2.1 Mounting
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the controller 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!
The unit must only be located in dry interior rooms. It is not suitable for installation
in hazardous locations and should be protected against electromagnetic fields.The
controller 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.
ÎUnscrew the crosshead screw from the cover.
ÎPull the cover downwards to remove it from the housing.
ÎMark the upper fastening point on the wall, drill and fasten the enclosed wall
plug and screw leaving the head protruding.
ÎHang the housing from the upper fastening point and mark the lower fastening
point through the hole in the terminal box (centres 130 mm). Drill and insert
the lower wall plug.
ÎFasten the housing to the wall with lower fastening screw and tighten.
ÎCarry out the electrical connections according to the specifications.

2.2 Electrical connection
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the controller 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:
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.
Note:
Connecting the device to the power supply must always be the last step
of the installation!
ÎDo not use the device if it is visibly damaged!
The power supply of the device must be 220… 240V~ (50 … 60 Hz).
The controller is equipped with two relays to which loads can be connected:
• Relays R1 / R2 are electromechanical relays:
R1 / R2 = conductor R1 … R2
N = neutral conductor N (common terminal block)
PE = protective conductor PE (common terminal block)
Depending on the product version, mains cable and sensor cables are already con-
nected to the device. If that is not the case, please proceed as follows:
Connect the temperature sensors (S1 to S4) to the corresponding terminals
with either polarity.
Connect the mains cable to the following terminals:
19 = neutral conductor N
20 = conductor L
12 = protective conductor ⏚
2.3 Data communication / Bus
The controller is equipped with the RESOL VBus®for data
transfer with and energy supply to external modules.The con-
nection is carried out at the two terminals marked “VBus”
(either polarity). One or more RESOL VBus®modules can be
connected via this data bus:
• RESOL DL2 Datalogger
• RESOL GA3 Large Display
• RESOL SD3 Smart Display
• RESOL STA-W kWh output module
• RESOL VBus®/USB Interface adapter

If the maximum pool temperature is exceeded by a certain value (DTcool), this
function cools the pool by discharging heat through the absorber.This is only pos-
sible if the absorber is cooler than the pool by the adjusted temperature difference
DTcoolon.
Cooling is switched off when the value DTcooloff is reached or when Poolmax. is
underrun.

Adjustment range: 0.3 … 10.0 K
Factory setting: 3.0 K
Experte/Adjustments/DTcooloff
Adjustment range: 0.2 … 10.0 K

8 Error indication
A possible failure of the pool-, flow- or absorber sensor will be indicated on the
display.The solar system will be switched off or, if already off, remain inactive. In the
case of a failure of the outdoor temperature sensor, the system will not be switched
off or kept inactive.

10.1 Sensors and measuring instruments
Sensors
Our product range includes high-precision platinum temperature sensors, flatscrew
sensors, outdoor temperature sensors, indoor temperature sensors, cylindrical clip-
on sensors, also as complete sensors with immersion sleeve.
Overvoltage protection device
In order to avoid overvoltage damage at collector sensors (e.g. caused by local
lightning storms), we recommend the overvoltage protection RESOL SP10.
10.2 VBus®accessories
AM1 Alarm module
The AM1 alarm module is designed to signal system failures. It is to be connected to
the VBus®of the controller and issues an optical signal via a red LED if a failure has
occurred.The AM1 also has a potential-free relay output, which can e. g. be connec-
ted to a building management system (BMS).Thus, a collective error message can be
issued in the case of a system failure.

DL2 Datalogger
This additional module enables the acquisition and storage of large amounts of data
(such as measuring and balance values of the solar system) over a long period of time.
The DL2 can be configured and read-out with a standard internet browser via its
integrated web interface. For transmission of the data stored in the internal memory
of the DL2 to a PC, an SD card can be used.
The DL2 is appropriate for all controllers with RESOL VBus®. It can be connected
directly to a PC or router for remote access and thus enables comfortable system
monitoring for yield monitoring or for diagnostics of faults.
10.3 Interface adapters
VBus®/ USB interface adapter
The new VBus®/ USB interface adapter is the interface between the controller and
a personal computer.With its standard mini-USB port it enables a fast transmission
of system data via the VBus®for processing, visualizing and archiving.A full version
of the RESOL ServiceCenter software is included.
