1).

• Connect the bus line to the device connection terminal (9) in the connection terminal insert (see figure 2).

• Binary inputs E1…E4: Connect the NO or NC contact as switch or push-button to the connection terminals 1 and 2…5 (see figure 3) of the terminal strip (8)(see figure 2).

• Binary outputs A1…A2: Connect the LED or electronic relay to the connection terminals 1 and 2, 3 (see figure 4) of the terminal strip (8) (see figure 2).

The specification of the function as inputs/outputs depends on the ETS pro- gramming.

Optional: Route an external temperature sensor in an empty pipe and guide the sensor head out at the measurement location.
Select the installation location for the temperature sensor so that it can measure the temperature without any influence from sources of interference.

• Connect the external temperature sensor to the connection terminals 5 and 6 (see figure 4) of the terminal strip (8) (see figure 2).
  The sensor cable can be extended up to a maximum of 50 m with a twisted pair cable, e.g. J-Y(St)Y-2x2x0.8. When using the KNX bus line: use a second pair of yellow/white cores.

• Insert the connection terminal insert (1) in the flush-mounted appliance box. Observe the labelling OBEN / TOP. The bus connection (9) (see figure 2) must be at the bottom, right.

• Fit the design frame (2) on the connection terminal insert (1) (see figure 1).

• Remove the cover (4) (see figure 1).

• Insert the electronics cover in the correct position into the connection terminal insert (see figure 1).

• Fasten the electronics cover with the retaining screw (5) (see figure 1).

• Reattach the cover (4) (see figure 1).

Dismantling the device

Do not damage the cover (4) and design frame (2).

• Insert the screwdriver in the slot on the bottom (see figure 5) and raise the cover (4) carefully.
• Undo the screw (5).
• Pull the electronics cover (3) off the insert.
  If subsequently mounted, the cover must be placed on the correct insert again. Pay attention to the correct labelling of the insert and cover already during the disassembly. Label them accordingly now if necessary.

Commissioning

Loading the address and the application software

• Remove the cover (4) (see figure 5).

• Press the programming button (7) (see figure 1).
  The programming LED (6) is illuminated (see figure 1).

• Assign a physical address.
  The programming LED (6) goes out (see figure 1).

• Note down the physical address on the connection terminal insert and on the back of the electronics cover.
  Observe the correct assignment of inserts and covers during the assembly.

• Reattach the cover (4) (see figure 1).
