Heat source circuit

In this instance the heat pump is operated on two tariffs

(two consumer meters). A permanent supply (2) for the

secondary consumers (auxiliary heating, circulation

pumps, controller, etc.) must be ensured via a meter.

The low tariff supply (1) for the compressor is effected

via a second meter and can be interrupted by the power

company at peak times.

• Remove the jumpers (dashed lines, 3).

• Connect the permanent power supply to the high tar-

iff mains feed (2).

• Connect the low tariff power supply to the low tariff

mains feed (1).

• Connect the ripple control signal relay to terminal 13,

"EVU" (see Fig 6.6), if required by the power compa-

ny. The heat pump is blocked with this signal when the

contact is closed.

You will find an overview of the complete wiring dia-

gram in the appendix.
