5. ELECTRICAL ACCESORIES
5.1 ELECTRIC BOX CBL10
Self-extinguishing plastic box (class V0), which contains a 12 pole terminal board and a voltage transformer (230/24 V~ 10 VA),
for the electrical connection of the modulating valves. It is supplied as standard when the regulators CER10/B e CER30/B are
requested.
5.2 ELECTRIC BOX CBL20
Self-extinguishing plastic box (class V0), which contains a 12 pole terminal board and a power relay card (230 V~):
this card is requested either when an electric heater is mounted on the fancoil unit or to control the fan speeds in Master/
Slave configuration. It can be combined with the following regulators: CMR00, CER00 and CER20.
5.3 ELECTRIC BOX CBL30
Self-extinguishing plastic box (class V0), which contains a 12 pole terminal board, a voltage transformer (230/24 V~ 10 VA)
for the electrical connection of the modulating valves and/or 24 V~ controls, a power relay card (24 V~), which is requested
to control the fan speeds in Master/Slave configuration.
It can be combined with the following regulators: CER11, CER31, CER00 and CER20 (with power supply 24 V).
