The controller is equipped with the RESOL VBus
®
for data
transfer with and energy supply to external modules. Carry
out the connection at the two terminals marked “VBus” (any
polarity). One or more RESOL VBus
®
modules can be con-
nected via this data bus, such as:
• RESOL GA3 Large Display from version 1.21
• RESOL SD3 Smart Display from version 1.21
• RESOL DL2 Datalogger
• RESOL VBus

Connecting the device to the power supply must always be
the last step of the installation!
The controller is supplied with power via a power supply
line. The power supply of the device must be 100 ... 240 V~
(50 ... 60 Hz) .
The controller is equipped with a change-over relay to which
a
load
such as a pump, a valve, etc. can be connected:
10 = ground terminal
11 = ground terminal
12 = conductor R1-R (normally closed contact)
13 = conductor R1-A (normally open contact)
14 = neutral conductor N
Depending on the product version, power supply cable and
sensor cables are already connected to the device. If that is
not the case, please proceed as follows:
Connect the
temperature sensors
(S1 to S3) to the
corres ponding terminals with either polarity:
1/2 = Sensor 1 (e. g. sensor collector)
3/4 = Sensor 2 (e. g. sensor tank)
5/6 = Sensor 3 (e. g. sensor tank top)
Connect the RESOL VBus
®
to the terminals marked
“VBus” with either polarity:
7 = VBus terminal
8 = VBus terminal
Connect the
power supply cable
to the following ter-
minals:
15 = neutral conductor N
16 = conductor L
9 = ground terminal
Attach flexible cables to the housing with the enclosed
strain relief and the corresponding screws.

Electrostatic discharge can cause dam-
age of electronic components!
