0-10V signal of connected output
The connected output of the
electric flow heater can be
obtained as a 0-10Vdc signal,
which corresponds to 0-100%
of
the installed output.
Outdoor temperature sensor and alternative
heating, option
See "User level" rows 7, 8 and 9 and "Advanced
service level" rows 6, 7 and 15.
The outdoor temperature sensor is
fitted to an outside wall, at half
the height of the façade, close
to a corner, facing north / north
west. The sensor must not
be placed where it will be
exposed to the morning sun or
close to valves, windows or doors.
The sensor is connected in clamps 1-2, with at least 0.4 mm
2
cable up to 30 meters.
The temperature can be changed with an external potential-
free contact function; alternative temperature.
Connection to clamps 3-4.

Current Transformers - Load Guard
See "Service level" rows 3 and 4!
The current transformers need not
be connected if the function is not to be
used. The guard is not phase-sensitive.
The current transformers are placed
on the wires from the fuses, which
must be protected. Connection
must be made with a high-
voltage insulated cable, with a
minimum area of 0.75 mm

. A joint
conductor is connected in terminal 4.

Electrical installation
Electrical installation shall be carried out in accordance
with the applicable regulations, by an authorized
electrical installer or by someone who is covered
by the company's self-inspection programme!
The electric flow heater and heating system must
be filled with water and vented before the flow heater
is connected to the power supply.
Low-voltage cables may not be laid parallel to high-
voltage cables.
Cables and pipes must be laid so that it is possible
to remove the front plate and open the top plate.
Do not drill into the electric flow heater's cover
plates. Cuttings can damage the electric flow
heater's electrical equipment!

Output limitation / Output control, 0-10V
See "Advanced service level" row 13 and "Service
level"l row 5!
Controlled by an external
voltage signal, 0-10Vdc.
The control signal controls
the output stages
0-100% of installed output.
Installed output is the number of
stages the electric flow heater is allowed to use.
The existing jumpers 3-4 are removed.
The control signal is connected to terminals 4-5.
