2.2.1
Overview of electrical connections
The controller is equipped with two relays to which loads
can be connected:
• Relays R1 and R2 are electromechanical relays:
R1 and 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 connected 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:

Connecting the device to the power supply must always be
the last step of the installation!
The power supply of the device must be 220 ... 240 V~
(50 ... 60 Hz).
2.2.2 Data communication / Bus
The controller is equipped with the RESOL VBus
®
for data
transfer with and energy supply to external modules. The
connection 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
