Set-up

Checking the scope of delivery

• Check that the scope of delivery is complete.

Scope of delivery

Minimum clearances

Observing the requirements for the installation site

Communication unit

• Install the communication unit at a suitable position on the wall so that the WLAN RF connection and the RF connection to the thermostat are guaranteed.
• Install the communication unit close to a plug socket for the power supply.
• Position the communication unit in such a way that the communication unit can be connected to the boiler via an eBUS line.

Thermostat

• Choose a location for the thermostat that will allow an RF connection to be established with the communication unit.
• Position the thermostat in such a way that the room temperature can be recorded without any problems. You must observe the minimum clearances for this.

Installing the communication unit

Installing the communication unit's wall

1. Remove the wall socket from the rear of the communication unit.
2. Position the wall socket at a suitable location on the wall and take the cable duct for the eBUS line into consideration.
3. If aneBUS line is fed out from the wall, guide the eBUS line through the cable duct for the wall socket. If no eBUS line is fed out from the wall, guide the eBUS line through the underside of the communication unit.
4. Mark the drill holes.
5. Drill two holes that have a diameter of 6 mm.
6. Insert the supplied rawl plugs into the holes.

7. Use the supplied screws to secure the wall socket to the wall.
   
8. When you route the line from the underside of the wall socket to the eBUS connector, use the strain relief (3).
   The strain relief can be adjusted to fit different cable diameters (up to a maximum of 9 mm).
9. Connect the eBUS line to the terminals of the eBUS plug (2) on the wall socket
10. Plug the power supply unit bush into the mating connector (1) on the wall socket and route the cable through the strain relief (4).

Installing the thermostat

You can mount the thermostat on the wall using the wall plug (2) on the wall socket.

Installing the thermostat's wall base

Preliminary work

1. Before wall-mounting the thermostat, ensure that the radio link between the thermostat and communication unit is guaranteed (see the following section).
2. If the radio link is adversely affected by electrical devices or buildings, choose a different installation site for the thermostat.
   
   1. Remove the wall base from the rear of the thermostat.
   2. Position the wall base at a suitable location on the wall. Observe the minimum clearances.
   3. Mark the drill holes.
   4. Drill two holes that have a diameter of 6 mm.
   5. Insert the supplied wall plugs into the holes.
   6. Use the supplied screws to secure one of the two wall bases to the wall.

• If a thermostat has already been installed at the installation site and the wall breakthrough is not covered by the small wall base, use the large wall base. Otherwise, use the small wall base.

Placing the thermostat on the wall socket

1. Insert batteries into the thermostat.
2. Carefully place the thermostat on the wall socket.
3. Carefully press the thermostat into the wall socket until the latching lugs on the wall socket audibly click into place in the thermostat.
4. Check the RF connection between the thermostat and communication unit (temperature indicator on the display; see operating instructions).
5. If necessary, reduce the distance between the thermostat and communication unit.

Placing the thermostat on the product stand

1. Remove the wall socket from the rear of the thermostat.
2. Insert batteries into the thermostat.
3. Carefully place the thermostat on the product stand.

• Define the installation angle for the thermostat by placing it on the product stand at a 180° rotation.

4. Carefully press the thermostat onto the product stand until the latching lugs on the product stand audibly click into the thermostat.
5. Check the RF connection between the thermostat and communication unit (temperature indicator on the display; see operating instructions).
6. If necessary, reduce the distance between the thermostat and communication unit.

Condition: The boiler that is to be connected has a terminal "3 4 5".

• Make sure that the bridge is installed between terminals 3 and 4.
