DeltaSol®BS/2 HE solar controller
The controller for standard solar thermal systems.
The DeltaSol®BS/2 HE controller provides a clear operating concept and is
equipped with the combined display with system-monitoring. Flashing symbols for
sensors and pumps enable an immediate allocation of temperatures, temperature
differences and active actuators.Thus, adjusting and monitoring the solar system is
quick and easy.

The unit must only be located in dry interior rooms.
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.
In order to mount the device to the wall, carry out the following steps:
ÎUnscrew the crosshead screw from the cover and remove it along with the
cover 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 (centres 130 mm).
ÎInsert lower wall plug.
ÎFasten the housing to the wall with the lower fastening screw and tighten.
ÎCarry out the electrical wiring in accordance with the terminal allocation (see
page 6).
ÎPut the cover on the housing.
ÎAttach with the fastening screw.

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 compo-
nents!
ÎTake care to discharge properly before touching the in-
side of the device!
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!

The controller is equipped with 1 semiconductor relay to which a load such as a
pump, a valve, etc. can be connected:
• Relay 1
18 = Conductor R1
17 = Neutral conductor N
13 = Grounding terminal
The mains connection is at the following terminals:
19 = Neutral conductor N
20 = Conductor L
12 = Grounding terminal
The terminals marked PWMARECONTROLOUTPUTSFORAHIGHEFlCIENCYPUMP
7 = PWM -
8 = PWM +
Speed control of a HE pump is possible via a PWM signal.The pump has to be con-
nected to the relay as well as to the PWM output of the controller. Power supply
to the HE pump is effected by switching the relay on or off.

5 / 6 = Sensor 3 (e. g. store sensor top)
2.3 Data communication / Bus
The controller is equipped with the VBus®for data transfer and energy supply
to external modules.The connection is to be carried out at the terminals marked
VBus (any polarity).
One or more VBus®modules can be connected via this data bus, such as:
• DL2 Datalogger
• DL3 Datalogger
Furthermore, the controller can be connected to a PC or integrated into a network
via the VBus®/USB or VBus®/LAN interface adapter (not included).

2.4 System: Standard solar system with 1 store
The controller calculates the temperature difference between collector sensor S1
and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference (DT O), the solar pump will be activated by the
relay, and the store will be loaded until the switch-off temperature difference (DTF)
or the maximum store temperature (S MX) is reached.
Sensor S3 can optionally be connected for measurement purposes.
If heat quantity measurement (OHQM) is activated, S3 is to be used as the return
sensor.
