FlowSol®E
The RESOL FlowSol®E has been especially designed for using excess power
produced by a photovoltaic system.
The measuring device reliably detects excess current and the integrated controller
redirects it to a steplessly variable electric heater for heating a water store.
Thus, excess power can be stored as regenerative heat, internal consumption can
be increased while decreasing conventional heating costs.

ÎDetermine the mounting site of the station.
ÎDrill 2 holes (10 mm diameter, 407 mm centres) one below the other and
insert wall plugs.
ÎTighten the upper screw and washer, leaving the heat protruding (1 cm).
ÎHang the station from the fastening point, adjust with a level and attach with
the 2nd screw and washer.
ÎTighten both screws equally.
ÎConnect the pipework between the station and the store.
Note
All connections are already tightened such that they usually do not have
to be tightened again. However, during commissioning of the system all
connections have to be checked for leaks (pressure test).
2.2 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
surface such as a radiator or tap!
Note
Connecting the device to the power supply must always be the last step
of the installation!
Note
It must be possible to disconnect the device from the mains at any time.
ÎInstall the mains plug such that it is accessible at any time.
ÎIf this is not possible, install a switch that can be accessed.
Do not use the device if it is visibly damaged!
This station is already pre-assembled and pre-connected.
ÎConnect the mains cables and establish the bus connection to the controller.
Note
For more information about the electrical connection, see controller
manual.
The station is supplied with power via a mains cable.The mains connection must
be carried out by means of the plug (delivered with the station) and a separate
2.5 mm² line.The power supply must be 220… 240 V~ (50…60 Hz).

ÎPut the cover on the plug.
The cover also serves as a strain relief.
ÎConnect the plug to the connector attached to the base plate.
Further loads such as washing machines must not be connected in paralel to the
station.

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 mm2and the cable can be extended up to 50 m
in the case of a single connection.

3 Commissioning
When the hydraulic system is lled and ready for operation, connect the power
unit to the mains.The controller has to be connected to the power unit (pre-con-
nected) and to the measuring unit by means of theVBus®.
ATTENTION! Damage by overheating!
Commissioning the station in a system ready for operation
which is not hydraulically lled can lead to damage caused by
overheating!
ÎBefore commissioning, ll the system with water and vent it.
ÎCheck the station for leaks and seal, if necessary.
ÎFill the heating water system (HW) with ltered (and treated) water only and
vent the system completely.
3.1 Ball valve positions
WARNING! Scald danger! Damage by overpressure!
When the ball valve is closed, too high pressure may occur in
the blocked-off line if it is heated.
ÎIn order to prevent scald danger and damage by
overpressure, make sure the blocked-off line is not
heated.

3.2 Venting the FlowSol®E
ÎFill the system with water.
ÎPut the ball valve in the ow line to the service po-
sition (see gure).
ÎSwitch-on the circulating pump at 10% speed for
1 min.
ÎPut the ball valve in the ow into the operating po-
sition.

4 Non-return valve
The non-return valve is located above the pump in the return line.
5 Maintenance
In order to remove limescale, we recommend cleaning the heating element and the
throttle orice annually.
ATTENTION! Damage caused by improper cleaning uids!
Using cleaning uids not suited for high-grade steel, copper or
nickel can damage the heating element!
ÎUse cleaning uids according to the manufacturer’s
instructions only.
For the cleaning uid, use chloride-free or low-chloride water
with low hardness.
Cleaning the heating element
In order to clean the heating element, carry out the following steps:
ÎRemove the heating element.
ÎFlush the heating element with appropriate cleaning uid against the normal
ow direction.
ÎFlush the cleaned heating element and the system with clear water.
Cleaning the throttle orice
ÎIn order to clean the throttle orice, close both ball valves.
A B
ÎRemove the lateral cover (A) at the ball valve in the ow and clean the throttle
orice (B).
6 Troubleshooting
If an error has occurred, it will be indicated on the controller screen.
Please pay attention to the controller manual!
