On the control board
LTDC Version V3 + V4:
VFS1 Grundfos Direct Sensor
VFS2 Grundfos Direct Sensor
LTDC Version V1 + V4:
CAN CAN bus connection (1=high,2=low)
CAN CAN bus connection (1=high,2=low)
Terminal: Connection for:
S1 Temperature Sensor 1
S2 Temperature Sensor 2
S3 Temperature Sensor 3
S4 Temperature Sensor 4
S5 Temperature Sensor 5
V1 speed controlled output for 0-10V / PWM high-effi-
ciency pumps
LTDC Version V3 + V4:
V2 0-10V / PWM signal output e.g. for con-
trolling high-efficiency pumps
S6 Temperature Sensor 6
+12V Power supply
The connection of the ground wire is made at the lower gray terminal
block.
Terminal: Connection for:
N Neutral conductor N
L Network outer conductor L
R1 Relays 1
R2 Relays 2
R3| Relays 3|
R3 Relays 3
The neutral conductor N must be connected to the N terminal
block.
The PE protective conductor must be connected to the PE metal
terminal block!
In high-efficiency pumps with 0-10V / PWM signal input, the power
supply must go through the corresponding relay (V1 -> R1, R2 ->
V2), because the relay turns on and off together with the control
signals.
At R3I are permanently 230v when the relay is inactive. Wrong wiring can damage the connected components.
"Connection of PWM pumps"
PWM pumps are connected to the controller with 2 wires 1) PWM Input (default: brown) 2) GND (default: blue). Some pumps have
a third wire (PWM Output Signal (default: black)). This is not used for the connection!
