Installation manual

COMBINING WITH OTHER FUNCTIONS
The Temperature control function devices can share the same BUS cable as other
My Home automation and emergency management applications (grey cable). If
there is already a stable cable with the automation or power management BUS
the Temperature control items can be added at any point in the system, after
installing a box item 503E for the control unit item 3550, one or more boxes
positioned at a height of 1.5 m for each temperature sensor and a unit with
enough room for the DIN actuators.
The above is also valid if the pre-existing My Home system has several
Automation systems connected using interfaces item F422 confi gured in the
“logic expansion” mode.
For systems with “logic expansion” there is no installation limitation for the
Temperature control devices, which can be installed at any point in the system.
Thus, for correct system sizing, one only need check the length of the connections
made with the BUS cable and the total device absorptions as specifi ed in
this document. For systems which also have the burglar alarm function, the
Temperature control must not be installed on the same bus as the burglar alarm,
but there must be an F422 interface between the two buses.
