Electrical connection

Note
Connecting the device to the power supply
must always be the last step of the instal-
lation!
The device is equipped with 4 semiconductor relays
and 1 potential-free relay to which loads such as
pumps, valves, etc. can be connected:
Depending on the product version, the mains cable and
the sensor cables are already connected to the device.
If that is not the case, please proceed as follows:
Connect the temperature sensors (S1 to S6) to
the corresponding terminals with either polarity:
1/2 sensor 1
3/4 sensor 2
5/6 sensor 3
7/8 sensor 4
9/10 sensor 5
11/12 sensor 6
Connect the RESOL VBus to the terminals marked
®
"VBus" with either polarity:
13/14 VBus terminals
Potential-free relay:
15 conductor R5-A (normally open contact)
16 conductor R5-M (normally closed contact)
17 ... 21 ground conductor
Semiconductor relays:
22 neutral conductor R4
23 normally open contact R4
24 neutral conductor R3
25 normally open contact R3
26 neutral conductor R2
27 normally open contact R2
28 neutral conductor R1
29 normally open contact R1
17 ... 21 ground conductor
Connect the mains cable to the following terminals:
30 neutral conductor N
31 conductor L
17 ... 21
ground conductor
Attach flexible cables to the housing with the en-
closed strain relief and the corresponding screws.
The device is supplied with power via the mains cable.
The mains voltage must be 100 ... 240 V~ (50 ... 60 Hz).

Data communication / Bus

The device is equipped with a RESOL VBus
data communication with the controller. Carry out
the connection at the two terminals marked "VBus"
(any polarity).
