4.3 Allocation of a room control unit to a heating zone
(pairing)
1. Press the rmBUS button of the base station for three seconds in
order to start the pairing mode.
- The LED “Heating zone1” flashes.
2. Select the desired heating zone by pressing again briefly.
- For three minutes, the selected heating zone is ready to receive
the pairing signal of a room control unit.
3. Activate the pairing function at the room control unit (see Room
Control Unit Manual).
- The pairing mode ends automatically after establishing a
successful connection.
- The LED of the heating zone previously selected will light up for
1 minute.
4. Repeat the process for allocating more room control units.
One room control unit can be allocated to various heating
zones. The allocation of several room control units to one zone
is not possible.
4.4 Activate test for wireless operation
The test for wireless operation checks the communication between
the base station and the room control unit. The wireless test must
always be carried out with the room control unit being at its intended
final location.
The base station must not be in pairing mode during the testing for
the wireless operation.
1. Start the wireless test at the room control unit (see Room Control
Unit Manual).
- The heating zone allocated to the room control unit is activated
for one minute and is switched o or on depending on its
current operating status.
2. If there is no activation, the signal reception is insucient.
Proceed as follows:
- Taking into account the installation conditions of the room
control unit, change its installation position until you have a
signal reception, or
- Use the optional accessories “Active antenna” or “Repeater” in
order to amplify the wireless signal. You can find information on
the installation in the respective manual.
