8.4.3 Outside temperature via bus
The outside temperature can only be provided via the bus if communication is
active and an outside temperature set (Outside temperature zone = "----" means
that the outside temperature on the bus is inactive).
To activate different outside temperatures to be sent via bus (e.g. outside
temperature on the northern side of the building for the air conditioning plants, and
outside temperature on the eastern side of the building for heating zone "East",
etc.), they must be assigned to specific outside temperature zones.
Refer to section 28 "Communication" for the required settings.
