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 2 relays to which loads
such as pumps, valves etc. can be connected:
• relay 1
18 = conductor R1
17 = neutral conductor N
13 = gound clamp
• relay 2
16 = conductor R2
15 = neutral conductor N
14 = ground clamp
Temperature sensors (S1 to S4) have to be connected
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 (sensor S3)
7 / 8 = Sensor 4 (e. g. sensor TRF)
The mains connection is at the terminals:
19 = neutral conductor N
20 = phase 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 ® " (either polarity). One or more RESOL
VBus modules can be connected via this data bus:
®
• RESOL calorimeter
• RESOL large display / Smart Display
• RESOL Datalogger
Standard solar system with 1 store, 1 pump and 3 sensors.
The sensor S4 / TRF can be optionally used for heat quantity
measurement.
