Heat source circuit

This is how the heat pump is wired when delivered.

The heat pump is connected to the mains on a single

tariff (one consumer meter) (1). The power company re-

serves the right to switch off the compressor and the

auxiliary heating as required by means of a ripple con-

trol signal. The duration and frequency of the shut-

downs is determined by the company, or should be clari-

fied with them.

• Connect the power supply to the principal 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.
