JBus protocol
Advantages
Improved corrosion resistance, recommended for
industrial, rural and marine environments
Improved corrosion resistance, recommended for
moderate marine and urban environments
Covers specific applications such as ice storage and
industrial processes
Covers specific applications such as ice storage and
industrial processes
Facilitates connections to the discharge ducts
Protects the inside of the electrical box from dusts and
sand. In general this option is recommended for
installations in polluted environments
Grant safe operation in typical "tropical" climate. This
option is recommended for all applications where
humidy inside the electrical box can reach 80% at 40°C
and unit can remain in stand-by for a long time under
this conditions.
Improves aesthetics, protection against intrusion to the
unit interior, coil and piping protection against impacts.
Improves aesthetics, coil and piping protection against
impacts.
Stable unit operation for air temperature down to -20°C
Evaporator frost protection down to -20°C outside
temperature
Evaporator and hydronic module frost protection down
to -20°C outside temperature
