6. Electrical connection
6.1. Power supply
The electrical connection has to be registered with the
competent energy supply company.
The series-connected fuse for the primary circuit is
shown in the technical data, ensure that a fuse with
characteristics "C" or "K" is used.
The primary current for a possible electric heating im-
merser have to be set on site. The heating immerser
can be controlled by the Navigator control.
The TERRA AL Twin is equipped with two starting
current limiter.
The heat pump is operated via the navigator regula-
tion.
Depending on the system design, appropriate sen-
sors are required. See the connection diagrams.
To ensure a proper functioning of the heat pump, the
voltage in the network must lie within certain tolerance
limits, between 210 V and 250 V (if necessary, contact
your local energy supply company).
For data transmission, a shielded cable must be used. All electrical details can be derived from
the appropriate circuit diagram.
