2.2 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 compo-
nents!
Î
Take 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.
Î
Install the mains plug such that it is accessible at any time.
Î
If 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

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.

Connect the
temperature sensors
(S1 to S3) to the corresponding terminals
with either polarity:
1 / 2 = Sensor 1 (e. g. collector sensor)
3 / 4 = Sensor 2 (e. g. store sensor)
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).
