The power supply to the controller must be carried out via
an external power switch (last step!) and the supply voltage
must be 100 ... 240 V~ (50 ... 60 Hz). Flexible cables must be
fuse
attached to the housing with the enclosed strain relief and
the corresponding screws.

The controller is equipped with 1 relay to which loads such
IP 20
50-60 Hz
as pumps, valves etc. can be connected:
• Relay 1
load terminals
The temperature sensors (S1 to S4) have to be con-
mains terminals nected to the following terminals (either polarity):
1 / 2 = sensor 1 (e. g. sensor collector 1)
3 / 4 = sensor 2 (e. g. sensor store 1)
5 / 6 = Sensor 3 (temperature sensor S3)
7 / 8 = sensor 4 (e. g. sensor store TRF)
The mains connection is at the terminals:
19 = neutral conductor N
20 = conductor L
12 = ground clamp
The controller is equipped with the RESOL VBus
data transfer with and energy supply to external modules.
The connection is carried out at the two terminals 9 and
10 marked "VBus
