Operating instructions PC-30-Vario filter control unit Page: 8
Connecting the heater
The terminal U2 is provided for the swimming pool heater. This output
supplies 230V and is rated for a maximum load of 3A.
In addition, a floating contact is provided at terminals 26+27 (e.g. for
controlling the boiler). This contact is rated for a maximum load of 230V,
3A.
An
230V solar actuator can be connected to terminals U5 and U6
for operating the solar heater. When solar heating is operating, the
mains voltage is applied to terminal U6 and no voltage is applied to
terminal U5.

A 4-wire connection is required for connecting the NR-12-TRS-2
water level controller. The wires must not be swapped over, i.e. they must be
connected to the same terminal at each end. The NR-12-TRS-2 additionally
requires a separate power supply.
Operating the PC-30-Vario without a NR-12-TRS-2 unit
If the PC-30-Vario is intended to be operated without an NR-12-TRS-2 unit,
terminals 13 and 14 must be connected together (with a link). Disconnect the
connecting cable before doing so. The four terminals are live and carry a
mains voltage.
