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.
