Description
• Master / Slave function :
The "Master" unit.s temperature and humidity probes must be
located in an "intermediate" position inside the controlled envi-
ronment. The "Master" unit drives the logic which is adopted by
all connected units. This is important to avoid situations in which
units in dehumidication and units in humidication contra-work
at the same time in the same environment.
The "Master" unitmodies the working logic in case that the
measured temperature or humidity are exceeding the setpoint
-even by just a few decimal points. In case of a black-out or of
a disconnection of the "Master" unit from the pLAN network, the
connected units will start to function independently based just
on the their own probes.
