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
attached to the housing with the enclosed strain relief and
the corresponding screws.
The controller is equipped with 1 relay to which
loads
such
as pumps, valves etc. can be connected:
• Relay 1
18 = conductor R1
17 = neutral conductor N
13 = ground clamp
The
temperature sensors
(S1 to S4) have to be con-
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
®
for
data transfer with and energy supply to external modules.
The connection is carried out at the two terminals 9 and
10 marked “VBus
®
“ (either polarity). One or more RESOL
VBus
®
modules can be connected via this data bus:
• RESOL calorimeter
• RESOL large display / Smart Display
• RESOL datalogger
Electrostatic discharge can cause damage of electronic
components!

Note:
The relay is a semiconductor relay for pump speed control.
The minimum pump speed must be set to 100% when au-
xiliary relays or valves are connected.
