Electrical connection
Power supply
With the monobloc system, the mains connection is provided directly on the
monobloc unit. With the bi-bloc system the mains connection is provided on
the
hydromodule, whereby the power supply of the outdoor unit is provided
via an additional connection between the hydromodule and outdoor unit.
An overview of the above-mentioned differences is depicted in the following
table. The required cross-sections can be derived from the technical data.
