Field strength (reception quality)
The field strength indicates how strong
the mobile network availability is in the
current location and at the current time,
in other words how good the reception is.
The weaker the field strength, the more
likely it is that the connection will fail and
that the transmission quality will be
poor.
Continuous operation of the
Vitocom 100 is only possible if field
strength indicator "2" illuminates green
(100 % reception quality).
Heating circuit
A heating circuit is a sealed unvented
circuit between the boiler and radiators,
in which the heating water circulates.
A heating system may comprise several
heating circuits. For example, one heat-
ing circuit for the rooms occupied by you
and one heating circuit for the rooms of
a separate apartment.
