DeltaTherm® PV
®
The DeltaTherm
PV controller detects excess current, e.g. produced by PV
systems, calculates the energy available and redirects it to an electric heater. Thus,
excess current can be directly converted into thermal energy and stored.
Single-phase eletromechanical immersion heaters up to 3 kW with an operating
voltage of 230 V~ and with a thermal cut-out can be used.
Electronically controlled immersion heaters are not suitable.

Electric shock!
Upon opening the housing, live parts are exposed!
Î Always disconnect the device from power supply
before opening the housing!
Note
Strong electromagnetic elds can impair the function of the device.
Î Make sure the device as well as the system are not exposed to strong
electromagnetic elds.
The devices must only be located in dry and dust-free interior rooms.

additionally be supplied from a double pole switch with contact gap of at least 3 mm.
Please pay attention to separate routing of sensor cables and mains cables.
In order to mount the device to the wall, carry out the following steps:
Î Unscrew the screw from the cover and remove it along with the cover from
the housing.
Î Mark the upper fastening point on the wall. Drill and fasten the enclosed wall
plug and screw leaving the head protruding.
Î Hang the housing from the upper fastening point and mark the lower fastening
points (centres 105 mm).
Î Insert lower wall plugs.
Î Fasten the housing to the wall with the lower fastening screws and tighten.
Î Carry out the electrical wiring in accordance with the terminal allocation (see
page 8).
Î Put the cover on the housing.
Î Attach with the fastening screw.

3.2 Electrical connection
WARNING!
Electric shock!
Upon opening the housing, live parts are exposed!
Î Always disconnect the device from power supply
before opening the housing!
ATTENTION!
ESD damage!
Electrostatic discharge can lead to damage to electronic components!
Î Take care to discharge properly before touching the
inside of the device! To do so, touch a grounded surface
such as a radiator or tap!
Note
Connecting the devices to the power supply must always be the last step
of the installation!
Do not use the devices if they are visibly damaged!
The controller is supplied with power via a mains cable. The power supply of the device
must be 100 … 240 V~ (50 … 60 Hz). The cross section of the cable must be 2.5 mm².
Note
Connect the immersion heater with a shielded cable with a cross sec-
tion of 3 x 2,5 mm² (see page 11).
The cable length must not exceed 5 m.

If the temperature at the store sensor S1 falls below the value [Maxtemp. - Hysteresis], the electric heater can be used for heating. If the store temperature reaches
the adjusted maximum temperature, the store will no longer be loaded in order to
avoid damage caused by overheating.
The Reserve is an adjustable excess power which will be fed into the grid and not
used for heating. The reserve can be used, e. g. in large PV systems, in order to start
the heating at a later point in time. This will reduce power peaks at noon.

The controller is equipped with a MicroSD card slot for MicroSD memory cards.
With a MicroSD card, the following functions can be carried out:
• Logging measurement and balance values. After the transfer to a computer, the
values can be opened and visualised, e. g. in a spreadsheet.
• Store adjustments and parameterisations on the MicroSD card and, if necessary,
retrieve them from there.
• Running rmware updates on the controller.
Î To safely remove the MicroSD card, always select the menu item Remove
card... before removing the card.
Î Wait until Remove card is displayed.

WARNING!
Electric shock!
Upon opening the housing, live parts are exposed!
Î Always disconnect the device from power supply
before opening the housing!
ATTENTION!
ESD damage!
Electrostatic discharge can lead to damage to electronic components!
Î Take care to discharge properly before touching the
inside of the device! To do so, touch a grounded surface
such as a radiator or tap!
Note:
The MicroSD card slot will only be accessible after the housing is opened.
In order to insert or remove the SD card, proceed as follows:
Î Disconnect the device from the power supply.
Î Unscrew the screw from the cover and remove it along with the cover from
the housing.
Î Insert the MicroSD card into the slot or remove the MicroSD card from the
slot, respectively.
Î Put the cover on the housing.
