2 System Overview
2.2 Operating principle
The hot water and cold water circulations contain valves of the types LegioTherm K and
LegioTherm 2T . The latter serves hydraulic alignment (circulation system).
Both circulations can be rinsed . The rinse water runs into a drain.
The LegioTherm valves are equipped with a temperature sensor.
All valves are connected with the master via power supply and communication cables serially
(i.e. not radial!), which also supplies them with power. The master controls the opening angle
of the valves according to its programming, taking into account the connected sensors and cre-
ates log data in the form of protocols.
After the valves are installed according to their operating instructions, they only must be con-
nected to Hycleen Automation power supply and communication cables . The power supplied
by the master via these connection cables. For cable lengths of more than 300 m and
additional
Hycleen Automation Powerbox is required. Via its 2 cable connections, a master
with 2 power boxes can supply and control up to 1,000 m cable length.
