The power supply to the controller must be carried
out via an external power switch (last step!) and the
supply voltage must be 220 ... 240 V~ (50 ... 60 Hz).
The controller is equipped with 1 relay to which the pump
can be connected:
•
Relay 1
14 = conductor R1
15 = neutral conductor N
13 = ground terminal
• The
digital sensors are connected to the input Digital
Sensor.
• The
RESOL VBus
®
is connected to the terminals mar-
ked "VBus"
• The terminals marked "
PWM" are control outputs for a
high-efficiency pump
• The
temperature sensors (S1 to S3) have to be con-
nected with any polarity to the following terminals:
S1 = sensor 1 (sensor collector )
S2 = sensor 2 (sensor store base)
S3 = sensor 3 (sensor store top)
• The mains connection is at the terminals:
16 = neutral conductor N
17 = conductor L
11 = ground terminal
Important note:
The mains connection must be carried out with the com-
mon ground of the building to which the pipework of the
solar thermal system is connected.

WARNING!
Always disconnect the controller
from power supply before opening
the housing!
Note:
If no indication is made on the display, the fuse
is blown. Replace the fuse with a glass fuse 4,0 A.
For this purpose, remove the fuse bracket from
the base.
