Engineering notes
• A transformer with an output voltage of AC 24 V+/– 15% (SELV extra low voltage) is
required for the room controller power supply.
The transformer rating must be sufficient for
− the room controller and associated 24 V electrical consumers (max. 35 VA)
− all electrical consumers connected to the 24 V relay outputs
• A line coupler from the EIB range is required after every 120 room controllers. In
practice, however, a line coupler needs to be connected after approximately 50
rooms, because the maximum cable length is 1000 m, and the cable length between
rooms is typically 20 m.
• The room controller must be installed in a control panel or covered enclosure, which
can only be opened with a key or tool.
• The relevant technical, and health and safety regulations must be observed,
including local electricity company regulations applicable to connection of devices to
the electricity network.
• The connection terminals can be orders as an HCS3.1 terminal kit (see "Ordering").
• The management level PCs must be protected with a UPS (uninterruptible power
supply).
• A mechanical safety lock must be provided to allow the door to be opened from the
outside in extreme emergencies.
