3 Function
The Altech V3 IP room control unit Display ALEC-42090D allows to set the room
temperature in a time-controlled way in order to adapt the heating phases to your
individual requirements. The room control unit measures the temperature and
transmits these data cyclically to the Altech V3 IP Base station ALEC-42010-xx or to
connected Altech V3 IP radiator thermostats. The registered values allow an exact
regulation of the room temperature. The target temperature can be set manually
with the setting wheel.
The range within buildings can differ strongly from the range outside (in
open air).
Communication with other components will be performed over the Homematic
(HmIP) radio protocol. The radio transmission is done on a non-exclusive transmis-
sion path; thus, disturbance cannot be completely excluded. Disturbance impacts
can be caused by switching processes, electric motors or electric appliances.
