Mains connection (1 ~) L1, N, PE (terminals 41, 42, 43, 44, 45)
CAUTION!
To operate 1 ~ motors (230 V AC), a jumper must be installed between input terminal L1 (41) and L2 (42),
and between N (44) and L3 (43). The supply line is connected to terminal L1 (41), the neutral conductor to
terminal N (44).
Power supply to the pumps (1~)
Pump 1 is connected to terminals V (28) and W (29), pump 2 to V (35) and W (36). The earth wires are
connected to the remaining PE terminals (30, 37) accordingly.
Thermal motor protection switches
Pump 1:
Pump 2:
In the case of pumps where the bimetal contact is switched so that it interrupts the power to the pump directly,
the message "No load" is displayed when the bimetal contact has tripped.
The pump cannot be started up again until after acknowledgement.

(The pump is not enabled until the Acknowledge button has been
pressed)
If temp. 1 is not used, the function must be disabled in the menu (see above Chapter 4.2).
If temp. 2 is not used, a wire jumper from terminal 32 to 33 must be used.

(The pump is automatically enabled after cooling)
Limiter contact (Temp 2) terminal 39/40
(The pump is not enabled until the Acknowledge button has been
pressed)
If temp. 1 is not used, the function must be disabled in the menu (see above Chapter 4.2).
If temp. 2 is not used, a wire jumper from terminal 39 to 40 must be used.
