Overview
The DeltaTherm®E is integrated in the FlowSol®E and is designed for using
excess PV current for heating a store.An electric heater with 3 power stages (elec-
tric immersion heaters) heats the water in the store. Thus, excess energy will be
stored in the form of thermal energy and made available when required.
• Increase in self-consumption of the PV system
• Environmental protection and reduction of heating costs
• Store excess PV current as regenerative thermal energy
• Optimisation of solar current feed-in
• Can be tted to all central heating and hot water systems
• One solar system for current and heat

2 System overview
The control unit consists of the controller, the power unit and the sensor module.
The sensor module measures the current ow directly at the energy meter. If the
power is high enough, the PV current can be used for electrically heating the water
in the store. By means of the power unit the controller controls the 3 power stages
in the electrothermal station for store heating.
In order to compensate for thermal losses,an internally calculated switch-on power
has to be exceeded. An additional supply reserve will prevent using power from
the mains because of system-dependent tolerances (see Status / Controller on
page 18).
The pump speed is adapted so that the target temperature at S1 is reached for store
loading in layers. If the maximum store temperature (S2) is reached, loading stops.
Optionally, different optional functions can be activated, see page 21.
Common operation with a battery is possible, but correct functioning cannot be
guaranteed in all cases. PV current is used with the following priorities:
1. Direct consumption
2. Battery loading
3. Loading of a hot water store
4. Current feed-in
For this purpose, the sensor modules and the battery have to be arranged as shown
in the illustration. The current sensor Ⓐof the battery must not measure the
current consumption of the controller and the loads controlled by the controller.
The SR off function allows remote access to the controller, e.g in order to switch
it off when the battery is in use. If the switching input S5 is closed, all loads are
switched off independently from the excess measured.

3 Installation
3.1 Mounting
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
Note
Strong electromagnetic elds can impair the function of the device.
ÎMake 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.
If the controller is not equipped with a mains connection cable and a plug, the
device must 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.
Step-by-step installation:
ATTENTION! Damage through overheating!
Commissioning the power stages in a system electrically con-
nected, but not hydraulically lled can lead to damage caused by
overheating!
ÎMake sure the hydraulic system is lled and ready for
operation.
ÎMake sure the hydraulic system is lled and ready for operation.
The controller and the power unit are integrated in the electrothermal station.
ÎMount the sensor module on a DIN rail in the domestic distribution board
as close as possible to the energy meter. Make sure that no load is installed
between the sensor module and the energy meter.
ÎConnect the current sensors and the conductors of the sensor module in
phase directly at the energy meter (see page 7).
ÎConnect the sensor module with the controller by means of the VBus®(see
page 7 and page 9).
ÎEstablish the power supply of the controller (see page 9).
ÎRun the commissioning menu (see page 16).
ÎCarry out the desired adjustment in the controller menu (see page 19).
3.2 Electrical connection
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
ATTENTION! ESD damage!
Electrostatic discharge can lead to damage to electronic com-
ponents!
ÎTake care to discharge properly before touching the
inside of the device! To do so, touch a grounded sur-
face such as a radiator or tap!
Note
The connection to the power supply must always be the last step of the
installation!
Do not use the devices if they are visibly damaged!
The power unit 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.
The controller is supplied with power via the power unit.

Data communication VBus®
The connection is to be carried out at the terminals marked VBus (either polarity).
The bus cable can be extended with a two-wire cable (bell wire).The cable carries
low voltage and must not run together in a cable conduit with cables carrying a
higher voltage than 50 V (please pay attention to the valid local regulations). The
cross section must be at least 0.5 mm2 and the cable can be extended up to 50 m in
the case of a single connection.

Digital S0 impulse outputs
S0-1: Heating

The S0 outputs can be used for transferring the heat energy of the FlowSol®E to
external energy management systems and for feeding the excess into the public grid.

Three-phase connection
ÎConnect the current sensors and the conductors of the sensor module in
phase directly at the energy meter.The arrow indicated on the current sensors
must point in the direction of the loads.
ÎMake sure that no load is installed between the energy meter and the current
sensors.
The sensor module adds up the power values of all 3 phases. All 3 phases have to
be connected to the sensor module.
